The following are health and medical definitions of terms that appear in the Depression article.
Abnormal: Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).
Absenteeism: The frequent absence from work or other duty without good reason. See also: Presenteeism.
Acetylcholine: A key chemical in neurons (nerve cells) that acts as a neurotransmitter and carries information across the synaptic cleft, the space between two nerve cells. Abbreviated ACh.
Acne: Localized skin inflammation as a result of overactivity of the oil glands at the base of hair follicles. Acne happens when oil (sebaceous) glands come to life around puberty, when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls. See the entire definition of Acne
Addiction: A chronic relapsing condition characterized by compulsive drug-seeking and abuse and by long-lasting chemical changes in the brain. Addiction is the same irrespective of whether the drug is alcohol, amphetamines, cocaine, heroin, marijuana, or nicotine. Every addictive substance induces pleasant states or relieves distress. Continued use of the addictive substance induces adaptive changes in the brain that lead to tolerance, physical dependence, uncontrollable craving and, all too often, relapse. Dependence is at such a point that stopping is very difficult and causes severe physical and mental reactions from withdrawal. The risk of addiction is in part inherited. Genetic factors, for example, account for about 40% of the risk of alcoholism. The genetic factors predisposing to addiction are not yet fully understood.
Alcoholism: Physical dependence on alcohol to the extent that stopping alcohol use will bring on withdrawal symptoms. In popular and therapeutic parlance, the term may also be used to refer to ingrained drinking habits that cause health or social problems. Treatment requires first ending the physical dependence, then making lifestyle changes that help the individual avoid relapse. In some cases, medication or hospitalization are needed. Alcohol dependence can have many serious effects on the brain, liver, and other organs of the body.
Alprazolam: A benzodiazepine sedative that causes dose-related depression of the central nervous system. Alprazolam is useful in treating anxiety, panic attacks, insomnia, and muscle spasms. The brand name is Xanax. A generic version is available.
Alternative medicine: Healing arts not taught in traditional Western medical schools that promote options to conventional medicine that is taught in these schools.. An example of an alternative therapy is using a special diet to treat cancer instead of undergoing surgery, radiation, or chemotherapy that has been recommended by a Western physician. Complementary medicine is different from alternative medicine. Whereas complementary medicine is used together with conventional medicine, alternative medicine is used in place of conventional medicine. See also complementary medicine, conventional medicine.
Amitriptyline: An antidepressant medication. In some patients with depression, abnormal levels of brain chemicals called neurotransmitters may relate to the depression. Amitriptyline elevates mood by raising the level of neurotransmitters in brain tissue. Amitriptyline is also a sedative that is useful for depressed patients with insomnia, restlessness, and nervousness. It is sometimes used to treat fibromyalgia and symptoms related to chronic pain. Brand names are Elavil and Endep. A generic version is available.
Anesthesia: Loss of feeling or awareness. A general anesthetic puts the person to sleep. A local anesthetic causes loss of feeling in a part of the body such as a tooth or an area of skin without affecting consciousness. Regional anesthesia numbs a larger part of the body such as a leg or arm, also without affecting consciousness. The term "conduction anesthesia" encompasses both local and regional anesthetic techniques. Many surgical procedures can be done with conduction anesthesia without significant pain. In many situations, such as a C-section, conduction anesthesia is safer and therefore preferable to general anesthesia. However, there are also many types of surgery in which general anesthesia is clearly appropriate.
Anorgasmia: Failure to achieve orgasm (climax) during sexual intercourse. Anorgasmia can result from many causes including stress, anxiety, depression, fatigue, worry, guilt, fear of painful intercourse, fear of pregnancy, the undesirability of a partner, the undesirability of a setting, and the use of alcohol, prescription or illicit drugs. In women, this problem is also referred to as "frigidity," or female orgasmic dysfunction. See the entire definition of Anorgasmia
Anticholinergic: The action of certain medications that inhibit the transmission of parasympathetic nerve impulses and thereby reduce spasms of smooth muscle (such as that, for example, in the bladder).
Antidepressant: Anything, and especially a drug, used to prevent or treat depression. See the entire definition of Antidepressant
Antidepressants: Anything, and especially a drug, used to prevent or treat depression. See the entire definition of Antidepressants
Antipsychotic: A medication (or another measure) that is believed to be effective in the treatment of psychosis. For example, aripiprazole (Abilify) is an antipsychotic medication used to treat schizophrenia.
Anxiety: A feeling of apprehension and fear characterized by physical symptoms such as palpitations, sweating, and feelings of stress. Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults. These disorders fill people's lives with overwhelming anxiety and fear. Unlike the relatively mild, brief anxiety caused by a stressful event such as a business presentation or a first date, anxiety disorders are chronic, relentless, and can grow progressively worse if not treated. See the entire definition of Anxiety
Artery: A vessel that carries blood high in oxygen content away from the heart to the farthest reaches of the body. Since blood in arteries is usually full of oxygen, the hemoglobin in the red blood cells is oxygenated. The resultant form of hemoglobin (oxyhemoglobin) is what makes arterial blood look bright red. See the entire definition of Artery
Asthma: A common disorder in which chronic inflammation of the bronchial tubes (bronchi) makes them swell, narrowing the airways. Asthma involves only the bronchial tubes and does not affect the air sacs (alveoli) or the lung tissue (the parenchyma of the lung) itself. See the entire definition of Asthma
Attention deficit hyperactivity disorder: A family of related chronic neurobiological disorders that interfere with an individual's capacity to:
regulate activity level (hyperactivity),
inhibit behavior (impulsivity), and
attend to tasks (inattention) in developmentally appropriate ways. The term "attention deficit hyperactivity disorder" is abbreviated and usually referred to as ADHD.
The core symptoms of ADHD include an inability to sustain attention and concentration, developmentally inappropriate levels of activity, distractibility, and impulsivity. See the entire definition of Attention deficit hyperactivity disorder
Atypical: Not typical, not usual, not normal, abnormal. Atypical is often used to refer to the appearance of precancerous or cancerous cells.
Baby blues: A common temporary psychological state right after childbirth when a new mother may have sudden mood swings, feeling very happy, then very sad, cry for no apparent reason, feel impatient, unusually irritable, restless, anxious, lonely and sad. The baby blues may last only a few hours or as long as 1 to 2 weeks after delivery. The baby blues in this sense are less severe than a postpartum depression. The baby blues do not always require treatment from a health care provider. Often, joining a support group of new mothers or talking with other mothers helps. See the entire definition of Baby blues
Benign: Not cancer. Not malignant. A benign tumor does not invade surrounding tissue or spread to other parts of the body. A benign tumor may grow but it stays put (in the same place). See the entire definition of Benign
Bile: Bile is a yellow-green fluid that is made by the liver, stored in the gallbladder and passes through the common bile duct into the duodenum where it helps digest fat. The principal components of bile are cholesterol, bile salts, and the pigment bilirubin. See the entire definition of Bile
Biochemical: Relating to biochemistry, the application of the tools and concepts of chemistry to living systems. See the entire definition of Biochemical
Bipolar disorder: A mood disorder sometimes called manic-depressive illness or manic-depression that characteristically involves cycles of depression and elation or mania. Sometimes the mood switches from high to low and back again are dramatic and rapid, but more often they are gradual and slow, and intervals of normal mood may occur between the high (manic) and low (depressive) phases of the condition. The symptoms of both the depressive and manic cycles may be severe and often lead to impaired functioning. See the entire definition of Bipolar disorder
Bipolar I disorder: Bipolar disorder in someone who has experienced depression and at least one episode of severe mania. Severe mania characteristically causes significant distress or greatly impairs one's work, family, or social life. See the entire definition of Bipolar I disorder
Bipolar II disorder: Bipolar disorder in someone who has experienced depression and at least one episode of hypomania but not severe mania. Hypomanic episodes characteristically do not cause significant distress or greatly impair one's work, family, or social life. See the entire definition of Bipolar II disorder
Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called "hypertension".
Blurred vision: Lack of sharpness of vision with, as a result, the inability to see fine detail. Blurred vision can occur when a person who wears corrective lens is without them. Blurred vision can also be an important clue to eye disease.
Brain: That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called "hemispheres."
Cancer: An abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread). See the entire definition of Cancer
Carbohydrate: Mainly sugars and starches, together constituting one of the three principal types of nutrients used as energy sources (calories) by the body. Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. See the entire definition of Carbohydrate
Cell: The basic structural and functional unit in people and all living things. Each cell is a small container of chemicals and water wrapped in a membrane. See the entire definition of Cell
Chronic: This important term in medicine comes from the Greek chronos, time and means lasting a long time. See the entire definition of Chronic
Chronic illness: An illness that persists for a long period of time. The term "chronic" comes from the Greek chronos, time and means lasting a long time. See the entire definition of Chronic illness
Chronic pain: Pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments. See the entire definition of Chronic pain
Clinical depression:Depression that meets the DSM-IV criteria for a depressive disorder. The term is usually used to denote depression that is not a normal, temporary mood caused by life events or grieving.
Clinical trials: Trials to evaluate the effectiveness and safety of medications or medical devices by monitoring their effects on large groups of people. See the entire definition of Clinical trials
Constipation: Infrequent (and frequently incomplete) bowel movements. The opposite of diarrhea, constipation is commonly caused by irritable bowel syndrome, diverticulosis, and medications (constipation can paradoxically be caused by overuse of laxatives). Colon cancer can narrow the colon and thereby cause constipation. The large bowel (colon) can be visualized by barium enema x-rays, sigmoidoscopy, and colonoscopy. Barring a condition such as cancer, high-fiber diets can frequently relieve the constipation.
Coronary artery disease: A major cause of illness and death, coronary artery disease (CAD) begins when hard cholesterol substances (plaques) are deposited within a coronary artery. See the entire definition of Coronary artery disease
Cough: A rapid expulsion of air from the lungs typically in order to clear the lung airways of fluids, mucus, or material. Also called tussis.
Cymbalta: Brand name for duloxetine hydrochloride, a drug approved by the FDA to treat major depresssion in adults and to manage the pain associated with diabetic peripheral neuropathy, nerve damage in diabetes. The drug acts as a serotonin and norepinephrine reuptake inhibitor, increasing the levels of serotonin and norepinephrine, two neurotransmitters, or chemical messengers, believed to be important in regulating a person's emotions as well as reducing the sensitivity to pain.
Delirium: A sudden state of severe confusion and rapid changes in brain function, sometimes associated with hallucinations and hyperactivity, in which the patient is inaccessible to normal contact. Symptoms may include inability to concentrate and disorganized thinking evidenced by rambling, irrelevant, or incoherent speech. There may be a reduced level of consciousness, sensory misperceptions and illusions, disturbances of sleep, drowsiness, disorientation to time, place, or person, and problems with memory. See the entire definition of Delirium
Dementia: Significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. See the entire definition of Dementia
Depression: An illness that involves the body, mood, and thoughts, that affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood. It is not a sign of personal weakness or a condition that can be wished away. People with a depressive disease cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression. See the entire definition of Depression
Diabetes: Refers to diabetes mellitus or, less often, to diabetes insipidus. Diabetes mellitus and diabetes insipidus share the name "diabetes" because they are both conditions characterized by excessive urination (polyuria). See the entire definition of Diabetes
Diagnosis:1 The nature of a disease; the identification of an illness. 2 A conclusion or decision reached by diagnosis. The diagnosis is rabies. 3 The identification of any problem. The diagnosis was a plugged IV. See the entire definition of Diagnosis
Diarrhea: A familiar phenomenon with unusually frequent or unusually liquid bowel movements, excessive watery evacuations of fecal material. The opposite of constipation. The word "diarrhea" with its odd spelling is a near steal from the Greek "diarrhoia" meaning "a flowing through." Plato and Aristotle may have had diarrhoia while today we have diarrhea. There are myriad infectious and noninfectious causes of diarrhea. See the entire definition of Diarrhea
Dizziness: Painless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo. See the entire definition of Dizziness
Dopamine: An important neurotransmitter (messenger) in the brain. See the entire definition of Dopamine
Dry mouth: The condition of not having enough saliva to keep the mouth wet. This is due to inadequate function of the salivary glands. Everyone has dry mouth once in a while when they are nervous, upset or under stress. But if someone has a dry mouth most all of the time, it can be uncomfortable and lead to serious health problems. See the entire definition of Dry mouth
Dysthymia: A type of depression involving long-term, chronic symptoms that are not disabling, but keep a person from functioning at "full steam" or from feeling good. Dysthymia is a less severe type of depression than what is accorded the diagnosis of major depression. However, people with dysthymia may also sometimes experience major depressive episodes, suggesting that there is a continuum between dysthymia and major depression.
Ejaculate: To ejaculate is to release semen during an orgasm in a male. See the entire definition of Ejaculate
Electroconvulsive therapy: A procedure in which an electric current is passed through the brain to produce controlled convulsions (seizures) to treat patients with depression, particularly for those who cannot take or are not responding to antidepressants, have severe depression, or are at high risk for suicide. Electroconvulsive therapy (ECT) is believed to act by a massive neurochemical release in the brain due to the controlled seizure. The most common side effect is short-term memory loss, which usually resolves quickly. ECT typically relieves depression within 1 to 2 weeks after beginning treatments.
Endogenous: Inside. For example, endogenous cholesterol is cholesterol that is made inside the body and is not in the diet.
Enzyme: A protein (or protein-based molecule) that speeds up a chemical reaction in a living organism. An enzyme acts as catalyst for specific chemical reactions, converting a specific set of reactants (called substrates) into specific products. Without enzymes, life as we know it would not exist. See the entire definition of Enzyme
Euphoria: Elevated mood. Euphoria is a desirable and natural occurrence when it results from happy or exciting events. An excessive degree of euphoria that is not linked to events is characteristic of hypomania or mania, abnormal mood states associated with bipolar disorders. See the entire definition of Euphoria
Family history: The family structure and relationships within the family, including information about diseases in family members. See the entire definition of Family history
Fatigue: A condition characterized by a lessened capacity for work and reduced efficiency of accomplishment, usually accompanied by a feeling of weariness and tiredness. Fatigue can be acute and come on suddenly or chronic and persist. See the entire definition of Fatigue
FDA: The Food and Drug Administration, an agency within the U.S. Public Health Service, which is a part of the Department of Health and Human Services. See the entire definition of FDA
Fetus: The unborn offspring from the end of the 8th week after conception (when the major structures have formed) until birth. Up until the eighth week, the developing offspring is called an embryo.
Folate: Folic acid, one of the B vitamins that is a key factor in the synthesis (the making) of nucleic acid (DNA and RNA). See the entire definition of Folate

Genetic: Having to do with genes and genetic information.
Glaucoma: A common eye condition in which the fluid pressure inside the eyes rises because of slowed fluid drainage from the eye. If untreated, it may damage the optic nerve and other parts of the eye, causing the loss of vision or even blindness. See the entire definition of Glaucoma
Grief: The normal process of reacting to a loss. The loss may be physical (such as a death), social (such as divorce), or occupational (such as a job). Emotional reactions of grief can include anger, guilt, anxiety, sadness, and despair. Physical reactions of grief can include sleeping problems, changes in appetite, physical problems, or illness. See the entire definition of Grief
Headache: A pain in the head with the pain being above the eyes or the ears, behind the head (occipital), or in the back of the upper neck. Headache, like chest pain or back ache, has many causes. See the entire definition of Headache
Heart: The muscle that pumps blood received from veins into arteries throughout the body. It is positioned in the chest behind the sternum (breastbone; in front of the trachea, esophagus, and aorta; and above the diaphragm muscle that separates the chest and abdominal cavities. The normal heart is about the size of a closed fist, and weighs about 10.5 ounces. It is cone-shaped, with the point of the cone pointing down to the left. Two-thirds of the heart lies in the left side of the chest with the balance in the right chest. See the entire definition of Heart
Heart rate: The number of heart beats per unit time, usually per minute. The heart rate is based on the number of contractions of the ventricles (the lower chambers of the heart). The heart rate may be too fast (tachycardia) or too slow (bradycardia). The pulse is bulge of an artery from the wave of blood coursing through the blood vessel as a result of the heart beat. The pulse is often taken at the wrist to estimate the heart rate.
Herbal:1. An adjective, referring to herbs, as in an herbal tea. 2. A noun, usually reflecting the botanical or medicinal aspects of herbs; also a book which catalogs and illustrates herbs. The word "herbal" was pronounced with a silent "h" on both sides of the Atlantic until the 19th century but this usage persists only on the American side.
Herbal remedy: A medication prepared from plants, including most of the world's traditional remedies for disease. Most people think of herbal remedies as products sold over the counter as "supplements", such as saw palmetto extract or goldenseal ointment. However, many over- the-counter and prescription drugs are based on ingredients originally derived from plants, including aspirin and digoxin. Lab tests have shown that some herbal remedies are indeed effective against illness. One should use these drugs as carefully as prescription medicines, taking care to avoid overdose, interactions with other medications, and misuse.
High blood pressure: Also known as hypertension, high blood pressure is, by definition, a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90. See the entire definition of High blood pressure
Hippocrates: (c.460-377BC) Great Greek physician on the Mediterranean island of Cos, who founded a medical school there, and is regarded as the "Father of Medicine." That is the standard view of Hippocrates. But, in truth, virtually nothing is known of the first physician named Hippocrates. There are considered to have been several by that name, all of them teachers at the famous medical school on the island of Cos. It was in the 5th century BCE, however, that Hippocrates' name and image began to emerge as a leader in medical research and thought. See the entire definition of Hippocrates
Histamine: Substance that plays a major role in many allergic reactions. Histamine dilates blood vessels and makes the vessel walls abnormally permeable.
HIV: Acronym for the Human Immunodeficiency Virus, the cause of AIDS (acquired immunodeficiency syndrome). HIV has also been called the human lymphotropic virus type III, the lymphadenopathy-associated virus and the lymphadenopathy virus. No matter what name is applied, it is a retrovirus. (A retrovirus has an RNA genome and a reverse transcriptase enzyme. Using the reverse transcriptase, the virus uses its RNA as a template for making complementary DNA which can integrate into the DNA of the host organism). See the entire definition of HIV
Homosexual: A person sexually attracted to persons of the same sex. Homosexuals include males (gays) and females (lesbians). See the entire definition of Homosexual
Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. See the entire definition of Hormone

Hypertension: High blood pressure, defined as a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90. See the entire definition of Hypertension
Hypertrophy: Enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells. Hypertrophy occurs in the biceps and heart because of increased work. Cardiac hypertrophy is recognizable microscopically by the increased size of the cells. The term hypertrophy is applied to the enlargement of the uterus during pregnancy. The term benign prostatic hypertrophy is a misnomer because the increased size of the prostate is due to hyperplasia, an increase in the number of cells.
Hypomania: A condition similar to mania but less severe. The symptoms are similar with elevated mood, increased activity, decreased need for sleep, grandiosity, racing thoughts, and the like. However, hypomanic episodes differ in that they do not cause significant distress or impair one's work, family, or social life in an obvious way while manic episodes do. See the entire definition of Hypomania
Hypotension: Any blood pressure that is below the normal expected for an individual in a given environment. Hypotension is the opposite of hypertension (abnormally high blood pressure). See the entire definition of Hypotension
Incidence: The frequency with which something, such as a disease, appears in a particular population or area. In disease epidemiology, the incidence is the number of newly diagnosed cases during a specific time period. The incidence is distinct from the prevalence which refers to the number of cases alive on a certain date.
Inheritance: Not something that is contained in a will, but rather a gene, chromosome or genome that is transmitted from parent to child. See the entire definition of Inheritance
Insomnia: The perception or complaint of inadequate or poor-quality sleep because of one or more of the following: difficulty falling asleep; waking up frequently during the night with difficulty returning to sleep; waking up too early in the morning; or unrefreshing sleep. Insomnia is not defined by the number of hours of sleep a person gets or how long it takes to fall asleep. Individuals vary normally in their need for, and their satisfaction with, sleep. Insomnia may cause problems during the day, such as tiredness, a lack of energy, difficulty concentrating, and irritability. See the entire definition of Insomnia
Intervention: The act of intervening, interfering or interceding with the intent of modifying the outcome. In medicine, an intervention is usually undertaken to help treat or cure a condition. For example, early intervention may help children with autism to speak. "Acupuncture as a therapeutic intervention is widely practiced in the United States," according to the National Institutes of Health. From the Latin intervenire, to come between.
Laboratory: A place for doing tests and research procedures and preparing chemicals, etc. Although "laboratory" looks very like the Latin "laboratorium" (a place to labor, a work place), the word "laboratory" came from the Latin "elaborare" (to work out, as a problem, and with great pains), as evidenced by the Old English spelling "elaboratory" designating "a place where learned effort was applied to the solution of scientific problems."
Libido:1. Sexual drive. 2. In psychoanalysis, the psychic energy from all instinctive biological drives. See the entire definition of Libido
Lithium: Lithium carbonate (brand names: Eskalith; Lithobid), a drug used as a mood stabilizer for the treatment of manic/depressive (bipolar) disorder. It prevents or diminishes the intensity of episodes of mania in bipolar patients. Typical symptoms of mania include pressure of speech, motor hyperactivity, reduced need for sleep, flight of ideas, grandiosity, elation, poor judgment, aggressiveness and possibly hostility. See the entire definition of Lithium
Liver: An organ in the upper abdomen that aids in digestion and removes waste products and worn-out cells from the blood. The liver is the largest solid organ in the body. The liver weighs about three and a half pounds (1.6 kilograms). It measures about 8 inches (20 cm) horizontally (across) and 6.5 inches (17 cm) vertically (down) and is 4.5 inches (12 cm) thick.
Low blood pressure: Any blood pressure that is below the normal expected for an individual in a given environment. Low blood pressure is also referred to as hypotension. See the entire definition of Low blood pressure
Major depression: A disease with certain characteristic signs and symptoms that interferes with the ability to work, sleep, eat, and enjoy once pleasurable activities. See the entire definition of Major depression
Mania: An abnormally elevated mood state characterized by such symptoms as inappropriate elation, increased irritability, severe insomnia, grandiose notions, increased speed and/or volume of speech, disconnected and racing thoughts, increased sexual desire, markedly increased energy and activity level, poor judgment, and inappropriate social behavior. A mild form in mania that does not require hospitalization is termed hypomania. Mania that also features symptoms of depression ("agitated depression") is called mixed mania. See the entire definition of Mania
Manic: Refers to a mood disorder in which a person seems "high", euphoric, expansive, sometimes agitated, hyperexcitable, with flights of ideas and speech.

Memory:1. The ability to recover information about past events or knowledge. 2. The process of recovering information about past events or knowledge. 3. Cognitive reconstruction. The brain engages in a remarkable reshuffling process in an attempt to extract what is general and what is particular about each passing moment. See the entire definition of Memory
Menopause: The time in a woman's life when menstrual periods permanently stop; it is also called the "change of life." Menopause is the opposite of the menarche. See the entire definition of Menopause
Morbidity: Illness, disease.
Mortality: A fatal outcome or, in one word, death. The word "mortality" is derived from "mortal" which came from the Latin "mors" (death). The opposite of mortality is, of course, immortality. Mortality is also quite distinct from morbidity (illness). See the entire definition of Mortality
Mouth:1. The upper opening of the digestive tract, beginning with the lips and containing the teeth, gums, and tongue. Foodstuffs are broken down mechanically in the mouth by chewing and saliva is added as a lubricant. Saliva contains amylase, an enzyme that digests starch. 2. Any opening or aperture in the body. The mouth in both senses of the word is also called the os, the Latin word for an opening, or mouth. The o in os is pronounced as in hope. The genitive form of os is oris from which comes the word oral.
Nausea:Nausea, is the urge to vomit. It can be brought by many causes including, systemic illnesses, such as influenza, medications, pain, and inner ear disease. When nausea and/or vomiting are persistent, or when they are accompanied by other severe symptoms such as abdominal pain, jaundice, fever, or bleeding, a physician should be consulted.
Neck: The part of the body joining the head to the shoulders. Also, any narrow or constricted part of a bone or organ that joins its parts as, for example, the neck of the femur bone.

Neurological: Having to do with the nerves or the nervous system.
Neuron: A nerve cell that sends and receives electrical signals over long distances within the body. A neuron may send electrical output signals to muscle neurons (called motor neurons or motoneurons) and to other neurons. A neuron may receive electrical input signals from sensory cells (called sensory neurons) and from other neurons. A neuron that simply signals another neuron is called an interneuron. See the entire definition of Neuron
Neurotransmitter: A chemical that is released from a nerve cell which thereby transmits an impulse from a nerve cell to another nerve, muscle, organ, or other tissue. A neurotransmitter is a messenger of neurologic information from one cell to another.
NIMH: Stands for the National Institute of Mental Health, one of the National Institutes of Health in the U.S., whose mission is to "provide national leadership dedicated to understanding, treating, and preventing mental illnesses through basic research on the brain and behavior, and through clinical, epidemiological, and services research."
Obesity: The state of being well above one's normal weight. See the entire definition of Obesity
Objective: In a microscope, the objective (also called the objective lens) is the lens nearest to the object being examined whereas the lens closest to the eye is termed the ocular (the eyepiece). See the entire definition of Objective
Onset: In medicine, the first appearance of the signs or symptoms of an illness as, for example, the onset of rheumatoid arthritis. There is always an onset to a disease but never to the return to good health. The default setting is good health. See the entire definition of Onset
Orgasm: The climax of coitus, consisting of a series of involuntary muscle contractions in the anus, lower pelvic muscles, and sexual organs, accompanied by a sudden release of endorphins providing a feeling of euphoria. See the entire definition of Orgasm
Orthostatic hypotension: A temporary lowering of blood pressure (hypotension) due usually to suddenly standing up (orthostatic). Orthostatic hypotension may be experienced by healthy people -- it is more common in older people -- who rise quickly from a chair, especially after a meal, and have a few seconds of disorientation. See the entire definition of Orthostatic hypotension
Outpatient: A patient who is not an inpatient (not hospitalized) but instead is cared for elsewhere -- as in a doctor's office, clinic, or day surgery center. The term outpatient dates back at least to 1715. Outpatient care today is also called ambulatory care.
Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia. Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors. See the entire definition of Pain
Perimenopause: The time in a woman's life when physiological changes occur that begin the transition to menopause. Menopause is the time when there have been no menstrual periods for 12 consecutive months. A woman can usually tell if she is experiencing symptoms characteristic of the perimenopause because her menstrual periods start changing. See the entire definition of Perimenopause
Pharmacogenetics: The merger of pharmacology and genetics into a field that pertains to the hereditary responses to drugs. For example, after the administration of a muscle relaxant drug, a patient may remain apneic for hours due to a genetically determined defect in metabolizing (processing) the muscle relaxant. See the entire definition of Pharmacogenetics
Physiology: The study of how living organisms function including such processes as nutrition, movement, and reproduction. See the entire definition of Physiology
Placebo: A "sugar pill" or any dummy medication or treatment. See the entire definition of Placebo
Postpartum: In the period just after delivery, as with postpartum depression. Postpartum refers to the mother and postnatal to the baby. From the Latin post, after + partum, birth.
Postpartum depression: A form of severe depression after delivery that requires treatment. It is sometimes said that postpartum depression (PPD) occurs within 4 weeks of delivery but it can happen a few days or even months after childbirth. A woman with PPD may have feelings similar to the baby blues -- sadness, despair, anxiety, irritability -- but she feels them much more strongly than she would with the baby blues. PPD often keeps her from doing the things she needs to do every day. When a woman's ability to function is affected, this is a sure sign that she needs treatment. If a woman does not get treatment for PPD, it can get worse and last for as long as a year. While PPD is a serious condition, it can be effectively treated with antidepressant medications and counseling.
Postpartum psychosis: A very serious mental illness that can affect a new mother. The episode of psychosis usually begins within 1 to 3 months of delivery. A woman with postpartum psychosis may lose touch with reality and have auditory hallucinations (hearing things that are not actually happening, like a person talking) and delusions (perceiving things differently from the way they are). Visual hallucinations ((seeing things that are not there) are less common. Other symptoms may include insomnia, agitation, anger, and irrational guilt about somehow having done something wrong. Women who have postpartum psychosis need prompt treatment and almost always need medication. If they are at risk for hurting themselves or someone else, women with postpartum psychosis need to be in a hospital.
Predispose: To make more likely or render susceptible. Smoking predisposes to a number of diseases, including esophageal cancer.
Pregnancy: The state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the date of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long.

Recurrent: Back again. A recurrent fever is a fever that has returned after an intermission: a recrudescent fever.
Referral: The recommendation of a medical or paramedical professional. If you get a referral to ophthalmology, for example, you are being sent to the eye doctor. In HMOs and other managed care schemes, a referral is usually necessary to see any practitioner or specialist other than your primary care physician (PCP), if you want the service to be covered. The referral is obtained from your PCP, who may require a telephone or office consultation first. See the entire definition of Referral
Regress: To return or go back, particularly to return to a pattern of behavior or level of skill characteristic of a younger age. For example, if a three-year-old child begins to regress by losing the ability to control his bowels or speak, that is a cause for medical concern. In reference to a disease, to "regress," means tending to worsen.
Remedy: Something that consistently helps treat or cure a disease. From the Latin "remedium" meaning that which heals again (and again). See the entire definition of Remedy
Reuptake: The reabsorption of a secreted substance by the cell that originally produced and secreted it. The process of reuptake, for example, affects serotonin. See the entire definition of Reuptake
Robust: In statistics, a term applied to a test or procedure that is not seriously disturbed by violations of the assumptions on which it is based. For example, it was an "unexpected and robust difference in the rate of events." (Dr. Harold J. Burstein, in The New England Journal of Medicine, Oct 9, 2003)
Rule out: A term much used in medicine, meaning to eliminate or exclude something from consideration. The ACB (albumin cobalt binding) test helps rule out a heart attack in the differential diagnosis of severe chest pain.
Saliva: a watery secretion in the mouth produced by the salivary glands that aids in the digestion of food. Saliva also serves to moisten and cleanse the mouth, including the tongue and teeth, and contains substances that can play a role in the prevention of infection. Saliva aids digestion by moistening food and contains enzymes that begin the digestion process. Also known as spit.
SAMHSA: The Substance Abuse and Mental Health Services Administration, a part of the U.S. Public Health Service, that works to improve the quality and availability of substance abuse prevention, addiction treatment, and mental health services. Provides funding through block grants to states for direct substance abuse and mental health services, including treatment for over 340,000 Americans with serious substance abuse problems. Helps improve substance abuse treatment through its Knowledge Development and Applications grant program. Monitors prevalence and incidence of substance abuse and mental illness. Established: 1992. (A predecessor agency, the Alcohol, Drug Abuse and Mental Health Administration, was established in 1974.) Headquarters: Rockville, MD.
Schizophrenia: One of several brain diseases whose symptoms that may include loss of personality (flat affect), agitation, catatonia, confusion, psychosis, unusual behavior, and withdrawal. The illness usually begins in early adulthood. See the entire definition of Schizophrenia
Seizure: Uncontrolled electrical activity in the brain, which may produce a physical convulsion, minor physical signs, thought disturbances, or a combination of symptoms. See the entire definition of Seizure
Sensation: In medicine and physiology, sensation refers to the registration of an incoming (afferent) nerve impulse in that part of the brain called the sensorium, which is capable of such perception. Therefore, the awareness of a stimulus as a result of its perception by sensory receptors. (Sensory is here synonymous with sensation.) See the entire definition of Sensation
Serotonin: A hormone, also called 5-hydroxytryptamine, in the pineal gland, blood platelets, the digestive tract, and the brain. Serotonin acts both as a chemical messenger that transmits nerve signals between nerve cells and that causes blood vessels to narrow. See the entire definition of Serotonin
SPECT: An acronym that stands for Single Photon Emission Computed Tomography, a nuclear medicine procedure in which a gamma camera rotates around the patient and takes pictures from many angles, which a computer then uses to form a tomographic (cross-sectional) image. See the entire definition of SPECT
SSRI: Abbreviation for selective serotonin reuptake inhibitors, commonly prescribed drugs for treating depression. SSRIs affect the chemicals that nerves in the brain use to send messages to one another. These chemical messengers, called neurotransmitters, are released by one nerve and taken up by other nerves. Neurotransmitters that are not taken up by other nerves are taken up by the same nerves that released them. This process is termed "reuptake." SSRIs work by inhibiting the reuptake of serotonin, an action which allows more serotonin to be available to be taken up by other nerves. See the entire definition of SSRI
Stress: Forces from the outside world impinging on the individual. Stress is a normal part of life that can help us learn and grow. Conversely, stress can cause us significant problems. See the entire definition of Stress

Surgeon: A physician who treats disease, injury, or deformity by operative or manual methods. A medical doctor specialized in the removal of organs, masses and tumors and in doing other procedures using a knife (scalpel). The definition of a "surgeon" has begun to blur in recent years as surgeons have begun to minimize the cutting, employ new technologies that are "minimally invasive," use scopes, etc. See the entire definition of Surgeon
Symptom: Any subjective evidence of disease. Anxiety, lower back pain, and fatigue are all symptoms. They are sensations only the patient can perceive. In contrast, a sign is objective evidence of disease. A bloody nose is a sign. It is evident to the patient, doctor, nurse and other observers.
Synapse: The point of connection usually between two nerve cells. Specifically, a synapse is a specialized junction at which a nerve cell (a neuron) communicates with a target cell. The neuron releases a chemical transmitter (a neurotransmitter) that diffuses across a small gap and activates specific specialized sites called receptors situated on the target cell. The target cell may be another neuron, or a specialized region of a muscle cell or a secretory cell (a cell than can make and secrete a substance). Neurons can also communicate through direct electrical connections (electrical synapses). See the entire definition of Synapse
Syndrome: A set of signs and symptoms that tend to occur together and which reflect the presence of a particular disease or an increased chance of developing a particular disease. See the entire definition of Syndrome

Vitamin B12: A vitamin important for the normal formation of red blood cells and the health of the nerve tissues. Undetected and untreated vitamin B12 deficiency can lead to anemia and permanent nerve and brain damage. See the entire definition of Vitamin B12
Vitamin D: A steroid vitamin which promotes the intestinal absorption and metabolism of calcium and phosphorus. Under normal conditions of sunlight exposure, no dietary supplementation is necessary because sunlight promotes adequate vitamin D synthesis in the skin. Deficiency can lead to bone deformity (rickets) in children and bone weakness (osteomalacia) in adults. See the entire definition of Vitamin D
Vitamins: The word "vitamin" was coined in 1911 by the Warsaw-born biochemist Casimir Funk (1884-1967). At the Lister Institute in London, Funk isolated a substance that prevented nerve inflammation (neuritis) in chickens raised on a diet deficient in that substance. He named the substance "vitamine" because he believed it was necessary to life and it was a chemical amine. The "e" at the end was later removed when it was recognized that vitamins need not be amines. See the entire definition of Vitamins
Weight loss: Weight loss is a decrease in body weight resulting from either voluntary (diet, exercise) or involuntary (illness) circumstances. Most instances of weight loss arise due to the loss of body fat, but in cases of extreme or severe weight loss, protein and other substances in the body can also be depleted. Examples of involuntary weight loss include the weight loss associated with cancer, malabsorption (such as from chronic diarrheal illnesses ), and chronic inflammation (such as with rheumatoid arthritis).
X-ray:1. High-energy radiation with waves shorter than those of visible light. X-rays possess the properties of penetrating most substances (to varying extents), of acting on a photographic film or plate (permitting radiography), and of causing a fluorescent screen to give off light (permitting fluoroscopy). In low doses X-rays are used for making images that help to diagnose disease, and in high doses to treat cancer. Formerly called a Roentgen ray. 2. An image obtained by means of X-rays.
Anxiety is a feeling of apprehension and fear characterized by physical symptoms. Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults.
Panic attacks are sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. A person experiencing a panic attack may believe that he or she is having a heart attack or that death is imminent. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms: racing heartbeat, faintness, dizzyness, numbness or tingling in the hands and fingers, chills, chest pains, difficulty breathing, and a feeling of loss or control. There are several treatments for panic attacks.
HIV (human immunodeficiency virus) is the cause of AIDS (acquired immunodeficiency syndrome). HIV is a type of virus called a retrovirus, which infects humans when it comes in contact with a break in the skin or tissues such as those that line the vagina, anal area, mouth, or eyes.
Lyme disease is a bacterial illness, which is spread by ticks when they bite the skin. Initially the disease affects the skin causing a reddish rash associated with flu-like symptoms. It takes weeks to months after the initial redness of the skin for its effects to spread throughout the body. Lyme disease can be treated with antibiotics. Lyme disease can be prevented by using tick avoidance techniques.
Fibromyalgia, formerly
known as fibrositis, causes chronic pain, stiffness, and
tenderness of muscles, tendons, and joints without detectable inflammation. Fibromyalgia patients have an unusually low pain threshold. Symptoms of fibromyalgia include fatigue, abnormal sleep, mental/emotional disturbances, abdominal pain, migraine and tension headaches, and irritable bladder. Treatment of fibromyalgia involves patient education, medication, exercise, and stress reduction.
Stress occurs when forces from the outside world impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
Sarcoidosis, a disease resulting from chronic inflammation, causes small lumps (granulomas) to develop in a great range of body tissues and can appear in almost any body organ. However, sarcoidosis most often starts in the lungs or lymph nodes.
Anorexia is an eating disorder characterized by markedly reduced appetite or total aversion to food. Anorexia is a serious psychological disorder and is a condition that goes well beyond out-of-control dieting. With anorexia, the drive to become thinner is actually secondary to concerns about control and/or fears relating to one's body. There are psychological and behavioral symptoms as well as physical symptoms of anorexia including: depression, social withdrawal, fatigue, food obsession, heart and gastrointestinal complications, kidney function, flaky skin, brittle nails, and tooth loss (this list is not exhaustive).
Alcoholism is a disease that includes alcohol craving and continued drinking despite repeated alcohol-related problems, such as losing a job or getting into trouble with the law.
Post-traumatic stress disorder (PTSD), a psychiatric condition, can develop after any catastrophic life event. Symptoms include nightmares, flashbacks, sweating, rapid heart rate, detachment, amnesia, sleep problems, irritability, and exaggerated startle response. Treatment may involve psychotherapy, group support, and medication.
Schizophrenia is a disabling brain disorder that may cause hallucinations and delusions and affect a person's ability to communicate and pay attention. Symptoms of psychosis appear in men in their late teens and early 20s and in women in their mid-20s to early 30s. With treatment involving the use of antipsychotic medications and psychosocial treatment, schizophrenia patients can lead rewarding and meaningful lives.
Impotence, also known as erectile dysfunction, is a common
problem among men characterized by the consistent inability to sustain an
erection sufficient for sexual intercourse or the inability to achieve
ejaculation, or both. Impotence can have emotional causes but most often it is
due to a physical problem.
Suicide is the process of intentionally ending one's own life. Approximately 1 million people worldwide commit suicide each year, and 10 million to 20 million attempt suicide annually.
Bipolar disorder (or manic depression) is a mental illness characterized by depression, mania, and severe mood swings. Treatment may incorporate mood stabilizer medications, antidepressants, and psychotherapy.
Borderline personality disorder is a serious mental illness characterized by pervasive instability in moods, interpersonal relationships, self-image, and behavior. This instability often disrupts family and work life, long-term planning, and the individual's sense of self-identity. Originally thought to be at the "borderline" of psychosis, people with borderline personality disorder (BPD) suffer from a disorder of emotion regulation.
Dissociative identity disorder (formerly known as multiple personality disorder or split personality disorder) is a mental illness in which a person has at least two distinct personalities. Symptoms and signs include lapses in memory, feeling unreal, blackouts in time, hearing voices in their head that are not their own, not recognizing themselves in the mirror, and finding items in one's possession but not recalling how they were acquired. Treatment usually involves psychotherapy, medications, and sometimes hypnosis.
Cushing's syndrome, sometimes referred to as hypercortisolism, is a hormonal disorder caused by prolonged exposure to high levels of the hormone cortisol. Symptoms may include obesity, thinning arms and legs, a rounded face, and increased fat around the neck. Some causes of Cushing's syndrome is from taking glucocorticoid hormones such as prednisone for inflammatory diseases. Treatment for Cushing's syndrome depends on the cause.
Huntington's disease is the result of degeneration of neurons in areas of the brain. Huntington's disease is an inherited disorder. Early symptoms include mood swings, apathy, depression, and anger uncharacteristic of the individual. Judgement, memory, and other cognitive functions may become impaired. Presymptomatic testing is available for individuals who have a family history of Huntington's disease. Treatment includes medication and therapy for symptoms.
Chronic fatigue syndrome is a debilitating and complex disorder characterized by profound fatigue that lasts 6 months or longer, is not improved by bed rest, and may be worsened by physical or mental activity.
Drug addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
Obsessive compulsive disorder (OCD) is an anxiety disorder that causes a person to suffer repeated obsessions and compulsions. Symptoms include irresistible impulses despite a person's realization that the thoughts are irrational, excessive hand washing, skin picking, lock checking, or repeatedly rearranging items. People with OCD are more likely to develop trichotillomania, muscle or vocal tics, or an eating disorder. Treatment for OCD includes psychotherapy, behavioral therapy, and medication.
Antisocial personality disorder (ASPD) has many symptoms, signs, and causes. Therapy is one treatment option for antisocial personality disorder. It is closely related to other personality disorders (PD), such as borderline personality disorder and narcissistic personality disorder.
Grief is the feeling one experiences after a loss (of a friendship, death of loved one, job). Complicated grief refers to grief that lasts for more than a year. Mourning describes the customs and rituals that help a bereaved individual make sense of their loss.
ADHD afflicts approximately 3 percent to 5 percent of school-age children and an estimated 60 percent of those maintain the disorder into adulthood. Symptoms of adult ADHD include chronic lateness, anxiety, low self esteem, employment problems, difficulty controlling anger, impulsiveness, poor organization skills, procrastination, chronic boredom among others.
Attention deficit hyperactivity disorder (ADHD) is a behavioral disorder characterized by the symptoms hyperactivity, impulsivity, and inattention. Treatment for ADHD may involve behavioral therapy and psychostimulant or antidepressant medication.
Insomnia is the perception or complaint of inadequate or poor-quality sleep because of difficulty falling asleep; waking up frequently during the night with difficulty returning to sleep; waking up too early in the morning; or unrefreshing sleep. Secondary insomnia is the most common type of insomnia. Treatment for insomnia include lifestyle changes, cognitive behavioral therapy, and medication.
Psychotic disorders are a group of serious illnesses that affect the mind. Different types of psychotic disorders include schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, shared psychotic disorder, delusional disorder, substance-induced psychotic disorder, paraphrenia, and psychotic disorders due to medical conditions.
Seasonal affective disorder is a type of depression that tends to occur as the days grow shorter in the fall and winter. Symptoms of seasonal affective disorder include tiredness, fatigue, depression, irritability, body aches, poor sleep and overeating.
Fatigue can be described in various ways. Sometimes fatigue is described as feeling a lack of energy and motivation (both mental and physical). The causes of fatigue are generally related to a variety of conditions or diseases for example, anemia, mono, medications, sleep problems, cancer, anxiety, heart disease, drug abuse, and more. Treatment of fatigue is generally directed toward the condition or disease that is causing the fatigue.
During the ECT procedure, an electric current is passed through the brain to
produce controlled convulsions (seizures).
Why is electroconvulsive therapy performed?
ECT is useful for certain patients with significant depression,
particularly for those who cannot take or are not responding to antidepressants,
have severe depression, or are at a high risk for suicide. ECT often is
effective in cases where antidepressant medications do not provide sufficient
relief of symptoms.
How does electroconvulsive therapy work?
This procedure probably works by a
massive neurochemical release in the brain due to the controlled seizure. Highly
effective, ECT relieves depression within 1 to 2 weeks after beginning
treatments. After ECT, some patients will continue to have maintenance ECT,
while others will return to antidepressant medications.
