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.
Adult ADHD:Attention deficit hyperactivity disorder (ADHD) as found in the adult population. ADHD is a well-known childhood disorder that is characterized by varying degrees of hyperactivity, impulsivity, and/or inattention that lead to difficulty in academic, emotional, and social functioning. Children who are diagnosed with ADHD may continue to exhibit symptoms that persist into adulthood. In the 1970s, the condition began to be diagnosed in adults who never received the diagnosis as children but displayed many of the characteristic symptoms. While up to 5% of school-aged children are believed to have ADHD, its prevalence in the adult population is difficult to estimate, but is likely to be in the range of 1%-5% of the population. Symptoms of ADHD in adults can include difficulty following directions, problems information, difficulty with concentration, and trouble with organizing tasks or completing work within time limits. Treatment, as in the pediatric population, can involve both behavioral therapies and medications.
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.

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
Breathing: The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction, and then exhaled due to muscle relaxation.
Chronic: This important term in medicine comes from the Greek chronos, time and means lasting a long time. See the entire definition of Chronic
Cognitive: Pertaining to cognition, the process of knowing and, more precisely, the process of being aware, knowing, thinking, learning and judging. The study of cognition touches on the fields of psychology, linguistics, computer science, neuroscience, mathematics, ethology and philosophy. See the entire definition of Cognitive
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
EEG: Electroencephalogram, e technique for studying the electrical current within the brain. Electrodes are attached to the scalp. Wires attach these electrodes to a machine which records the electrical impulses. The results are either printed out or displayed on a computer screen. Electroencephalogram is abbreviated EEG. See the entire definition of EEG
Family history: The family structure and relationships within the family, including information about diseases in family members. See the entire definition of Family history
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
Food and Drug Administration: The FDA, 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 Food and Drug Administration
Genetic: Having to do with genes and genetic information.
Hyperactivity: A higher than normal level of activity. An organ can be described as hyperactive if it is more active than usual. Behavior can also be hyperactive. See the entire definition of Hyperactivity
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.
Indication:1. In medicine, a condition which makes a particular treatment or procedure advisable. CML (chronic myeloid leukemia) is an indication for the use of Gleevec (imatinib mesylate). 2. A sign or a circumstance which points to or shows the cause, pathology, treatment, or outcome of an attack of disease. The presence of the Philadelphia chromosome in peripheral blood cells is an indication of a relapse in CML.
Learning disability: A childhood disorder characterized by difficulty with certain skills such as reading or writing in individuals with normal intelligence. Learning disorders affect the ability to interpret what one sees and hears or the ability to link information from different parts of the brain. These limitations can show up in many ways -- as specific difficulties with spoken and written language, coordination, self-control, or attention. Such difficulties extend to schoolwork and can impede learning to read or write, or to do math. See the entire definition of Learning disability
Neurological: Having to do with the nerves or the nervous system.
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
Outlet: The exit or opening. The means by which something escapes.
Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts. They include the superscription or heading with the symbol "R" or "Rx", which stands for the word recipe (meaning, in Latin, to take); the inscription, which contains the names and quantities of the ingredients; the subscription or directions for compounding the drug; and the signature which is often preceded by the sign "s" standing for signa (Latin for mark), giving the directions to be marked on the container.
Prevalence: The proportion of individuals in a population having a disease. Prevalence is a statistical concept referring to the number of cases of a disease that are present in a particular population at a given time.
Psychiatric: Pertaining to or within the purview of psychiatry, the medical specialty concerned with the prevention, diagnosis, and treatment of mental illness. See the entire definition of Psychiatric
Remission: Disappearance of the signs and symptoms of cancer or other disease. When this happens, the disease is said to be "in remission." A remission can be temporary or permanent.
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.
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
Substance:1. Material with particular features, as a pressor substance. 2. The material that makes up an organ or structure. Also known in medicine as the substantia. 3. A psychoactive drug as, for example, in substance abuse.
Substance abuse: The excessive use of a substance, especially alcohol or a drug. (There is no universally accepted definition of substance abuse.) See the entire definition of Substance abuse
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.
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.
Depression is an illness that involves the body, mood, and thoughts and affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. The principal types of depression are major depression, dysthymia, and bipolar disease (also called manic-depressive disease).
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.
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.
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.
Learning disabilities can cause an individual to have trouble learning and using skills such as reading, listening, writing, reading, speaking, reasoning, and performing mathematics. There is no cure for learning disabilities. Parents and teachers working together to properly diagnose learning disabilities can properly plan a course of education. For some, medication may be appropriate as complimentary treatment.
Stress may be considered as any physical, chemical, or emotional factor that causes bodily or mental unrest and that may be a factor in disease causation. An important goal for those under stress is the management of stress in our lives. Elimination of stress is unrealistic, since stress is a part of normal life. We can however, learn to manage stress through techniques such as exercise, relaxation, meditation, time management, and support systems so that we have control over our stress and its effects on our physical and mental health.
Attention deficit hyperactivity disorder (ADHD) can be challenging for a parent or caregiver with a child with this disorder. There are steps, routines, and help for parents and caregivers of children with ADHD to help guide the family toward a productive and healthy life.
Early warning signs of job stress include headache, sleep disturbance, difficulty in concentrating, short temper, upset stomach, job dissatisfaction, and low morale. Stress on the job can be damaging to your health in that job stress is the outcome when job demands cannot be met.
Generalized anxiety disorder (or GAD) is characterized
by excessive, exaggerated
anxiety and worry about everyday life events with no obvious reasons for
worry. People with
symptoms of generalized anxiety disorder tend to always expect disaster and
can't stop worrying about health, money, family, work, or school. In people
with GAD, the worry often is unrealistic or out of proportion for the
situation. Daily life becomes a constant state of worry, fear, and dread.
Eventually, the anxiety so dominates the person's thinking that it interferes
with daily functioning, including work, school, social activities, and
relationships.
What Are the Symptoms of GAD?
GAD affects the way a person thinks, but the anxiety can lead to physical
symptoms, as well. Symptoms of GAD can include:
