Aging: The process of becoming older, a process that is genetically determined and environmentally modulated. See the entire definition of Aging
Alzheimer's disease: A progressive neurologic disease of the brain that leads to the irreversible loss of neurons and dementia. The clinical hallmarks of Alzheimer's disease are progressive impairment in memory, judgment, decision making, orientation to physical surroundings, and language. A working diagnosis of Alzheimer disease is usually made on the basis of the neurologic examination. A definitive diagnosis can be made only at autopsy. On a cellular level, Alzheimer's disease is characterized by unusual helical protein filaments in nerve cells (neurons) of the brain. These odd twisted filaments are called neurofibrillary tangles. On a functional level, there is degeneration of the cortical regions, especially the frontal and temporal lobes, of the brain. See the entire definition of Alzheimer's disease
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
Assisted living: A type of long-term care facility for elderly or disabled people who are able to get around on their own but who may need help with some activities of daily living, or simply prefer the convenience of having their meals in a central cafeteria and having nursing staff on call.
Bladder: Any pouch or other flexible enclosure that can hold liquids or gases but usually refers to the hollow organ in the lower abdomen that stores urine -- the urinary bladder. The kidneys filter waste from the blood and produce urine, which enters the bladder through two tubes called ureters. Urine leaves the bladder through another tube, the urethra. In women, the urethra is a short tube that opens just in front of the vagina. In men, it is longer, passing through the prostate gland and then the penis. Infection of the bladder is called cystitis.
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."
Caffeine: A stimulant found naturally in coffee beans, tea leaves, cocoa beans (chocolate) and kola nuts (cola) and added to soft drinks, foods, and medicines. A cup of coffee has 100-250 milligrams of caffeine. Black tea brewed for 4 minutes has 40-100 milligrams. Green tea has one-third as much caffeine as black tea. See the entire definition of Caffeine
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
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
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
Contrast: Short for "contrast media." Contrast media are X-ray dyes used to provide contrast, for example, between blood vessels and other tissue.
Dehydration: Excessive loss of body water. Diseases of the gastrointestinal tract that cause vomiting or diarrhea may, for example, lead to dehydration. There are a number of other causes of dehydration including heat exposure, prolonged vigorous exercise (e.g., in a marathon), kidney disease, and medications (diuretics). See the entire definition of Dehydration
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
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
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
Hospice: A program or facility that provides special care for people who are near the end of life and for their families. Hospice care can be provided at home, in a hospice or another freestanding facility, or within a hospital. See also: Hospice care.
Incontinence: Inability to control excretions. Urinary incontinence is inability to keep urine in the bladder. Fecal incontinence is inability to retain feces in the rectum.
Medicaid: State programs of public assistance to persons regardless of age whose income and resources are insufficient to pay for health care. The United States federal government provides matching funds to the state Medicaid programs.
Medical history:1. In clinical medicine, the patient's past and present which may contain clues bearing on their health past, present, and future. The medical history, being an account of all medical events and problems a person has experienced, including psychiatric illness, is especially helpful when a differential diagnosis is needed. 2. The history of medicine.
Medicare: The United States government's health insurance program for:
"senior citizens" -- people 65 years of age or older,
certain younger people with specific disabilities, and
people with end-stage renal disease (ESRD) -- permanent kidney failure requiring dialysis or a transplant.
Motor: In medicine, having to do with the movement of a part of the body. Something that produces motion or refers to motion. For example, a motor neuron is a nerve cell that conveys an impulse to a muscle causing it to contract. The term "motor" today is also applied to a nerve that signals a gland to secrete. Motor is as opposed to sensory.
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.
NIH: The National Institutes of Health. The NIH is an important U.S. health agency. It is devoted to medical research. Administratively under the Department of Health and Human Services (HHS), the NIH consists of 20-some separate Institutes and Centers. NIH's program activities are represented by these Institutes and Centers. See the entire definition of NIH
Nursing: 1) Profession concerned with the provision of services essential to the maintenance and restoration of health by attending the needs of sick persons. 2) Feeding a infant at the breast.
Nursing home: A residential facility for persons with chronic illness or disability, particularly older people who have mobility and eating problems. Also called a convalescent home, long-term care facility.
Palliative care: 1) Medical or comfort care that reduces the severity of a disease or slows its progress rather than providing a cure. For incurable diseases, in cases where the cure is not recommended due to other health concerns, and when the patient does not wish to pursue a cure, palliative care becomes the focus of treatment. For example, if surgery cannot be performed to remove a tumor, radiation treatment might be tried to reduce its rate of growth, and pain management could help the patient manage physical symptoms. 2) In a negative sense, provision only of perfunctory health care when a cure is possible.
Primary care: The "medical home" for a patient, ideally providing continuity and integration of health care. All family physicians and most pediatricians and internists are in primary care. The aims of primary care are to provide the patient with a broad spectrum of care, both preventive and curative, over a period of time and to coordinate all of the care the patient receives.
Quality of life: An important consideration in medical care, quality of life refers to the patient's ability to enjoy normal life activities. Some medical treatments can seriously impair quality of life without providing appreciable benefit, while others greatly enhance quality of life.
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
Soothing: Bringing comfort, solace, reassurance, peace, composure, quietude. See the entire definition of Soothing
Stroke: The sudden death of some brain cells due to a lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain. A stroke is also called a cerebrovascular accident or, for short, a CVA. See the entire definition of Stroke
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
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.
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. The best way to treat dehydration is to prevent it from occurring.
Dementia is a significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. There are different criteria classification schemes for dementias such as cortical, subcortical, progressive, primary, and secondary dementias. Other conditions and medication reactions can also cause dementia. Dementia is diagnosed based on a certain set of criteria. Treatment for dementia is generally focused on the symptoms of the disease.
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).
Dysphagia or difficulty in swallowing, swallowing problems. Dysphagia is due to problems in nerve or muscle control. It is common, for example, after a stroke. Dysphagia compromises nutrition and hydration and may lead to aspiration pneumonia and dehydration.
Alzheimer's disease is a common cause of dementia. Symptoms and warning signs of Alzheimer's disease include memory loss, difficulty performing familiar tasks, disorientation to time and place, misplacing things, and more. The biggest risk factor for Alzheimer's disease is increased age. Treatment for Alzheimer's is often targeted toward decreasing the symptoms and progression of the disease.
A number of vital tasks carried out during sleep help maintain good health and enable people to function at their best. Sleep needs vary from individual to individual and change throughout your life. Not getting enough sleep can hurt memory performance, health, and your mood.
Hypothermia is having a body core temperature of less than 35 C or 95 F. Most causes of hypothermia are preventable. Risk factors for hypothermia include age, mental status, medical conditions, and medications. Symptoms of hypothermia generally depend upon the severity of the condition. Treatment depends upon the severity of hypothermia. If not treated early, hypothermia can lead to cardiac arrest, coma, or death.
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.
Insomnia is difficulty in falling or staying asleep, the absence of restful sleep, or poor quality of sleep. Insomnia is a symptom and not a disease. The most common causes of insomnia are medications, psychological conditions, environmental changes and stressful events. Treatments may include non-drug treatments, over-the-counter medicines, and/or prescription medications.
Brain lesions (lesions on the brain) are caused by trauma, inflammation, autoimmune diseases, cancers, other diseases, stroke, bleeding, pituitary adenomas, and cerebral palsy. Symptoms of brain lesions include headache, nausea, fever, neck pain and stiffness, affected vision and speech, weakness or paralysis to one side of the body. Diagnosis of brain lesions is generally with imaging studies like CT or MRI scans. Treatment and prognosis of brain lesions depends on the cause of the lesion.
Regular physical activity can reduce the risk of disease. Regular exercise can also reduce the symptoms of stress and anxiety. There are fitness programs that fit any age or lifestyle.
Bowel or fecal incontinence refers to the loss of voluntary control of stool, or bowel movements. The condition can include partial incontinence, in which a person loses only a small amount of liquid waste, to complete incontinence, in which the entire bowel movement cannot be controlled. Diet changes and elimination of certain medications can help patients to regain bowel control. Treatment involves a combination of medication, biofeedback, and exercise.
Millions of women suffer from urinary incontinence (UI). UI occurs twice as often in women as in men. There are many types of urinary incontinence: stress incontinence, urge incontinence, overactive bladder, functional incontinence, overflow incontinence, transient incontinence, and mixed incontinence.
Most often, caregivers take care of other adults who are ill or disabled. Less often, caregivers are grandparents raising their grandchildren. The majority of caregivers are middle-aged women. Caregiving can be very stressful, so it's important to recognize when it's putting to much strain on you and to take steps to prevent/relieve stress.
Depression in the elderly is very common. That doesn't mean, though, it's normal. Treatment may involve antidepressants, psychotherapy, or electroconvulsive therapy.
Alzheimer's disease can be not only mentally devastating to an indivdiual and family, it can also be emotionally devastating. Preparing financially for someone with Alzheimer's disease is an important task to complete so that bills get paid and the best coverage is provided. Learn what Medicade and Medicare will provide for a patient.
Depressive disorders have been with mankind since the beginning of recorded history. In the Bible, King David, as well as Job, suffered from this affliction. Hippocrates referred to depression as melancholia, which literally means black bile. Black bile, along with blood, phlegm, and yellow bile were the four humors (fluids) that described the basic medical physiology theory of that time. Depression, also referred to as clinical depression, has been portrayed in literature and the arts for hundreds of years, but what do we mean today when we refer to a depressive disorder? In the 19th century, depression was seen as an inherited weakness of temperament. In the first half of the 20th century, Freud linked the development of depression to guilt and conflict. John Cheever, the author and a modern sufferer of depressive disorder, wrote of conflict and experiences with his parents as influencing his development of depression.
