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
Analgesia: The inability to feel pain while still conscious. From the Greek an-, without + algesis, sense of pain.
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."
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.
Cardiopulmonary: Having to do with both the heart and lungs.
Cast: 1) A protective shell of fiberglass, plastic, or plaster, and bandage that is molded to protect broken or fractured limb(s) as it heals. 2) An abnormal mass of dead cells that forms in a body cavity. For example, cases of cells that form in the tubules of the kidneys are sometimes detected in urine samples.
Coma: A state of deep unarousable unconsciousness. See the entire definition of Coma
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
Durable power of attorney: This is a type of advance medical directive in which legal documents provide the power of attorney to another person in the case of an incapacitating medical condition. See the entire definition of Durable power of attorney
Gastrostomy: A surgical opening into the stomach. This opening may be used for feeding usually via a feeding tube called a gastrostomy tube. This can also be done by percutaneous endoscopic gastrostomy (PEG). PEG is a surgical procedure for placing a feeding tube but does not necessitate doing an open laparotomy (operation on the abdomen). The aim of PEG (as with any gastrostomy) is to feed those who cannot swallow. PEG may be done by a. surgeon, otolaryngologist (ENT specialist) or gastroenterologist (GI specialist). It is done in a. hospital or outpatient surgical facility. Local anesthesia (usually lidocaine or another spray) is used to anesthetize the throat. An endoscope (a flexible, lighted instrument) is passed through the mouth, throat and esophagus to the stomach. The surgeon then makes a small incision (cut) in the skin of the abdomen and pushes an intravenous cannula (an IV tube) through the skin into the stomach and sutures (ties) it in place. The patient can usually go home the same day or the next morning. Possible complications include wound infection (as in any kind of surgery) and dislodging or malfunction of the tube. Percutaneous endoscopic gastrostomy may be a mouthful (as a term) but it describes the procedure accurately. A gastrostomy (a surgical opening into the stomach) is made percutaneously (through the skin) using an endoscope to put the feeding tube in place. PEG, when feasible, takes less time, carries less risk and costs less than a classic surgical gastrostomy which requires opening the abdomen.
Incurable: Not amenable to a cure. Incapable of being cured, healed and made well again. Many pancreatic cancers are incurable. From the word cure, from the Latin cura meaning care, concern or attention.
Injury: Harm or hurt. The term "injury" may be applied in medicine to damage inflicted upon oneself as in a hamstring injury or by an external agent on as in a cold injury. The injury may be accidental or deliberate, as with a needlestick injury. The term "injury" may be synonymous (depending on the context) with a wound or with trauma.
Life-support: Pertaining to life support, as in "He is only here because of the life-support systems.
Living will: A living will is one form of advance medical directive. Advance medical directives pertain to treatment preferences and the designation of a surrogate decision-maker in the event that a person should become unable to make medical decisions on their own behalf. See the entire definition of Living will
Mechanical ventilation: Use of a machine called a ventilator or respirator to improve the exchange of air between the lungs and the atmosphere.
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.
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.
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.
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
Patient autonomy: The right of patients to make decisions about their medical care without their health care provider trying to influence the decision. Patient autonomy does allow for health care providers to educate the patient but does not allow the health care provider to make the decision for the patient.
Percutaneous: Through the skin, as in a percutaneous biopsy.
Rehabilitation: The process of restoration of skills by a person who has had an illness or injury so as to regain maximum self-sufficiency and function in a normal or as near normal manner as possible. For example, rehabilitation after a stroke may help the patient walk again and speak clearly again. See the entire definition of Rehabilitation
Resuscitate: To restore to life. Derived from the Latin resuscitare, to reawaken.
Ventilation: The exchange of air between the lungs and the atmosphere so that oxygen can be exchanged for carbon dioxide in the alveoli (the tiny air sacs in the lungs). See the entire definition of Ventilation
A stroke results from impaired oxygen delivery to brain cells via the bloodstream. A stroke is also referred to as a CVA, or cerebrovascular incident. Symptoms of stroke include: sudden numbness or weakness of the face, arm or leg. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, or loss of balance, and/or sudden severe headache with no known cause. A TIA, or transient ischemic attack is a short-lived temporary impairment of the brain caused by loss of blood supply. Stroke is a medical emergency.
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.
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.
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.
Coma is the inability to waken or react to the surrounding environment. The Glasgow Coma Scale is frequently used to measure the depth of coma. Causes of coma include trauma, bleeding, edema, lack of oxygen, poisoning, or hypoglycemia. Prognosis for a patient in a coma depends on the cause of the coma.
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.
impairment in another area of thinking such as the ability to organize thoughts and reason, the ability to use language, or the ability to see accurately the visual world (not because of eye disease), and
these impairments are severe
enough to cause a decline in the patient's usual level of functioning.
Although
some kinds of memory loss are normal parts of aging, the changes due to aging
are not severe enough to interfere with the level of function. Many different
diseases can cause dementia, but Alzheimer's disease is by far the most common
cause for dementia in the United States and in most countries in the world.
What is Alzheimer's disease?
Alzheimer's disease (AD) is a slowly progressive disease of the brain that is
characterized by impairment of memory and eventually by dist...
