What is alzheimers?

Alzheimer's disease (AD) is the most common form of dementia among older people. Dementia is a brain disorder that seriously affects a person's ability to carry out daily activities. AD begins slowly. It first involves the parts of the brain that control thought, memory and language. People with AD may have trouble remembering things that happened recently or names of people they know. Over time, symptoms get worse. People may not recognize family members or have trouble speaking, reading or writing. They may forget how to brush their teeth or comb their hair. Later on, they may become anxious or aggressive, or wander away from home. Eventually, they need total care. This can cause great stress for family members who must care for them.

Alzheimer's disease

Alzheimer's disease is the most common form of dementia, which describes the loss of mental abilities, such as memory and reasoning.


Alzheimer's disease

Alzheimer's disease is a slowly progressive, irreversible brain disease that results in memory loss, impaired thinking ability, and ultimately changes in behavior or personality. The symptoms of Alzheimer's disease progress over time from mild forgetfulness to severely impaired mental function. These symptoms result from the death of brain cells and the lost connections between them. The course of the disease, including the range of symptoms and the speed at which mental function declines, varies widely from individual to individual. People with Alzheimer's disease live an average of eight to ten years after diagnosis, but some may live for twenty years or more.


Alzheimer's disease

A form of presenile dementia due to atrophy of frontal and occipital lobes of the brain. Usually occurs between ages 40 and 60, more often in women than men. Involves progressive, irreversible loss of memory, deterioration of intellectual functions, apathy, speech and gait disturbances, and disorientation. Course may take from a few months to 4-5 years to progress to complete loss of intellectual function.


Alzheimer Disease

Alzheimer disease (AD) is the most common cause of dementia in industrialized nations. Dementia is a brain disorder that interferes with a person's ability to carry out everyday activities. The brain of a person with Alzheimer disease (see Multimedia file 1) has abnormal areas containing clumps (senile plaques) and bundles (neurofibrillary tangles) of abnormal proteins. These clumps and tangles destroy connections between brain cells.This usually affects the parts of the brain that control cognitive (intellectual) functions such as thought, memory, and language.Levels of certain chemicals that carry messages around the brain (neurotransmitters) are low.The resulting losses in intellectual ability are called dementia when they are severe enough to interfere with everyday functioning. Alzheimer disease affects mainly people aged 60 years or older. The risk of developing Alzheimer disease continues to increase with age. People aged 80 years, for example, have a significantly greater risk than people aged 65 years.About 5 million people in the United States and more than 30 million people worldwide have Alzheimer disease. Many others have mild, or minimal, cognitive impairment, which frequently precedes dementia.The number of people with Alzheimer disease is expected to rise substantially in the next few decades because of the aging of the population.The disease affects all races and ethnic groups.It seems to affect more women than men.Alzheimer disease is a progressive disease, which means that it gets worse over time. It cannot be cured or reversed by any known treatment. The symptoms often are subtle at first.Over time, people with the disease lose their ability to think and reason clearly, judge situations, solve problems, concentrate, remember useful information, take care of themselves, and even speak.Changes in behavior and personality are common.People with mild Alzheimer disease usually require close supervision and help with everyday tasks such as cooking, shopping, and paying bills.People with severe Alzheimer disease can do little on their own and require complete full-time care. Because of this, Alzheimer disease is considered a major public health problem. The cost of caring for people with the disease is estimated at over $100 billion per year in the United States. The average yearly cost per affected person is $20,000 to $40,000, depending on the severity of the disease.That cost doesn't take into account the loss of quality of life for the affected person, nor the physical and emotional toll on family caregivers.


Alzheimer's disease
Dementia is a loss of brain function that occurs with certain diseases. Alzheimer's disease (AD), is one form of dementia that gradually gets worse over time. It affects memory, thinking, and behavior. Memory impairment, as well as problems with language, decision-making ability, judgment, and personality, are necessary features for the diagnosis.

Disease, Alzheimer's
Alzheimer's disease is a progressive and fatal brain disorder that gradually destroys a person's memory and ability to learn, reason, communicate, and make judgments.

Caregivers for Alzheimer's Disease
Caring for someone who has Alzheimer's disease (AD) can be stressful and overwhelming. It's important to take care of yourself. Ask for and accept help. Talk to the doctor. Find out what treatments might help control symptoms or address behavior problems. Find a support group. Others who have "been there" may be able to help and will understand.

Alzheimer's Disease Support
Being diagnosed with Alzheimer's disease does not mean that your life is over. Yes, you will have to deal with changes, some of which are very frustrating. But by taking care of yourself, preparing for the changes you will face, and spending time with family and friends doing activities you enjoy, you can continue to live a productive and meaningful life.

Intermediate Symptoms of Alzheimer's Disease
Alzheimer's disease is one of many causes of dementia, an impairment in memory and thinking that is severe enough to affect an individual's ability to function in daily life. Symptoms of Alzheimer's disease are subtle at first and may be identical to those associated with other causes of dementia. While this article is a guide to the symptoms associated with various stages of Alzheimer's disease, the diagnosis of the condition must be made by a doctor who can determine the exact cause of the symptoms and rule out other causes of dementia.

Alzheimer Disease in Individuals With Down Syndro
Alzheimer's disease (AD) is the most common form of dementia. The disease is progressive, and the brain degenerates. Alzheimer's disease is strongly associated with old age. However, it should not be considered a normal part of aging.

Alzheimer disease usually affects the parts of the brain that control cognitive (intellectual) functions such as thought, memory, and language.
