Alzheimer Disease

Alzheimer Disease is the progressive destruction and death of nerve cells in the brain, which ultimately causes decline in mental function. Proteins in the brain, because of aging, accumulate in clusters and tangles (Neurofibrillary Tangles) in the hippocampus and cerebral cortex. Researchers are unsure whether these plaques (Amyloid Plaques) in the brain cause Alzheimers, or whether they are a product of the disorder.

Synmptoms of Alzheimers :
Symptoms of Alzheimer can be split into two main categories: Cognitive, and Behavioral.

Cognitive Symptoms Include:
Memory loss
hard to reason

Behavioral Symptoms Include:
Delusions and helucinations

There are no known cures for this disorder; only drugs that slow down the progression of the disease. Alzheimers is a very difficult disease to deal with, because researchers don't fully understand it. In fact, a conclusive diagnosis can only be made after death, in an autopsy of the brain.

Alzheimer Disease is very common, and age is a major risk factor. As many as 4 million Americans have Alzheimers, and 10% of people over 65 have the disease.

There are two different types of Alzheimer Disease--Sporadic Alzheimer Disease, and Familiar Alzheimer Disease. Sporadic AD is the type that most people have. This type, has no obvious pattern of inheritance. But Familiar AD is an inherited disease. Less than 10% of patients with AD have this type.
