1. Alzheimer's disease
alzheimer's disease is a form of senile dementia of unknown origin that has characteristic pathologic changes in the brain. Its onset is slow and at an earlier age than the common dementia. After onset, it progresses steadily and the pathology is more severe than the average form of senile dementia. Most studies report that this disease is responsible for the cognitive decline in about 50% of demented older adults.

2. Alzheimer's disease (AD)
A progressive, neurodegenerative disease characterized by loss of function and death of nerve cell s in several areas of the brain leading to loss of cognitive function such as memory and language. The cause of nerve cell death is unknown. alzheimer's disease is the most common cause of dementia .

3. Beta-amyloid
The protein which forms thick deposits, or plaques, in the brains of people with alzheimer's disease, a disease where memory skills gradually deteriorate with age.

4. Bovine spongiform encephalitis (BSE, bovine spongiform encephalopathy)
A neuro-degenerative disease found in domestic cattle which is related to a number of other similar diseases found in other animal species, including humans. The most well-known of these other diseases are scrapie, found in sheep, and Creutzfeldt-Jakob Disease , found in humans. The family of diseases is caused by an abnormally-configured protein called a prion . The function of the protein in its normal configuration is not certain. The diseases are similar to alzheimer's disease in humans, except the progressive loss of brain function is more rapid.

5. Calcium channel blocker
A drug that blocks the entry of calcium into cells, thereby preventing cell dealth and loss of function caused by excess calcium. Calcium channel blockers are used primarily to lower blood pressure and to treat certain heart conditions and stroke, but are being studied as potential treatments for alzheimer's disease .

6. Choline acetyltransferase (CAT)
An enzyme that controls the production of acetylcholine ; appears to be depleted in the brains of alzheimer 's patients.

7. Cholinergic system
The system of nerve cells that uses acetylcholine as its neurotransmitter ; nerve cells in the cholinergic system are damaged in the brains of alzheimer 's patients.

8. Dementia
Dementia is clinical syndrome characterized by the organic loss of intellectual functioning, such as impairment of orientation, memory, comprehension, calculation, learning capacity and judgment. The DSM of the American Psychiatric Association has a summary of diagnostic criteria for dementia. The prevalence of dementia increases with age, starting with 1 percent at age 60, and double the rate every 5 years. alzheimer's disease is associated with dementia.

9. Down's syndrome (Down syndrome, Trisomy 21)
Physical characteristics of a person with Down's syndrome include small and short head, flat nasal bridge, reddish cheeks, dry lips, large, protruding tongue, small ears, epicanthal folds, and short neck. Mental retardation and hypotonia are also major symptoms, the degree of which varies with individuals. There is also a high incidence of congenital heart diseases and duodenal atresia . With good support, persons with this syndrome can develop their full potential. An alzheimer -like dementia often occurs in the fourth and fifth decades and leads to a shortened life expectancy. The chromosomal abnormality is diagnostic. In 95% of cases, trisomy 21 is present (one extra chromosome 21), and in the rest which has the usual 46 chromosomes present, there is an abnormal translocation involving chromosome 21.

10. Geriatric medicine
This medical field deals with the study and treatment of illnesses and disorders that mainly affect elderly people (e.g., arthritis , alzheimer's disease , etc.)
