Alzheimer’s is a degenerative disease of nerve cells in the cerebral cortex that leads to atrophy of the brain and senile dementia. First described in 1906, the disease is characterized by abnormal accumulation of plaques and malformed nerve cells. The disease usually affects people over age 65; short-term memory loss is an early symptom. The cause of Alzheimer’s is not known, and, as yet, there is no known cure.
