Definitions for "Alzheimer’s disease"
(älts¹hì-merz), degenerative disease of the brain cells producing loss of memory and general intellectual impairment. It usually affects people over age 65, although it can appear earlier, especially in some familial forms of the disease. As the disease progresses, a variety of symptoms may become apparent, including confusion, irritability, and restlessness, as well as disorientation and impaired judgment and concentration. The cause is unknown, although there appears to be a genetic component; the excessive beta amyloid proteins and the traces of aluminum found in the brains of victims are being studied as possible contributors. There is no cure, but the drug tacrine provides temporary improvement for some patients. 1
