To be effective, the spermicide must be placed deep in the vagina, close to the cervix. Creams, gels, and foams are squirted into the vagina using an applicator.

Causes of Alzheimer's disease. Alzheimer's disease is caused by parts of the brain wasting away (atrophy), which damages the structure of the brain and how it works.
Alzheimer's disease is the most common cause of dementia â a group of brain disorders that cause the loss of intellectual and social skills. In Alzheimer's disease, the brain cells degenerate and die, causing a steady decline in memory and mental function. Current Alzheimer's disease medications and management strategies may temporarily improve symptoms. This can sometimes help people with Alzheimer's disease maximize function and maintain independence for a little while longer.
