Although current medications cannot cure Alzheimer’s or stop it from progressing, they may help lessen symptoms, such as memory loss and confusion, for a limited time.
The U.S. Food and Drug Administration (FDA) has approved two types of medications — cholinesterase inhibitors (Aricept, Exelon, Razadyne, Cognex) and memantine (Namenda) — to treat the cognitive symptoms (memory loss, confusion, and problems with thinking and reasoning) of Alzheimer's disease.
As Alzheimer’s progresses, brain cells die and connections among cells are lost, causing cognitive symptoms to worsen. While current medications cannot stop the damage Alzheimer’s causes to brain cells, they may help lessen or stabilize symptoms for a limited time by affecting certain chemicals involved in carrying messages among the brain's nerve cells. Doctors sometimes prescribe both types of medications together. Some doctors also prescribe high doses of vitamin E for cognitive changes of Alzheimer's disease.
