There is currently no cure for Alzheimer's disease or for most other causes of dementia. Nor can a cure be expected in the foreseeable future. Researchers are still at the stage of developing drugs that will slow down the progression of the disease, at least in some cases. They still do not know how to prevent the disease from occurring, how to stop its progression, or how to reverse its effects. It is hoped that more research into the causes of Alzheimer's disease will eventually make a cure possible.
