Although there are no drugs that can cure Alzheimer's disease, there are a number of drug treatments that can help some people with Alzheimer's disease.
The currently available treatments can slow down the progression of the disease in some cases for periods between 6 and 18 months. The main class of such compounds is the cholinesterase inhibitors.
Other kinds of drugs are sometimes useful for controlling some of the symptoms of Alzheimer's disease, such as sleeplessness and agitation. In general, however, the use of drugs such as sleeping pills or tranquillisers should be kept to a minimum if someone has Alzheimer's disease, as they can cause increased confusion.
