Tacrine and donepezil hydrochloride are called acetylcholinesterase inhibitors because they decrease the breakdown of acetylcholine. Although these drugs can help to improve memory, they do not stop the brain cell deterioration caused by Alzheimer's disease. Other drugs that are believed to enhance communication between nerve cells are in the developmental stage. Start by contacting your physician or a doctor who specializes in Alzheimer's or geriatrics. It is quite possible that your physician can prescribe medication to counteract some of the symptoms such as depression, agitation and sleeplessness.
Physicians are also a good referral source for available community services and resources.
