Summary
Alzheimer's disease is a medical illness that damages the brain and causes problems with
memory, mood and behavior. A substance called acetylcholine (ACh), which is naturally
produced in the body, plays an important role in the normal functioning of the brain. In
subjects with Alzheimer's disease, the level of ACh is greatly reduced. Currently, there are
three commonly prescribed drugs used for treating the symptoms of Alzheimer's disease by
helping to maintain the level of ACh in the brain. This study will evaluate how much each of
these drugs changes the levels of certain brain chemicals that are known to, or may play an
important role in, Alzheimer's disease and its symptoms.
