Study Summary

This study will evaluate the safety and effectiveness of donepezil (Aricept) for treating mild dementia in patients with Parkinson's disease. Donepezil is approved for treating patients with Alzheimer's disease, whose memory and cognition problems are similar to those of patients with Parkinson's disease who are affected by dementia. Donepezil prevents the breakdown of a chemical messenger called acetylcholine, which is involved in memory and other cognitive functions, and may improve cognition in patients. Patients 40 years of age and older with Parkinson's disease who have mild to moderate dementia may be eligible for this 6-month study. It involves 6 clinic visits of approximately 2 hours each, described below. Candidates will be screened for participation during Visit 1. * Visit 1 (screening visit): Study candidates will have a medical history, physical and neurological examinations, electrocardiogram (EKG), and possibly blood tests. They will also undergo neuropsychological testing (tests of memory, language, mood and, other brain functions) and fill out a quality of life questionnaire. Those enrolled will be randomly assigned to receive either donepezil (5 mg per day) or placebo-a look-alike pill with no active ingredients. After 4 weeks, the dose of donepezil will be increased to 10 mg per day. Patients who do not tolerate the higher dose will have it reduced to 5 mg. Those who do not tolerate the 5-mg dose will be taken off medication but will continue to be followed and tested. * Visit 2 (week 7): Patients will have a neurological examination and neuropsychological testing and will fill out a quality of life questionnaire. * Visit 3 (week 10): Patients will repeat the evaluations done during visit 2 and will stop taking the study medication. * Visit 4 (week 16): Patients will repeat the evaluations done during visit 2 and will have their study medication switched. That is, patients previously on placebo will be switched to donepezil, and patients who were
