Mild Cognitive Impairment in Parkinson's Disease
Mild Cognitive Impairment in Parkinson's Disease
Mild cognitive impairment, including difficulty with solving problems, planning, attention,
 or recalling information, can be a significant problem for individuals with Parkinson's
 disease. Even mild cognitive difficulties can lead to worse functioning, quality of life,
 depression, and difficulty for caregivers. Thus, ideally treatment at this stage would
 improve both cognitive symptoms and some of the other problems associated with these
 symptoms.

 Despite the fact that mild cognitive impairment is a serious problem for Parkinson's disease
 patients little is known about how best to treat it. This study is a 24-week clinical trial
 to see if a Food and Drug Administration (FDA)-approved drug, the Exelon (rivastigmine)
 Patch, is useful in treating mild cognitive impairment in patients with Parkinson's disease.
 Currently, the Exelon (rivastigmine) Patch is FDA-approved for the treatment of mild to
 moderate dementia in Alzheimer and Parkinson's disease patients.
This study has 2 phases. Each phase will last 10 weeks and there will be a 4-week break
 between the 2 phases. Thus, you will be enrolled in the study for a total of 24 weeks. Over
 the course of the 24-week period we will schedule to see you in-person 6 times and check-in
 with you on the telephone 4 times, 2 times during each phase.

 Phase I

 Screening (may be the same day as the baseline visit) - Research personnel will determine if
 you are eligible to participate in this study.

 Visit 1 - Baseline Visit, Start Study Medication

 Phone Call 1 - Check in to see how you are feeling after starting the study medication

 Visit 2 - 4 Weeks after Baseline, Increase Study Medication if tolerated

 Phone Call 2 - Check in to see how you are feeling after increasing the study medication

 Visit 3/ Phase I Termination Visit - 10 Weeks after Baseline (Phase I Termination Visit)

 4 Week Break (no study medication)

 Phase II

 Visit 4/ Phase II Baseline - 14 Weeks after Baseline, Start Study Medication

 Phone Call 3 - Check in to see how you are feeling after starting the study medication

 Visit 5 - 18 Weeks after Baseline, Increase Study Medication

 Phone Call 4 - Check in to see how you are feeling after increasing the study medication

 Visit 6/Phase II and Study Termination Visit - 24 Weeks after Baseline

 Visits 1, 3, 4, and 6 will last for about 2 ½ hours and visits 2 and 5 about 30 minutes. The
 'check in' phone calls will last approximately 5-10 minutes.

 After 24 weeks, your study participation will be over.
