Primary Outcome Measures:
  • Anatomic relationships during cognitive activity, and how these relationships change as a function of drug

Secondary Outcome Measures:
  • fMRI as a surrogate marker for drug efficacy

Estimated Enrollment: 26
Study Start Date: September 2004
Study Completion Date: October 2007
Detailed Description:
Donepezil HCI (Aricept®) is an FDA-approved drug now used to enhance memory in patients with Alzheimer's disease. The aim of this project is to examine the effects of Donepezil HCI (Aricept®) on memory induced brain activation patterns in the context of a double-blind, crossover trial of patients with multiple sclerosis (MS). We will perform task activation experiments involving two cognitive domains. The proposed work on MS patients should yield new information regarding functional anatomic relationships during cognitive activity, and how these relationships change as a function of drug treatment.

Ages Eligible for Study:   18 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:
