Effects of Mental Stimulation in Patients With Mild Cognitive Impairment

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to learn if activities that challenge the brain (mentally stimulating activities) can improve memory and other types of thinking in patients with Mild Cognitive Impairment. The study will compare the effects of different methods of mental stimulation.
