Laura Murray
Primary Investigator
Overview
The purpose of this study is to see how much brain activity changes over a short period of time (i.e., within a week, and within two months) in people with dementia using MRI scanning.
Description
The purpose of this study is to investigate the test-retest reliability of fMRI word retrieval paradigms in individuals with dementia and age- education-matched normal controls.
