  Purpose

The purpose of this study is to investigate the organization of memory and develop future methods for early detection of AD. Using functional magnetic resonance imaging (fMRI), we examine the responsiveness of the brain to memory tasks, specifically focusing on regions of the brain (the mesial temporal lobe and posterior cingulate) that are known to be involved in early stages of Alzheimer's disease (AD). Of interest are differences in brain activation between people with and without a family history of AD and other risk factors.

Study Population

Persons with a parent with Alzheimer's disease will be recruited from the Wisconsin Registry for Alzheimer's Prevention (WRAP). Persons with MCI will be recruited from the UW clinics and satellite clinics. Controls for the above study groups will be recruited from the WRAP and the local community.

Criteria

Inclusion Criteria:

  • MCI Group: Diagnosis of mild cognitive impairment
  • AD Family History Group: Confirmed family history of Alzheimer's and concurrent enrollment in the Wisconsin Registry for Alzheimer's Prevention (WRAP)
  • Control Groups: Cognitively healthy and both parents survived past age 70 with no memory problems

Exclusion Criteria:

  • Claustrophobia
  • Metallic or electronic implants or devices that are not MRI-safe
