Clinical Core

Physician with patientGoals and Activities:

  • Assemble and follow a well-characterized diverse group of normal and cognitively impaired participants with standardized medical, neurologic, and neuropsychological evaluations.
  • Facilitate the acquisition of biospecimens (blood and CSF), sensory and motor data, brain imaging and novel biomarkers from the participants.
  • Provide participants and data to Duke and UNC investigators and the national Alzheimer’s disease research community for further investigation.

Diverse group of smiling people, young and old.Join Our Study:

The Duke-UNC Alzheimer’s Disease Research Center’s Memory & Aging Study works to identify the biological factors involved in normal brain aging and disease with the help of a diverse group of young and older people with and without memory impairments.
