COMPASS-ND (The Comprehensive Assessment of Neurodegeneration and Dementia)

What is this Study about?

Compass-ND is a research study designed to assess individuals with different sorts of cognitive and movement changes seen in older adults. We will look at the usefulness of imaging studies, clinical assessments and biomarker tests, together with measurements of memory, thinking and daily functioning, for distinguishing these changes from each other and from healthy aging.
