The Vossel lab is recruiting participants for the study ADRC-BIND (Alzheimer's Disease Research Center - Biomarkers in Neurodegenerative Disease). ADRC-BIND is the main observational study supporting various research projects within the Mary S. Easton Center for Alzheimer's Disease Research at UCLA (Director, Keith Vossel, MD, MSc). The purpose of ADRC-BIND is to collect a large amount of information from tests of brain function and cognitive performance over a period of time to help researchers learn more about and develop new therapies for neurodegenerative diseases. This study seeks to enroll participants willing to undergo cognitive testing, brain imaging (PET and MRI), blood draws, optional lumbar puncture, and an overnight sleep study. Eligible participants may have normal cognition or be diagnosed with mild cognitive impairment, Alzheimer’s disease, dementia with Lewy bodies, Parkinson’s disease with dementia, frontotemporal dementia, transient epileptic amnesia, or adult-onset epilepsy. Participants will be evaluated for as long as they are willing and able to participate.
