The Clinical Core provides standardized assessment of research participants, focusing especially on longitudinal changes in cognitive abilities, mood, behavior and neurological function. These data are uploaded by the Data Core to the National Alzheimer Coordinating Center (NAAC). Blood samples are sent to the National Cell Repository for Alzheimer Disease (NCRAD). Limited cerebrospinal fluid samples are stored in the Pathology Core. The Core recruits and follows a pool of participants who can be invited to participate in research studies, including clinical trials, observational studies [link to vascular cohort study], and the brain donation program [link to Brain Research Program]. To discuss recruit of participants for research studies, contact Dr. Schneider: email firstname.lastname@example.org.
Lon Schneider MD, Leader, Clinical Core.
Lon Schneider is internationally recognized in clinical drug development for Alzheimer disease and cognitive disorders, neuropsychiatric, and behavioral disorders, has led numerous clinical trials for AD and MCI therapeutics, consults with numerous development programs, participated in the design and operations of several early and later phase proprietary development programs for AD, directed multicenter trials in AD and major depression, including the paradigm shifting CATIE-AD trial. More recently, he examined evidence for secular changes in AD trials characteristics and outcomes, and is conducting work using trials simulations from large metadatabases to assess the effects of Alzheimer-related biomarkers and genotypes on the efficiency of targeted clinical trials in order to improve trials methods. He serves on the steering committees of the NIH ADCS, the NIH ADNI, and the Banner Alzheimer Prevention Initiative.
Freddi Segal-Gidan, PA, PhD., Co-Leader, Rancho Satellite
Freddi Segal-Gidan has extensive experience as both a clinician and researcher in the field of cognition and aging. She is the Director of the California Alzheimer Disease Center (CADC), located at Rancho Los Amigos National Rehabilitation Center in Downey, CA. In addition, as Co-Leader of the ADRC Clinical Core, Dr. Segal-Gidan directs all clinical and research operations at the Rancho site. The Rancho satellite has a particular focus on recruiting and following Spanish speaking Latinos in the ADRC research cohort.
Michael Harrington, MD. Co-Leader, HMRI satellite
Dr. Harrington directs the clinical core-affiliated satellite at Huntington Medical Research Institute (HMRI). His research is directed at understanding brain pathophysiology in order to improve therapy. His strategy employs compositional studies of blood and cerebrospinal fluid to identify molecular changes that are correlated with clinical dysfunction; then to elucidate specific underlying mechanisms. Recently, his lab found evidence of central dysregulation of lipids in asymptomatic (preclinical) Alzheimer’s disease from CSF brain-derived membranes. Notably, the changes included stage specific changes that differ between NCI, preclinical AD, MCI, and AD.
