Clinical Interests:
Neuropsychological assessment of adults and geriatric patients; evaluation of dementia-related disorders and mild cognitive impairment

Research Interests:
Dr. Browndyke is a faculty member of the Joseph and Kathleen Bryan Alzheimer’s Disease Research Center.  In addition to his primary appointment in the Department of Psychiatry & Behavioral Sciences, he holds affiliate faculty appointments with the Duke Brain Imaging & Analysis Center (BIAC) and Center for Cognitive Neuroscience (CCN).  

Dr. Browndyke's clinical expertise is focused upon adult and geriatric populations with an emphasis in the assessment,  diagnosis, and treatment of dementia and related disorders, while his research interests include:

1) The use and development of functional and structural neuroimaging biomarkers for dementia diagnosis, monitoring of disease progression, and treatment outcome.

2) Cognitive performance patterns associated with possible pathological cognitive change in the elderly [e.g., mild cognitive impairment (MCI),cognitive impairment – no dementia (CIND), vascular cognitive impairment - no dementia (V-CIND), etc.].

3) The impact of peri-operative and chronic ischemic cerebrovascular damage on cognitive functioning and dementia risk.
