Neuropsychological assessment of adults and geriatric patients; evaluation of age-related cognitive disorders; forensic and medico-legal cognitive, neurobehavioral evaluation
Dr. Browndyke is a faculty member of Department of Psychiatry & Behavioral Sciences, and he holds affiliate faculty appointments with the Duke Brain Imaging & Analysis Center (BIAC), Duke Institute for Brain Science (DIBS) and Center for Cognitive Neuroscience (CCN). He has dual appointment to the Duke University Medical Center and the Durham VA Medical Center, the latter of which is where his clinical work is currently conducted.
Dr. Browndyke's clinical expertise is focused upon; 1.) adult and geriatric populations with an emphasis in the assessment, diagnosis, and treatment of dementia and related disorders and 2.) forensic/medicolegal evaluation of adults and US veteran patient populations.
Dr. Browndyke's 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.
