Link to PHHP Research Profile
Dr. Vonetta Dotson is an Associate Professor of Clinical and Health Psychology in the College of Public Health and Health Professions and an affiliate faculty of the Department of Neuroscience in the College of Medicine. She received her Ph.D. from the University of Florida in 2006 with a specialization in neuropsychology and a certificate in gerontology. She completed her postdoctoral training in the Laboratory of Personality and Cognition in the National Institute on Aging Intramural Research Program under the mentorship of Drs. Susan Resnick and Alan Zonderman.
Dr. Dotson’s clinical focus is primarily in the neuropsychological assessment of elderly patients with a variety of neurocognitive disturbances including dementia, mild cognitive impairment, movement disorders, neurocognitive sequelae of medical disorders (e.g., stroke, tumors), and neuropsychiatric disorders.
Dr. Dotson’s research program focuses on studying the underlying neurobiology of late-life depression and its relationship to cognitive changes and functional deficits in the elderly. Currently, work in her lab is aimed at 1) using cognitive and neuroimaging methods to examine the depressive spectrum hypothesis—whether depression is best conceptualized as a continuum, starting with subthreshold depressive symptoms and dysthymia and ending with major depression, 2) investigating whether particular symptom dimensions of depression (e.g., somatic vs. affective symptoms) have distinct cognitive and neural correlates, and 3) examining whether aerobic exercise improves memory functioning and alters memory-related brain functioning in depressed older adults.
