David A. Merrill, MD, PhD, is an adult and geriatric psychiatrist with double-board certification by the American Board of Psychiatry and Dr. Merrill has worked for several decades with patients suffering the behavioral health sequelae of age-related neurodegenerative disorders such as Alzheimer's disease and Parkinson's disorder. His more recent clinical and research work have expanded to include patients with history of head trauma, tumor, and stroke. Through his early adoption of emerging clinical practice technologies, Dr. Merrill has developed a "precision holistics" approach that combines personalized genetic and biomarker data with the best evidenced-based treatments available for alleviating depression and cognitive dysfunction within the context of aging.
