About Daniel D Sewell, MD

Daniel D. Sewell, MD, is a board-certified psychiatrist who treats older adults with behavioral health issues.

As a geriatric psychiatrist, he assesses and treats seniors with depression and anxiety, and other conditions, including severe behavioral disturbances from dementia. He also helps people manage their medications and provides psychotherapy for adults of all ages.

Dr. Sewell is co-director of UC San Diego Health's Memory, Aging and Resilience Clinic (MARC), which offers assessments and consults for people with suspected memory issues or cognitive decline.

He is also a professor of psychiatry, associate vice chair for geriatric psychiatry, and co-director of geriatric psychiatry at UC San Diego School of Medicine.

His research has explored the utility of a widely used neuropsychological test to distinguish between depression and early dementia in older adults. More recently, Dr. Sewell's research has examined sexual health in older adults, optimal prescribing of medications for people with dementia, medical illnesses that mimic psychiatric illnesses, and the mental health of older individuals in the LGBTQ community.

Dr. Sewell completed fellowship training in geriatric psychiatry and residency training in psychiatry at UC San Diego School of Medicine. He also completed residency training in psychiatry at University of New Mexico School of Medicine. He earned his medical degree at University of Iowa Carver College of Medicine in Iowa City.
