Physician-Led Depression Treatment in Columbia, MD

Do you feel sad most days? Have you noticed that activities that used to be fun now don't hit the same? Dr. McWilliams offers direct, physician-led evaluation and treatment of adults living with depression in Maryland, Virginia, and Wisconsin.

What is Depression?

Depression is one of the most common — and most treatable — medical conditions in psychiatry. It is also one of the most frequently undertreated.

Major Depressive Disorder (MDD) affects how you feel, think, and function in daily life. It is a neurobiological condition involving changes in brain chemistry, structure, and circuitry — including serotonin, dopamine, norepinephrine, and the stress response system. It is not a character flaw sign of weakness. 

Depression varies from person-to-person. Some patients experience profound sadness; others feel numb, irritable, or simply unable to engage with life the way they used to. Even high-performing professionals may remain functional on the outside while struggling underneath the surface.

With the right evaluation and treatment — one that accounts for your full biological, psychological, and social history — most people experience meaningful, lasting improvement. Dr. McWilliams specializes in exactly that kind of thorough, individualized care.

Major Depressive Disorder (MDD)

Characterized by persistent depressed mood or loss of interest for at least two weeks, with significant impairment in functioning.

Treatment-Resistant Depression

When two or more antidepressants have not produced adequate relief. Dr. McWilliams has specific expertise in this area, including augmentation strategies and emerging options.

Persistent Depressive Disorder (Dysthymia)

A chronic, lower-grade form of depression lasting at least two years. Often described as a persistent low ceiling on mood and energy.
