McWilliams Psychiatry

Physician-Led Bipolar Disorder Treatment in Columbia, MD

Have you noticed your mood, energy, or motivation cycling in ways that feel outside your control — highs that push you too far, lows that pull you under? Dr. McWilliams offers direct, physician-led evaluation and treatment of adults living with bipolar disorder in Maryland, Virginia, and Wisconsin.

What is Bipolar Disorder?

Bipolar disorder sits at both ends of a diagnostic problem — it is frequently misdiagnosed in people who don’t have it, and just as frequently missed in people who do. Getting the diagnosis right is one of the most important things a thorough psychiatric evaluation can accomplish.

Bipolar disorder develops through a combination of genetic vulnerability, neurobiological factors, and environmental triggers. Episodes are often set off by disrupted sleep, major life stressors, or substances — which is why a thorough psychiatric evaluation frequently reveals more than the mood symptoms alone. Understanding the full picture is essential to building a treatment plan that actually holds.

Some patients come in already knowing they have bipolar disorder but have struggled to find stable, effective treatment. Others have been treated for depression for years without adequate response — unaware that the full diagnosis hadn’t been made. Many are also managing co-occurring conditions that complicate the clinical picture considerably.

Most people achieve lasting stability with the right evaluation and treatment. Dr. McWilliams specializes in exactly that kind of thorough, individualized care.

Bipolar I Disorder

Characterized by manic episodes lasting at least seven days, often requiring hospitalization, and typically accompanied by depressive episodes. The manic phase can involve elevated mood, decreased need for sleep, impulsivity, and significantly impaired judgment.

Bipolar II Disorder

Defined primarily by severe, recurrent, and often treatment-resistant depression. Patients frequently spend years cycling through antidepressants without adequate relief — not because the medications are wrong, but because the underlying diagnosis is. Hypomanic episodes may or may not be prominent, and many patients never identify them as abnormal. The depressive burden is the defining feature of this illness, and recognizing it as bipolar rather than unipolar depression changes the entire treatment approach.

Bipolar Disorder with Anxiety, ADHD, or Substance Use

Bipolar disorder rarely occurs in isolation. It commonly co-occurs with anxiety, ADHD, substance use, and insomnia. Treating only the mood component without addressing co-occurring conditions is one of the most common reasons treatment fails.
