Bipolar Depression

BIPOLAR DEPRESSION

Depression occurring within bipolar disorder requires particular diagnostic and treatment consideration.

A person with bipolar disorder has experienced, or has the biological vulnerability to experience, episodes of mania or hypomania in addition to depression. That broader pattern can significantly change how depression should be treated.

Why bipolar depression can be missed: people often seek treatment during depression, while hypomanic periods may not initially feel like illness. Careful history should consider sleep, energy, activation, impulsivity, irritability, family history, and previous medication responses.

When treatment repeatedly fails, diagnostic certainty should not automatically increase. Sometimes it should decrease.

Treatment may include medications with established roles in bipolar disorder, psychotherapy, attention to sleep and circadian stability, and selected interventional treatments. TMS has been studied in bipolar depression and may be considered for selected patients, although the evidence base is smaller than for major depressive disorder.

Ketamine has also been studied in bipolar depression and may produce rapid antidepressant improvement in some patients, but evidence is less extensive than for unipolar TRD. IV ketamine is off-label for bipolar depression.

Spravato does not have a specific FDA-approved indication for bipolar depression.

In bipolar disorder, getting better and remaining stable have to be considered together.
