# Bipolar Depression

It looks like depression — but its treatment is very different. Bipolar depression is easily overlooked.

Bipolar disorder is a brain disorder with a strong genetic and neurobiological basis; it is not a matter of “willpower.” Twin and family studies generally report heritability estimates of approximately 60–80% (Mullins et al., Nat Genet 2021).

The problem is this: People with bipolar disorder spend approximately 75% of their symptomatic time in the depressive phase, which closely resembles major (unipolar) depression. As a result, an accurate diagnosis may be delayed by an average of ~9 years after the first depressive episode (Nierenberg et al., JAMA 2023).

Why does this delay matter? Because in active bipolar depression, “conventional” treatments may be inadequate — or even harmful at times. In a registry study, antidepressant monotherapy without a mood stabilizer increased the risk of mania by ~2.8-fold (Viktorin et al., 2014). Similarly, methylphenidate (a conventional ADHD medication) monotherapy increased the risk of mania in patients not taking a mood stabilizer (Viktorin et al., 2016). In both cases, this risk was not observed when the medication was given alongside a mood stabilizer.

An important caveat: The risk of an antidepressant-induced “switch” remains debated in the literature; nevertheless, guidelines (ISBD, CANMAT) do not recommend monotherapy.

Effective treatments are available: Quetiapine, lurasidone, cariprazine, olanzapine–fluoxetine, and lamotrigine have been found superior to placebo in acute bipolar depression (Yıldız et al., Lancet Psychiatry 2023). Lithium has the strongest evidence for long-term relapse prevention.

The key principle: Medication is the foundation of treatment; psychotherapy is a valuable ADJUNCT — not a stand-alone treatment. When risk is high (suicidality, psychotic/mixed features), bipolar-specific treatment must be prioritized.
