Bipolar Disorder in Pregnant women: Prevalence, Risk & Key Differences

Key things to know What the evidence shows
How common is it? 0.7% pooled when limited to diagnostic-interview perinatal studies†
Is it more common among pregnant women? Not clearly higher prevalence, but course/relapse risk changes substantially
Are pregnant women at higher risk? Yes for mood episodes among women with established BD
How much higher is the risk? In women with established BD, ~51.4% had a bipolar-spectrum episode during pregnancy in one study
How often can it be missed? Very high if bipolar depression is mistaken for unipolar/perinatal depression
Does it show up differently among pregnant women? Yes contextually
How might it look different? Sleep changes, medication decisions and pregnancy-related emotional changes complicate recognition
What commonly occurs alongside it? Anxiety; depression; substance use
What can it be confused with? Unipolar depression; normal pregnancy-related changes; thyroid disease; medication/substance effects
Common screening tool MDQ can be used cautiously
Separate screening tool for pregnant women No universally accepted pregnancy-specific BD screener
