I saw an outstanding article in the February 2012 issue of Current Psychiatry about treating depression during pregnancy. I think it’s important to point out that for women who experience depression during pregnancy, psychiatrists don’t always think the only appropriate treatment are antidepressants. In fact, for mild depressive symptoms without functional role impairment, suicide ideation, or psychosis, psychotherapy is the treatment of choice. Interpersonal therapy (IPT) or cognitive-behavioral therapy are safe and effective treatments during pregnancy .
Complementary treatments can also be effective and can prevent relapse when antidepressants and mood stabilizers have to be discontinued. Mind-body approaches can help, including mindfulness-based stress reduction, yoga, and progressive relaxation. Mindfulness yoga can decrease depressive symptoms and promote maternal-fetal attachment. It is wise and safe to treat severe mood disorders, especially those marked by psychosis or catatonia, with medications and electroconvulsive therapy (ECT).
