About this trial
This is a randomized, sham-controlled trial to determine whether treatment with transcranial direct current stimulation (tDCS) is superior to a sham condition at reducing the symptoms of depression in pregnant people with moderate to severe depression. The study aims to enrol 156 participants across all sites. Data collection occurs at baseline, immediately after treatment, every 4 weeks during pregnancy and 4-, 12-, 26- and 52-weeks postpartum
