Recent research suggests that all three statements are correct. Studies have found that high stress hormones, such as cortisol, can suppress neurogenesis in the hippocampus, which may contribute to the development of depression (A). Additionally, low hippocampal volume has been identified as a potential risk factor for depression and may be a biomarker for the disorder (B). Finally, electroconvulsive therapy (ECT) has been found to promote neurogenesis in the hippocampus, which may be one mechanism by which ECT exerts its therapeutic effects in treating depression (C).
