From Depression to Mania: The Dual Effects of Antidepressant-Induced Hippocampal Neurogenesis

This research explores the dual function of antidepressant-induced hippocampus neurogenesis in the treatment of depression, emphasising both the positive effects and possible drawbacks. Antidepressants, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), have been demonstrated to stimulate the growth of new neurones in the brain, resulting in positive alterations to the structure and function of the hippocampus. These modifications contribute to enhanced mood and cognitive abilities. Nevertheless, this heightened neurogenesis can also induce a state of moderate mania in individuals who have a genetic inclination towards bipolar disease. The research highlights the significance of personalised medicine techniques in treating depression and emphasises the need for closely monitoring mood changes in patients, based on a thorough examination of clinical studies and case reports. Future research should focus on clarifying the biological processes involved and improving therapeutic options for treating depression while reducing the risk of negative mood changes.
