Researchers developed an AI algorithm to analyze brain scans and clinical data, predicting treatment response with 8-week accuracy.
A large long-term study found that women's antidepressant use increases after later life divorce or break-up, with a significant increase in the 4 years leading up to the event. Women's use tends to tail off only slightly and briefly after re-partnering, while men's use returns to pre-break-up levels within a year.
A preliminary study found that most stroke survivors can safely take two common types of antidepressants without increasing the risk of hemorrhagic stroke. However, patients on dual anti-platelet therapy may be at increased risk of bleeding.
A study of 215 veterans found that nearly half experienced significant depression score drops, while about one quarter saw a halving of their scores. About 15% achieved full remission after six weeks of ketamine infusions, suggesting the treatment can provide substantial relief for those with complex mental health needs.
