A small proportion of people with treatment-resistant depression experience clinically significant worsening of symptoms during a course of intravenous ketamine, but the rate is very low—between 1.83% and 5.49% across infusion time points—and similar to that seen with conventional antidepressants. In a retrospective analysis of 164 adults (142 with unipolar depression and 22 with bipolar depression) who received four ketamine infusions over two weeks, no individuals with bipolar depression reported worsening. The findings suggest that symptomatic worsening with ketamine is uncommon, though the study's uncontrolled, single-center design limits certainty.

A systematic review of treatments for suicidality among psychiatric inpatients aged 18–65 found that intravenous ketamine produced the most consistent rapid reduction in suicidality among 14 pharmacologic trials. Among 35 nonpharmacologic trials—including chronotherapy, neurostimulation, and psychotherapies—results were mixed, with some interventions showing potential benefit, especially for mood, personality, and trauma-related disorders. Many studies had methodological limitations such as nonrandomized designs and lack of control groups. The review calls for larger, well-designed trials to confirm effectiveness.

A 10-week trial of Mindfulness-Based Boxing Therapy (MBBT) for adults with major depressive disorder or generalized anxiety disorder showed high retention (89%), attendance (84%), and satisfaction (98%). Among eight outpatients in Toronto, depression scores dropped 54%, anxiety 51%, and distress 36%, while mindfulness increased 79%. Participants reported benefits including cathartic release, improved self-esteem, and a sense of community. The authors conclude that MBBT is feasible and acceptable as an exercise-based intervention, but caution that larger randomized trials are needed to confirm clinical benefits.
