A meta-analysis of five clinical trials found that psilocybin is superior to placebo for reducing end-of-life anxiety symptoms. Psilocybin reduced state anxiety at 1 day and 2 weeks after treatment, and trait anxiety at 1 day, 2 weeks, and 6 months after treatment. Psilocybin caused a temporary increase in systolic and diastolic blood pressure compared with placebo. There were no significant differences between psilocybin and placebo in rates of stopping treatment, serious adverse events, or heart rate. The authors conclude that psilocybin-assisted therapy can improve end-of-life anxiety without serious side effects, but note the small sample sizes and high heterogeneity in long-term outcomes.

A meta-analysis of ten studies found that one or two doses of psilocybin produce rapid and sustained antidepressant effects lasting up to six months. Depressive symptoms decreased substantially, with the largest effect at one week (standardized mean difference -1.74) and a still-large effect at six months (-1.12). Higher doses and two sessions were linked to greater improvement. Psilocybin raised systolic blood pressure by 19.00 mmHg and diastolic by 8.66 mmHg, but discontinuation rates and heart rate changes were similar to placebo. The findings suggest psilocybin has favorable cardiovascular safety and acceptability for treating depression.

More than half of people with major depressive disorder do not respond to standard treatments, prompting interest in alternatives such as exercise and psychedelics. This commentary examines how these two approaches might work together. Biologically, psychedelics briefly boost brain-derived neurotrophic factor (BDNF) signaling, while exercise provides sustained BDNF elevation; psychedelics enhance neuroplasticity mainly in the cortex, whereas exercise promotes hippocampal neurogenesis; both increase serotonin release. Psychologically, psychedelics may help people adopt exercise habits, and exercise may improve emotional resilience, potentially deepening the psychedelic experience. The authors suggest that these complementary mechanisms warrant future research on their combined efficacy, tolerability, safety, and neurobiology.
