Psychedelic-assisted therapy produces sustained reductions in death anxiety and state and trait anxiety among people facing life-threatening illness. A meta-analysis of five randomized controlled trials found that serotonergic psychedelic therapy, which acts more rapidly than antidepressants, decreased both the fear of death and the transient and chronic anxiety that accompany serious disease. The analysis used the State Trait Anxiety Inventory to measure anxiety in the context of life-threatening illness. These results highlight psychedelic therapy as a promising alternative to limited existing treatments such as psychotherapy and antidepressant drugs. Future research should test whether these benefits extend to illness anxiety disorder and somatic symptom disorders.
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.
