Half of patients with post-traumatic stress disorder (PTSD) do not respond to traditional therapies. A review of six phase II randomized controlled trials indicates that MDMA-assisted psychotherapy can reduce PTSD symptoms even in treatment-resistant cases. MDMA appears to work by increasing neurohormones such as dopamine, serotonin, norepinephrine, and oxytocin, and by modulating brain regions involved in fear and anxiety. The FDA has granted MDMA-assisted psychotherapy a "breakthrough therapy" designation. Further research is needed to determine whether the benefits outweigh the risks and how it might fit into existing PTSD treatment options.

Suicidal behavior is common among people with bipolar disorder and is the leading cause of death in this group, with rates remaining high despite standard treatments like lithium, antidepressants, and psychotherapy. A review of PubMed identified few studies on acute suicidality and lithium or clozapine, but 14 studies on ketamine, esketamine, or glutamate-related treatments. Glutamatergic abnormalities are present in both bipolar disorder and suicide. The NMDA antagonist ketamine and its S-enantiomer esketamine appear to decrease acute suicidality, possibly by rapidly remodeling glutamate activity. Intranasal esketamine or subcutaneous ketamine, and possibly other glutamate receptor modulators, may improve suicidal behavior in unipolar and bipolar depression, suggesting glutamatergic modulators could reduce acute suicidality and mortality in bipolar disorder.
