The Safety and Efficacy of Psychedelic-Assisted Therapies for Older Adults: Knowns and Unknowns

Psychedelics and related compounds have shown efficacy for the treat-ment of a variety of conditions that are prevalent among older adults, including mood disorders, the psychological distress associated with a serious medical illness, post-traumatic stress disorder (PTSD), and pro-longed grief disorder. Psychedelics also have properties that could help provide therapeutic benefits for patients with dementing disorders, as well as promoting personal growth among healthy older adults. This article focuses on psilocybin, a classic psychedelic, and MDMA, a substi-tuted amphetamine with properties similar to classic psychedelics. Both act on the 5HT2A receptor. Psychedelics can be safely administered to healthy adults in controlled conditions. However, both psilocybin and MDMA can increase blood pressure and heart rate, which could be a concern if used in older adults with cardiovascular disease. Very few older adults or patients with serious comorbidities have been included in clinical trials of psychedelics to date, raising the question of how generalizable study results are for the patients that most geropsychia-trists will be treating. Research on the neurophysiologic and mechanistic effects of psychedelics in older adults could also provide insights into the aging brain that could have clinical applications in the future.
