Leveraging meditation research for the study of psychedelic-related adverse effects.

International Review of Psychiatry December 1, 2024 Roman Palitsky, Nicholas K. Canby, Nicholas T. van Dam et al. 6 citations

Psychedelics have shown early evidence for a range of benefits and low harm profiles in extant research. However, adverse effects (AEs) research in psychedelics has been limited, leading to underspecified AE profiles, inconsistent measurement, and potential undercounting of AEs. The development of safe, effective psychedelic therapies and treatments for AEs when they occur requires a thorough...

Rapid Effects of MDMA Administration on Self-Reported Personality Traits and Affect State: A Randomized, Placebo-Controlled Trial in Healthy Adults.

Journal of Psychoactive Drugs October 23, 2024 Jessica L Maples-Keller, Courtland S Hyatt, Nathaniel L Phillips et al. 2 citations

3,4-methylenedioxymethamphetamine (MDMA) assisted therapy has been shown to be a safe and effective treatment for PTSD and emerging research suggests a change in personality traits may be a factor in treatment response. Most prior research on MDMA and personality has focused on cross-sectional comparisons of MDMA users and non-users; as such, well-controlled research assessing personality and...

A framework for assessment of adverse events occurring in psychedelic-assisted therapies

Journal of Psychopharmacology July 31, 2024 Roman Palitsky, Deanna M Kaplan, John Perna et al. 32 citations

Objective: Despite considerable research examining the efficacy of psychedelic-assisted therapies (PATs) for treating psychiatric disorders, assessment of adverse events (AEs) in PAT research has lagged. Current AE reporting standards in PAT trials are poorly calibrated to features of PAT that distinguish it from other treatments, leaving many potential AEs unassessed. Methods: A...
