Psilocybin Treatment as an Adjunct to Cognitive Behavioral Therapy for Eating Disorders: Therapeutic Rationale & Considerations for Protocol Development.

Behavioral Sciences March 6, 2026 Elena Koning, Susan Gamberg, Aaron Keshen 1 citation

Eating disorders (EDs) remain challenging to treat, with high dropout and low remission rates in cognitive-behavioral therapy for EDs (CBT-ED). Psilocybin treatment (PT) demonstrates therapeutic potential to enhance CBT-ED by exerting several neurobiological, psychological, and experiential effects (e.g., antidepressant, neuroplasticity, emotional openness) that are hypothesized to increase...

Why psychedelic-assisted therapy studies in eating disorders risk missing the mark on outcomes: a phenomenological psychopathology perspective.

Journal of Eating Disorders September 2, 2025 Elena Koning, Riccardo Miceli Mcmillan, Aaron Keshen et al. 3 citations

Psychedelic-assisted therapy (PAT) is an emerging intervention in psychiatry, for which there is preliminary evidence for effectiveness in eating disorders (EDs). The subjective psychedelic experience is considered an important driver of positive outcomes following PAT; however, conventional study design approaches often overlook many of the nuances inherent to the experience. Consequently,...
