Abstract:
Novel interventions for post-traumatic stress disorder (PTSD) leverage the psychoactive properties of psychedelic compounds, such as ketamine, 3,4-methylenedioxymethamphetamine and psilocybin, which may overcome limitations of conventional treatments. Through the modulation of pathways involved in synaptic plasticity, psychedelic interventions are believed to enhance the mechanisms underlying memory processing and extinction. Multi-modal approaches to patient care can use existing treatments in combination with psychedelics to improve the efficacy of current psychotherapies, producing rapid and lasting improvement to chronic physiological and psychological symptoms. Modern methods for predicting treatment response will allow clinicians to personalise psychedelic interventions to the individual, capitalising on quantitative evidence to provide precision medical care. This review serves to identify limitations of the current treatment paradigm for PTSD, highlight how emerging psychedelic interventions may offer a solution to these considerations and explore the promise of precision medicine approaches for the future of PTSD treatment.
