摘要

Rationale

Since the earliest LSD research, psychedelics have been claimed to enhance autobiographical memory. Revisiting and processing autobiographical memories has further been suggested to be a major component of the therapeutic action of psychedelics. However, modern psychedelic research has largely neglected autobiographical elements of psychedelic experiences, and many vital questions remain unanswered.

Objectives

We present and discuss six open questions related to psychedelics and autobiographical memory: (1) Do psychedelics enhance autobiographical recall? (2) Is recall and processing of significant autobiographical (e.g., traumatic) memories a common part of psychedelic experiences? (3) Do psychedelics promote the development of false or inaccurate memories? (4) How do autobiographical memories change if they are recalled and reconsolidated under the effects of psychedelics? (5) What are memories of psychedelic experiences like? (6) Are autobiographical experiences under psychedelics of particular importance for their therapeutic effects?

Results

We present the background and current limited state of evidence for each question and provide suggestions on how future studies could best address them.

Conclusions

Besides advancing basic research, answering these pressing questions is highly relevant for the possible therapeutic use of psychedelics, both in terms of developing and optimizing new interventions and for avoiding iatrogenic harms. Ideally, future psychedelic-assisted interventions could harness the possible synergies between the effects of psychedelics and existing memory-based therapies.
