Summary
The term "flashback" has been used differently across psychedelic and post-traumatic stress disorder (PTSD) research over time. This historical analysis traces how the concept originated in the 1960s with psychedelic experiences, then was later adopted in PTSD literature to describe involuntary re-experiencing of traumatic events. The paper argues that the term's meaning has shifted and sometimes become conflated, leading to confusion in clinical and research contexts. It examines the historical development of the term and its current usage, highlighting the need for clearer definitions to improve diagnostic accuracy and scientific communication.
