What is the history of Hallucinogen Persistent Perception Disorder?
When was Hallucinogen Persistent Perception Disorder discovered? What is the story of this discovery? Was it coincidence or not?
It was known back in the sixties as "brain-fried" or "flashbacks" and similar names.
It has started to be known as "HPPD" since the late 90's to early 2000's.
No one has really "discovered" HPPD, it has been named that way after many reports of people having permanent visuals after taking certain drugs.

Reports of flashbacks date back decades ago, even a century. E.g. mescaline induced flash backs (Ellis, 1898).
In 1986 the publication of DSM-III-R by the American Psychiatric Association acknowledged flashbacks as a diagnosis under 'post hallucinogen perception disorder'. These disorders were reviewed and refined in the DSM-IV as 'Hallucinogen Persisting Perception Disorder".
