J Clin Psychiatry 1997;58(2):85 [letter]

Letter to the Editor

Sir: Hallucinogen persisting perception disorder is the reexperiencing of the perceptual symptoms experienced while intoxicated with the hallucinogen. Examples of these perceptual distortions include geometric hallucinations, false perceptions of movement in the peripheral visual fields, flashes of color, positive afterimages, macropsia, and micropsia. Various pharmacologic treatments of “flashbacks,” including neuroleptics and benzodiazepines, and electroconvulsive therapy have met with limited success.
