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.
