[Psychedelic experiences at the onset of productive episodes of endogenous psychoses]

[Article in German]


Hallucinogenic drugs (psychedelics, e.g. Psilocybin, Mescaline, LSD) induce in humans qualitatively altered states of consciousness (ASC), which can be used as experimental models for endogenous psychosis. However, some researchers claim that these ASCs are not appropriate models for schizophrenia. We report two clinical cases of acute endogenous psychoses demonstrating striking similarities to psychedelic experiences. We consider the psychedelic-induced ASC to be an appropriate model for the beginning acute endogenous psychotic episode, but not for the schizophrenic disease as a nosological entity.
