Atypical course in severe catatonic schizophrenia in a cannabis-dependent male adolescent: a case report

摘要

IntroductionAdolescents with psychoses usually have full recovery from their first psychotic episode, but the first relapse often arises within 2 years of the first episode. Cannabis-related psychoses are difficult to distinguish from schizophrenic psychoses. Here, we describe a particularly severe clinical case, with a first psychotic episode occurring after heavy cannabis smoking, an atypically long symptom-free duration, and a subsequent non-substance-related episode.
