DMT was detected in the urine of 47% of those diagnosed by their psychiatrists as schizophrenic, 38% of those with other non-affective psychoses, 13% of those with affective psychoses, 19% of those with neurotic and personality disorders and 5% of normal subjects. Ninety-nine patients were interviewed in a semi-standardized fashion, and also categorized according to a variety of operational definitions of the psychoses. The operational definitions failed to reveal any group significantly more correlated with urinary DMT than a hospital diagnosis of schizophrenia, but a discriminant function analysis of symptomatology could be used to define a group of 21 patients of whom 15 (71%) excreted detectable DMT. There was a general relationship between psychotic symptoms and urinary DMT, but specifically schizophrenic symptoms did not appear to be major determinants of DMT excretion.<\/jats:p>","DOI":"10.1017\/s0033291700018304","type":"journal-article","created":{"date-parts":[[2009,7,9]],"date-time":"2009-07-09T16:07:37Z","timestamp":1247155657000},"page":"649-657","source":"Crossref","is-referenced-by-count":26,"title":["Urinary dimethyltryptamine and psychiatric symptomatology and classification"],"prefix":"10.1017","volume":"6","author":[{"given":"R.","family":"Rodnight","sequence":"first","affiliation":[]},{"given":"R.
