Abstract

The study reports a follow-up assessment of 48 patients with concomitant drug abuse at the first admission for psychosis. We focused on the diagnostic distinction between primary psychosis with concomitant drug abuse and drug induced psychosis, to observe whether the diagnoses are stable over time and whether the clinical course significantly differs. The study examined 25 primary psychotic disorder with comorbid drug abuse and 23 drug-induced psychotic disorder patients. Diagnostic and psychopathological assessments were made at baseline and at follow-up. Mean follow-up period was 4.96 years. Patients with comorbid Drug Abuse exhibited higher scores in the item Unusual Content of Thought at baseline than drug-induced psychotic disorder patients: 5.48 vs 4.39 while the two patients groups did not differ in any of the BPRS items evaluated at follow-up. The primary psychosis with comorbid drug abuse and the substance induced psychosis groups were similar regarding diagnostic stability, and a diagnosis of schizophrenia at follow-up occurred similarly. There was no evidence that Drug Induced psychotic patients’ symptoms tend to improve more after cessation of drug abuse. An earlier age of onset was found in primary psychotic patients, particularly for patients diagnosed as affected by schizophrenia at follow up. These results might reflect the uncertainty of the distinction between Primary and Drug Induced Psychosis and the difficulties in applying the DSM IV-TR criteria for diagnosing comorbid drug use disorders and psychotic disorders.
