Differences between substance-induced psychotic disorders and non-substance-induced psychotic disorders and diagnostic stability.

Several hypotheses have been proposed to explain the comorbidity between psychotic disorders and substance use, one of them being the capacity of some to induce psychotic symptoms, although the transition from psychotic episodes induced by substances to schizophrenia has been less studied. In this study, differential variables between patients with induced and non-induced psychosis are determined, and the evolution and change of diagnosis of those induced to schizophrenia in the follow-up is analyzed. This is an observational case-control study with 238 patients admitted to the acute care unit for psychotic episodes between December 2003 and September 2011.

Correction to: Once‑Monthly Long‑Acting Injectable Aripiprazole for the Treatment of Patients with Schizophrenia and Co‑occurring Substance Use Disorders: A Multicentre, Observational Study.

A randomized, 1-year follow-up study comparing LAI aripiprazole with LAI paliperidone in patients with psychosis, mostly schizophrenia, and SUD reported a large effect of the change from baseline in the CGI severity score, from 5.9 to 2.4 for LAI aripiprazole and from 5.

Once-Monthly Long-Acting Injectable Aripiprazole for the Treatment of Patients with Schizophrenia and Co-occurring Substance Use Disorders: A Multicentre, Observational Study.

Aim: To evaluate the efficacy and impact of long-acting injectable (LAI) aripiprazole in patients with schizophrenia with a coexisting substance use disorder (SUD).

Patients And Methods: A multicenter, observational, descriptive and retrospective study was conducted in patients with a DSM-5 diagnosis of schizophrenia who had a coexisting SUD and were treated with LAI-aripiprazole. Disease severity was evaluated with the Clinical Global Impression (CGI) severity scale for schizophrenia, daily functioning and disability were evaluated with the World Health Organisation Disability Assessment Scale (WHODAS-2.
