“…Previous research comparing first episode psychosis samples with SIPD and PPDS has reported more frequent substance use in the SIPD group (Caton et al, 2005;Fraser et al, 2012), but further research among MA users is needed. Those with a current PPD were more likely to have accessed psychiatric treatment (including antipsychotic medication) in the past month than those with a current SIPD.…”

“…This was different from the data obtained by Fraser and colleagues, who compared the clinical, substance use, and functional characteristics of substance using FEP patients diagnosed with a substance induced psychosis (SIP) and primary psychotic disorder (PPD). No statistical difference was found between both groups in the positive and negative symptoms on investigating them by PANSS [31].…”

BackgroundThe question whether substance-induced psychotic disorders can be differentiated from schizophrenia on the basis of clinical and psychological tests performance remains inconclusive. We hypothesize that cannabis-induced psychosis and schizophrenia have different cognitive, premorbid, and clinical features. ObjectiveThe main objective of this study was to investigate and describe clinical profile of cannabis-induced psychosis and to plot a comparative study between patients with cannabis-induced psychosis and schizophrenic with regard to cognitive abilities, different personality traits as well as phenomenological differences between both groups. Patients and methods This was a cross-sectional comparative study in which 60 patients were recruited; 30 patients with diagnosed cannabis-induced psychosis and 30 patients with diagnosed schizophrenia. The patients were selected from inpatient units and outpatient psychiatric clinics at the Institute of Psychiatry, Ain Shams University, over a period of 6 months. The recruited samples were assessed by a semistructured interview on the basis of the interview (questionnaire) sheet of the Institute of Psychiatry, Ain Shams University Hospital, and the diagnosis was made on the basis of ICD-10 symptom checklist. They were also assessed by the following scales: Wechsler Intelligence Scale, Minnesota Multiphasic Personality Inventory, and Positive and Negative Symptoms Scale. ResultsWe found that cannabis-induced psychosis patients have statistically significant better cognitive functioning in the object assembly, less lie and correction, more psychopathic deviation, more antisocial and borderline traits, and less negative and general psychopathology symptoms compared with schizophrenic patients. ConclusionResults from the present study support previous evidence that tasks of cognitive functions, personality assessment, and clinical evaluation distinguish cannabisinduced psychosis and schizophrenia even in the earliest stages of illness and that the two disorders can be differentiated on the basis of areas of selective deficit. However, the present results also support the hypothesis of a continuum of illness severity, in which significant deficits are evident in all diagnostic groups, but with different severity.

“…Increasingly literature is suggesting that there are discernable differences in substanceinduced versus primary psychotic disorders 73 and one of these differences is involvement in the criminal justice system. 74…”

Objective.Evidence is clear that the nation is experiencing an increasing number of incompetent to stand trial (IST) admissions to state hospitals. As a result, defendants in need of treatment can wait in jail for weeks for admission for restoration. This study was conducted to better understand this growing population and to inform hospital administration about the characteristics of IST admissions.Methods.The study was conducted at the Department of State Hospitals (DSH) facility in Napa (DSH-Napa), a 1200-bed primarily forensic inpatient psychiatric facility located in northern California. The records of patients found IST and admitted to DSH-Napa for restoration of competence between the dates of 1/1/2009 and 12/31/2016 were eligible for inclusion in the study.Results.There were a total of 3158 unduplicated IST admissions available during the specified time period. Our data indicate that the number of admissions with more than 15 prior arrests increased significantly, from 17.7% in 2009 to 46.4% in 2016. In contrast, the percent of patients reporting prior inpatient psychiatric hospitalization evidenced a consistent decrease over time from over 76% in 2009 to less than 50% in 2016.Conclusion.Our data add to the body of literature on the potential causes of the nationwide increase in competency referrals. The literature is clear that jails and prisons are now the primary provider of the nation’s mental health care. Our data suggest that another system has assumed this role: state hospitals and other providers charged with restoring individuals to competence.

Differentiating first episode substance induced and primary psychotic disorders with concurrent substance use in young people

Abstract: This clinical profile of SIPD could help to facilitate the accurate diagnosis and treatment of SIPD versus PPD in young people with first episode psychosis admitted to an inpatient psychiatric service.
