Rachid H, Saif Z, Raoui S, Serhier Z, Agoub M. Does cannabis affect cognitive functioning in patients with schizophrenia? Schizophr Res Cogn 2024; 36:100299. [PMID: 38196922 PMCID: PMC10772380 DOI: 10.1016/j.scog.2023.100299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 11/27/2023] [Accepted: 12/09/2023] [Indexed: 01/11/2024]
Abstract
Introduction Cannabis use impairs cognitive performance in healthy subjects; several studies have shown improved cognitive outcomes in schizophrenic patients using cannabis. The aim of this study was to evaluate the effects of cannabis use on cognitive function in Moroccan patients with schizophrenia who were cannabis users. Method Two groups were recruited in a Moroccan University Psychiatric Centre. Fifty patients diagnosed with schizophrenia according to the DSM-V who were cannabis users (SZ CANN +) and forty-nine patients diagnosed with schizophrenia according to DSM-V who do not use cannabis (SZ CANN-). Cognitive functioning was assessed using the CogState neuropsychological battery. Results The results of the study suggest that SZ CANN- patients performed better in the test of psychomotor function, attention and verbal memory. While SZ CANN+ patients performed better in the test of working memory, visual memory and emotional recognition. We found no relationship between SZ CANN+ patients and SZ CANN- patients concerning executive function. Conclusions Our results suggest that cannabis use may have different effects on neurocognitive functioning. It is associated with disorders of psychomotor function, attention and verbal memory. So, it is associated with an improvement in working memory, visual memory and emotion recognition.

Dorney K, Murphy M. Recommendations for the medical work-up of first episode psychosis, including specific relevance to Indigenous Australians: A narrative review. Early Interv Psychiatry 2021; 15:423-438. [PMID: 32543124 DOI: 10.1111/eip.12980] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2019] [Revised: 03/24/2020] [Accepted: 04/28/2020] [Indexed: 12/15/2022]
Abstract
AIMS To collate existing literature for busy practicing psychiatrists about the medical work-up for first-episode psychosis (FEP). Therefore, (a) to review current guidelines for the medical work-up of first episode psychosis. (b) To examine whether any specific recommendations for Indigenous Australians exist. (c) To produce an easy reference table of evidence based investigations. METHOD A multi-part narrative review process was undertaken. Step 1 "Source identification and summary": identified key existing national and international guidelines and expert opinions related to the medical work-up of FEP and summarised these suggestions. Step 2 "Exploration of each investigation": examined each of the identified investigations for its importance. Step 3 "Relevance to Indigenous Australians": reviewed any particular relevance to the Indigenous Australian population. Step 4 "Clinician guide": involved presenting recommended investigations in a simple table. RESULTS Multiple guidelines were identified. There was clear consensus for many aspects. However, there were also differences in the approach for some investigations. Clinical reasoning for the proposed investigations was commonly absent. There were limited specific recommendations for Indigenous Australians. Evidence and importance was explored for each investigation and auseful table for the practicing psychiatrist was constructed. Investigations were stratified into those considered to be "universal," "low yield," or "unecessary." CONCLUSION A narrative review of multiple guidelines relating to the medical work-up of FEP identified many similarities and some differences to their approach. Little additional information exists for the Indigenous Australian context. A clinician friendly worksheet for everyday use may be helpful to busy clinicians.

Abstract
Substanzinduzierte psychotische Störungen (SIPS) sind häufig und für ca. 25 % der ersten Einweisungen in eine psychiatrische Klinik verantwortlich. Aus klinischer Sicht ist aufgrund ähnlicher psychopathologischer Phänomene die diagnostische Unterscheidung zwischen SIPS und primären (genuinen oder kryptogenen) psychotischen Störungen oft eine Herausforderung. Dieser Umstand wird dadurch erschwert, dass SIPS im Zusammenhang mit Cannabis, Halluzinogenen und Amphetaminen ein erhebliches Risiko des Übergangs in eine primäre psychotische Störung (z. B. Schizophrenie) haben. Im ersten Abschnitt dieser Arbeit werden zunächst zwei exemplarische Fallvignetten aus der allgemeinpsychiatrischen und forensischen Praxis vorgestellt. Danach wird im Sinne einer selektiven Literaturübersicht die Relevanz der differenzialdiagnostischen Unterscheidung beider Störungsbilder aus der Sicht der allgemeinen und forensischen Psychiatrie in Bezug auf Therapie, Prognose und richterliche Entscheidung bezüglich der Unterbringung im Maßregelvollzug (§ 63 vs. § 64 StGB) beleuchtet. Der letzte Abschnitt hat das Ziel, ein strukturiertes Vorgehen zur differenzialdiagnostischen Unterscheidung zwischen SIPS und primären psychotischen Störungen zu erarbeiten. Die in dieser Arbeit dargestellten und diskutierten Konzepte und Befunde sollen klinisch tätigen Psychiatern und Psychologen die Diagnosestellung im allgemeinen und forensischen Kontext erleichtern.

Cannabinoid receptor CNR1 expression and DNA methylation in human prefrontal cortex, hippocampus and caudate in brain development and schizophrenia. Transl Psychiatry 2020; 10:158. [PMID: 32433545 PMCID: PMC7237456 DOI: 10.1038/s41398-020-0832-8] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 04/24/2020] [Accepted: 04/30/2020] [Indexed: 12/22/2022] Open
Abstract
Beyond being one the most widely used psychoactive drugs in the world, cannabis has been identified as an environmental risk factor for psychosis. Though the relationship between cannabis use and psychiatric disorders remains controversial, consistent association between early adolescent cannabis use and the subsequent risk of psychosis suggested adolescence may be a particularly vulnerable period. Previous findings on gene by environment interactions indicated that cannabis use may only increase the risk for psychosis in the subjects who have a specific genetic vulnerability. The type 1 cannabinoid receptor (CB1), encoded by the CNR1 gene, is a key component of the endocannabinoid system. As the primary endocannabinoid receptor in the brain, CB1 is the main molecular target of the endocannabinoid ligand, as well as tetrahydrocannabinol (THC), the principal psychoactive ingredient of cannabis. In this study, we have examined mRNA expression and DNA methylation of CNR1 in human prefrontal cortex (PFC), hippocampus, and caudate samples. The expression of CNR1 is higher in fetal PFC and hippocampus, then drops down dramatically after birth. The lifespan trajectory of CNR1 expression in the DLPFC differentially correlated with age by allelic variation at rs4680, a functional polymorphism in the COMT gene. Compared with COMT methionine158 carriers, Caucasian carriers of the COMT valine158 allele have a stronger negative correlation between the expression of CNR1 in DLPFC and age. In contrast, the methylation level of cg02498983, which is negatively correlated with the expression of CNR1 in PFC, showed the strongest positive correlation with age in PFC of Caucasian carriers of COMT valine158. Additionally, we have observed decreased mRNA expression of CNR1 in the DLPFC of patients with schizophrenia. Further analysis revealed a positive eQTL SNP, rs806368, which predicted the expression of a novel transcript of CNR1 in human DLPFC, hippocampus and caudate. This SNP has been associated with addiction and other psychiatric disorders. THC or ethanol are each significantly associated with dysregulated expression of CNR1 in the PFC of patients with affective disorder, and the expression of CNR1 is significantly upregulated in the PFC of schizophrenia patients who completed suicide. Our results support previous studies that have implicated the endocannabinoid system in the pathology of schizophrenia and provided additional insight into the mechanism of increasing risk for schizophrenia in the adolescent cannabis users.

Abstract
ObjectivesAn Early Intervention in Psychosis (EIP) programme aims to engage patients in early assessment and phase-specific interventions which are the key elements of the Irish National Clinical Programme for psychosis. This study aims to describe and review the EIP programme offered by Cork’s North Lee Mental Health Services over a 5-year period.MethodsA retrospective descriptive study design was adopted to describe and review the EIP programme, patient demographics and treatments offered in the service over a 5-year period.ResultsA total of 139 patients were accepted into the programme over the 5-year period. The mean age of onset was 30 years (median = 28, SD = 9.9), and the mean duration of untreated psychosis was 8 months (median = 2.5, SD = 15.3). Two-thirds of patients were single on initial assessment, had a history of substance misuse and were unemployed. The majority of the cohort engaged with the keyworkers and occupational therapy but did not complete the full psychological or family programmes offered. Hospital admission was required for 12% of the cohort.ConclusionsPatients experiencing their first episode of psychosis can successfully be treated in the community with appropriate professional and family support. However, deficiencies were noted in physical health monitoring, as well as in the availability and engagement with family and psychological therapies. Properly resourced early interventions in psychosis teams are necessary to deliver services at internationally recognised standards.

Abstract
Research involving substance users with psychosis has high refusal and attrition rates. Understanding participants' experiences of research participation is therefore important. Twenty-two cannabis users with schizophrenia spectrum disorders were recruited. They were involved in a randomized controlled trial exploring the effectiveness of motivational interviewing plus cognitive behavioral therapy. Semistructured interviews were conducted, and their responses were analyzed using thematic analysis. Thematic analysis identified facilitators such as therapeutic benefit, knowledge about medical conditions, awareness of own drug habits, helping others, confidentiality, rapport with researchers, desiring social contact, and views of significant others. Barriers identified were cognitive challenge, amount of assessments, duration, and discussions about the past. Based on these insights, we recommend informing participants about clinical equipoise, confidentiality, and demands of the study; minimizing demands on participants; acknowledging participants' efforts; involving potential participants' significant others during recruitment; advertising research as an opportunity to help; and training researchers in building rapport.

Abstract
BACKGROUND Comorbidity is highly prevalent between substance use disorders (SUDs) and schizophrenia. This systematic review and meta-analysis estimated prevalence rates of SUDs in epidemiological and treatment-seeking patients diagnosed with schizophrenia or first episode psychosis. METHODS A literature search of Medline, EMBASE, PsycINFO and CINAHL databases was conducted from 1990 to 2017 inclusive. Prevalence of co-morbid SUDs and schizophrenia were extracted and odds ratios (ORs) were calculated using random effects meta-analysis. Combining like studies was dictated how authors reported substance use. RESULTS There were 123 included articles with a total sample size of 165,811 subjects that yielded six epidemiological studies, 11 national or state case-registry studies, 20 large cohort studies and 86 clinical studies using in- or out-patient samples. The prevalence of any SUD was 41.7%, followed by illicit drugs (27.5%), cannabis (26.2%), alcohol (24.3%) and stimulant use (7.3%). Meta-analysis showed the pooled variance of any SUD in males was 48% which was significantly higher than that for females with schizophrenia (22.1%, OR 3.43, 95% CI 3.01, 3.92). Patients with SUD had an earlier age of onset of schizophrenia. Meta-regression showed prevalence increased over time for illicit drugs but not for other substances, including alcohol. CONCLUSIONS The meta-analysis revealed that SUDs in schizophrenia is highly prevalent and rates have not changed over time. This indicates SUD are difficult to treat in this patient population and there is an urgent need for more informative studies to help develop better prevention, detection and treatment of SUDs in persons with schizophrenia and co-morbid disorders.

Abstract
Schizophrenia is a heterogenous and severe neuropsychiatric disorder that affects nearly 1% of the population worldwide. Antipsychotic drugs are the mainstay of treatment, but not all patients with schizophrenia respond to treatment with these agents. Clozapine, the first atypical antipsychotic, is a highly effective medication for patients with schizophrenia who do not respond to other antipsychotics. Although clozapine tends not to produce extrapyramidal symptoms, other side effects of the drug (e.g., agranulocytosis, myocarditis, seizures) limit its widespread use. This chapter reviews clozapine's unique clinical effects and unusual pharmacological profile. In addition to its effects in treatment-resistant schizophrenia, clozapine has been shown to decrease suicidality, which occurs at an increased rate in patients with schizophrenia. Still preliminary, but consistent data, also suggest that clozapine limits substance use in these patients, an important effect since substance use disorders are common in patients with schizophrenia and are associated with a poor outcome, including an increased risk for suicide and poor response to treatment. We have suggested, from animal studies, that clozapine's apparent ability to limit substance use may occur through its actions as a weak dopamine D2 receptor antagonist, a potent norepinephrine α-2 receptor antagonist and a norepinephrine reuptake inhibitor. Using animal models, we have built combinations of agents toward creation of safer clozapine-like drugs to reduce substance use in these patients. Future research into the mechanisms of action of clozapine toward the development of safe clozapine-like agents is of great public health importance.

Abstract
Aims and MethodWe established two ‘dual diagnosis’ community psychiatric nurse posts within community mental health teams in Lanarkshire to improve the service care for individuals with comorbidity. A questionnaire-based evaluation of the service over a 2-year period was conducted.ResultsComorbidity was under-reported by community mental health teams and under-referred to specialist addiction services. The presence of new specialist nurses enhanced the detection of comorbidity, improved staff perceptions of working with patients that misuse substances, and was associated with a clinical and functional improvement in patients over 2 years.Clinical ImplicationsOur findings support the recent trend to provide integrated care for comorbid service users within mainstream mental health services, and suggest a model of service delivery that might be more widely developed to address the concern that such users ‘fall through the gaps’ between services.

Abstract
Aims and methodTo explore the patterns of alcohol consumption and its impact on clinical outcomes in schizophrenia in low- and middle-income countries. We performed a cross-sectional survey of 315 patients with schizophrenia and calculated the prevalence of alcohol consumption and alcohol use disorder. The patients' sociodemographic profiles and clinical outcomes, including Brief Psychiatric Rating Scale (BPRS) scores, were compared between abstainers and drinkers using the χ2- andt-tests.ResultsThe 1-year prevalence of drinking, hazardous drinking and alcohol dependence was 16.8% (95% CI 12.9–21.4), 5.7% (95% CI 3.4–8.9) and 2.5% (95% CI 1.1–4.9), respectively. Male gender, single or post-marital status, higher education and being economically active were significantly associated with alcohol consumption. Alcohol drinkers were significantly more likely to be on combination psychotropics compared with abstainers. The mean total BPRS score was significantly lower in alcohol drinkers compared with abstainers. Drinking alcohol was associated with fewer deficit symptoms.Clinical implicationsCultural settings have a significant impact on the prevalence of alcohol use disorder in schizophrenia.

Abstract
BackgroundThe potential of first-episode studies in schizophrenia is maximised through systematic epidemiological, clinical and biological comparisons between homogeneous populations of the psychoses.AimsTo conduct prolonged accrual of ‘all’ cases of non-affective and affective psychotic illness on an epidemiologically complete basis.MethodWithin the region covered by Cavan–Monaghan psychiatric service (population 102 810), all putative cases of first-episode psychosis were diagnosed using DSM–IV.ResultsFrom 1995 to 2000, 69 cases of psychosis were ascertained, the incidence being 2.3-fold lower in females than in males. On resolving the ‘core’ diagnoses of schizophrenia and bipolar disorder, incidence of schizophrenia among women was 7.5-fold lower than among men whereas incidence of bipolar disorder among women was 6.6-fold lower than among men.ConclusionsThis homogeneous population, which eliminates factors associated with urbanicity and minimises confounding factors such as socioeconomic, ethnic and geographical diversity, shows a markedly reduced incidence among females both of schizophrenia and of bipolar disorder.

Abstract
Aims and MethodThe study aimed to identify the correlates of aggressive behaviour in an adult acute psychiatric ward. Over a period of 9 months, all incidents of verbal and physical aggressive behaviour exhibited by in-patients were routinely assessed using the Overt Aggression Scale.ResultsOf the 535 patients admitted during the study period, 80 (15%) were involved in a total of 124 aggressive incidents. Of these 80, 44 (55%) had a history of previous violence and 54 (68%) had a history of substance misuse. The majority of events occurred early in the hospital stay and in most cases aggression was against staff. There were significant differences between aggressive and non-aggressive patients in terms of gender and ethnicity, with the lowest rate occurring in European females.Clinical ImplicationsThese results reinforce clinical impressions, and empirical evidence, and allow risk assessment to be performed with greater confidence. The relevance of ethnicity (or more likely culture) highlights the difficulties of a ‘one size fits all’ approach to risk assessment.

Abstract
Data from 247 first-episode psychosis patients were used to explore associations between types of hallucinations and nine diverse clinical characteristics. Psychopathology was rated using the Scale for the Assessment of Positive Symptoms and Scale for the Assessment of Negative Symptoms (SANS). Childhood adversity was assessed with seven instruments; family history with an adapted version of the Family Interview for Genetic Studies; age at onset of psychosis and duration of untreated psychosis (DUP) with the Symptom Onset in Schizophrenia inventory; and insight with the Birchwood Insight Scale. Both principal component analysis-derived Auditory and Non-Auditory Hallucinations were similarly associated with delusions of influence, negative affect delusions (jealousy and sin/guilt), interpersonal childhood abuse, DUP, and insight. However, the two hallucination domains had different associations with grandiose/religious, paranoid, and somatic delusions; SANS score; childhood violence exposure; cannabis use disorders; and cocaine/other drug use disorders. Neither Auditory nor Non-Auditory Hallucinations were associated with childhood neglect, age at onset, alcohol use disorders, family history, or mode of onset of psychosis. Findings support considering hallucinations not as a unitary psychopathological construct. They represent at least two domains and are correlated in different ways with diverse clinical variables.

Abstract
BACKGROUND AND OBJECTIVES The purpose of this study was to evaluate the extent of short-term memory impairment and schizophrenia-like symptoms in heavy and systematic cannabis users and the association between the severity of abuse and the longevity of its persistent symptoms after refraining from such use. METHODS A complete psychiatric examination and a psychometric evaluation were performed in 48 solely cannabis users. Additionally, head hair samples were analyzed and the detected cannabinoids levels were correlated with the psychometric findings. RESULTS A total of 33.3% (n = 16) of the total examined cannabis users were currently imprisoned. The years of abuse ranged from 1 to 35 years and the median daily dose was 5.84.4 gr and 4.84.0 gr for prisoners (n = 16) and non prisoners (n = 32), respectively. A total of 39.6% of the users experienced hallucinations (mostly auditory), 54.2% experienced delusions (mostly ideas of reference and persecution), 85.4% had organic brain dysfunction in a test addressing visual-motor functioning and visual perception skills, and all users (100%) were found to have organic brain dysfunction in a test of visual memory immediate recall. The cannabinoid metabolite levels in the hair samples were consistent with the reported history of substance abuse and total grams of consumption for the participants below 35 years old (p < .001). Statistically elevated cannabinoids levels were observed in users with auditory hallucinations compared to users without any hallucinations (p = .019). CONCLUSIONS The existence of hallucinations, delusions, and organic brain dysfunction in heavy cannabis users seems to be associated with cannabinoid levels in hair. The continuation of persistent symptoms 3 months after the discontinuation of cannabis abuse, was a remarkable finding. SCIENTIFIC SIGNIFICANCE We provide evidence that chronic and heavy cannabis abuse results in long-lasting brain dysfunction in all users and in long-lasting schizophrenia-like psychotic symptoms in more than half of all users. These findings suggest a reevaluation of the current classification of cannabis as a "soft narcotic" which erroneously, therefore, is typically considered harmless. (Am J Addict 2017;26:335-342).

Abstract
The aim of this study was to understand which of a number of factors are most associated with psychiatric inpatient length of stay (LoS). We hypothesized that a longer LoS would be predicted by: older age, male gender, unmarried marital status, foreign nationality, more than one hospitalization, being hospitalized involuntarily, psychotic symptoms and behavioral dyscontrol at admission, discharge diagnosis of psychotic and personality disorders, not having a substance use disorder, treatment with more than one class of medications, and being discharged to a community residential facility. All admissions to the Psychiatric Inpatient Unit of Santa Maria della Misericordia, Perugia Hospital, Umbria, Italy, from June 2011 to June 2014, were included in a medical record review. Bivariate analyses were performed and a multiple linear regression model was built using variables that were associated (p < .05) with LoS in bivariate tests. The study sample included 1236 patients. In the final, most parsimonious regression model, five variables independently explained 18 % of variance in LoS: being admitted involuntarily, being admitted for thought disorders, not having a substance-related disorder, having had more than one hospitalization, and being discharged to a community residential facility. LoS on this inpatient psychiatric unit in Umbria was associated with a number of sociodemographic and clinical characteristics. Knowledge of these and other predictors of LoS will be increasingly important to, when possible, reduce the length of restrictive, costly hospitalizations and embrace community-based services.

Symptomatic and functional outcomes of substance use disorder persistence 2 years after admission to a first-episode psychosis program. Psychiatry Res 2017; 247:113-119.

Abstract
Substance use disorders (SUD) in first-episode psychosis (FEP) are highly prevalent and linked with poor outcomes. However, most longitudinal studies investigating their impacts in FEP have not reported proportions of patients who ceased SUD. Our aim was to examine the influence of SUD course on functional and symptomatic outcomes as well as service use in FEP. We performed a 2-year longitudinal study of 212 FEP patients, aged between 18 and 30 years, admitted to 2 early psychosis services in Montréal, Québec, Canada. We observed that cannabis was the first substance abused (42.9% at baseline), followed by alcohol (19.3%). The SUD rate decreased by approximately 30% during the first year. Patients with persistent SUD had worse functional outcomes (Quality of Life Scale, Social and Occupational Functioning Assessment Scale, employment), more symptoms (Positive and Negative Symptoms Scale) and heavier service use (emergency and hospitalization). SUD persistence was associated with illness severity, homelessness and cluster-B personality. Those living with their parents and financially supported by them were more likely to cease SUD. Our results indicate that SUD course was more significant than having SUD at admission; persistent SUD was associated with worse outcomes. SUD decreased during a general early psychosis intervention program (with no specialized SUD treatment). An integrated, specialized approach targeting FEP patients with predictive factors of SUD persistence during the first years of treatment might increase SUD cessation and possibly improve outcomes.

Abstract
OBJECTIVE We investigated the role of biological and psychosocial risk factors in the development of psychotic disorders with regards to immigrant status. Our hypothesis was that biological risk factors are more predictive of psychosis in non-immigrants, whereas psychosocial risk factors play a bigger role in immigrants. METHOD A retrospective audit of admissions between December 2013 and June 2014 in an Australian adult inpatient unit was conducted, focussing on patients with psychotic disorders. We analysed the association between immigrant status, and biological and psychosocial variables. RESULTS For biological risk factors, non-immigrants had significantly more family history of psychotic disorders (p = 0.021), illicit drug use (p = < 0.001) and alcohol use (p = < 0.001). For psychosocial risk factors, immigrants were more likely to have experienced a traumatic event (p = 0.022). With regards to age of index presentation, age at onset of psychotic disorder, proportion of males and dysfunctional family background, there was no significant difference. CONCLUSION Retrospective data in this report suggests that the development of psychotic disorders in immigrants and non-immigrants may be different.

Abstract
OBJECTIVES Cannabis use is prevalent among people with first episode psychosis and the epidemiology of its use in early psychosis is unclear. We performed a meta-analysis of observational studies to determine; (1) the interval between age at initiation of cannabis use and age at onset of first episode psychosis, (2) the prevalence of cannabis use at time of first episode psychosis, and (3) the odds of continuing cannabis following treatment for first episode psychosis. DATA SOURCES Search of electronic databases MEDLINE, EMBASE, PsycINFO, Web of Science and CINAHL for English-language papers using search terms (psychosis OR schizophrenia) AND (cannabis OR marijuana) IN (title OR keyword OR abstract), current to October 2014. STUDY SELECTION Studies were included if they reported on prevalence of current cannabis use in first episode psychosis cohorts. A total of 37 samples were included for meta-analysis. DATA EXTRACTION Rates of cannabis use in each sample were extracted to determine prevalence estimates. The age at initiation of regular cannabis and age at onset of psychosis were used to determine the length of cannabis use preceding psychosis. Prevalence estimates at first episode psychosis and various time points of follow-up following first episode psychosis were analysed to determine odds ratio of continuing cannabis use. Data synthesis was performed using random-effects meta-analyses. RESULTS The pooled estimate for the interval between initiation of regular cannabis use and age at onset of psychosis was 6.3 years (10 samples, standardised mean difference = 1.56, 95% confidence interval = [1.40, 1.72]). The estimated prevalence of cannabis use at first episode psychosis was 33.7% (35 samples, 95% confidence interval = [31%, 39%]). Odds of continued cannabis use between 6 months and 10 years following first episode psychosis was 0.56 (19 samples, 95% confidence interval = [0.40, 0.79]).

Abstract
Suicide is a relevant leading cause of death among patients affected by schizophrenia. Even if suicidal ideation may be present in different stages of disease, some differences have been described between the risk of suicide in patients experiencing first episode of psychosis and those with long-term schizophrenia. It is particularly higher during the first year of illness and reaches a steady decline over the following years. Suicidal ideation and attempts may also be common among subjects with subthreshold psychotic experiences. Factors associated with the risk of suicide in the early phase of schizophrenia are previous suicidal attempts and social aspects: the lack of social support and stable relationships, social drift after the first episode, and social impairment. Also, several psychotic symptoms (suspiciousness, paranoid delusions, mental disintegration and agitation, negative symptoms, depression and hopelessness, and command hallucinations) and substance abuse are associated with higher risk of suicide. It has been described that perfectionism and good levels of insight among individuals who have recently developed psychotic symptoms are significantly associated with higher numbers of suicidal attempts. Moreover, recent evidences show that prefrontal cortex-based circuit dysfunction may be related to suicide in the early stage of schizophrenia. This narrative review summarizes available evidences on suicide in the early stage of schizophrenia and deals with issues to be further studied and discussed.

Abstract
A childhood history of attention deficit hyperactivity disorder (ADHD) is common in psychotic disorders, yet prescription stimulants may interact adversely with the physiology of these disorders. Specifically, exposure to stimulants leads to long-term increases in dopamine release. We therefore hypothesized that individuals with psychotic disorders previously exposed to prescription stimulants will have an earlier onset of psychosis. Age of onset of psychosis (AOP) was compared in individuals with and without prior exposure to prescription stimulants while controlling for potential confounding factors. In a sample of 205 patients recruited from an inpatient psychiatric unit, 40% (n = 82) reported use of stimulants prior to the onset of psychosis. Most participants were prescribed stimulants during childhood or adolescence for a diagnosis of ADHD. AOP was significantly earlier in those exposed to stimulants (20.5 vs. 24.6 years stimulants vs. no stimulants, p < 0.001). After controlling for gender, IQ, educational attainment, lifetime history of a cannabis use disorder or other drugs of abuse, and family history of a first-degree relative with psychosis, the association between stimulant exposure and earlier AOP remained significant. There was a significant gender × stimulant interaction with a greater reduction in AOP for females, whereas the smaller effect of stimulant use on AOP in males did not reach statistical significance. In conclusion, individuals with psychotic disorders exposed to prescription stimulants had an earlier onset of psychosis, and this relationship did not appear to be mediated by IQ or cannabis.

Abstract
BACKGROUND There is a clear need for effective interventions to reduce cannabis use in patients with first-episode psychosis. This follow-up of a randomized trial examined whether an intervention for parents, based on motivational interviewing and interaction skills (Family Motivational Intervention, FMI), was more effective than routine family support (RFS) in reducing cannabis use in patients with recent-onset schizophrenia. METHOD In a single-blind trial with 75 patients in treatment for recent-onset schizophrenia, 97 parents were randomly assigned to either FMI or RFS. Assessments were conducted at baseline and at 3 and 15 months after the interventions had been ended. Analyses were performed on an intention-to-treat basis using mixed-effect regression models. RESULTS From baseline to the 15-month follow-up, there was a significantly greater reduction in FMI compared to RFS in patients' quantity (p = 0.01) and frequency (p < 0.01) of cannabis use. Patients' craving for cannabis use was also significantly lower in FMI at 15 months follow-up (p < 0.01). Both groups improved in parental distress and sense of burden; however, only FMI parents' appraisal of patients' symptoms showed further improvement at the 15-month follow-up (p < 0.05). CONCLUSIONS The results support the sustained effectiveness of FMI in reducing cannabis use in patients with recent-onset schizophrenia at 15 months follow-up. Findings were not consistent with regard to the long-term superiority of FMI over RFS in reducing parents' distress and sense of burden.

Abstract
BACKGROUND A lack of an aetiologically based nosology classification has contributed to instability in psychiatric diagnoses over time. This study aimed to examine the diagnostic stability of psychosis diagnoses using data from an incidence sample of psychosis cases, followed up after 10 years and to examine those baseline variables which were associated with diagnostic change. METHOD Data were examined from the ÆSOP and ÆSOP-10 studies, an incidence and follow-up study, respectively, of a population-based cohort of first-episode psychosis cases from two sites. Diagnosis was assigned using ICD-10 and DSM-IV-TR. Diagnostic change was examined using prospective and retrospective consistency. Baseline variables associated with change were examined using logistic regression and likelihood ratio tests. RESULTS Slightly more (59.6%) cases had the same baseline and lifetime ICD-10 diagnosis compared with DSM-IV-TR (55.3%), but prospective and retrospective consistency was similar. Schizophrenia, psychotic bipolar disorder and drug-induced psychosis were more prospectively consistent than other diagnoses. A substantial number of cases with other diagnoses at baseline (ICD-10, n = 61; DSM-IV-TR, n = 76) were classified as having schizophrenia at 10 years. Many variables were associated with change to schizophrenia but few with overall change in diagnosis. CONCLUSIONS Diagnoses other than schizophrenia should to be regarded as potentially provisional.

Abstract
Schizophrenia is a mental disorder characterized by a series of positive, negative or cognitive symptoms but with also the particularity of exhibiting a high rate of co-morbid use of drugs of abuse. While more than 80% of schizophrenics are smokers, the second most consumed drug is alcohol, with dramatic consequences on frequency and intensity of psychotic episodes and on life expectancy. Here we investigated the impact of light alcohol intake during adolescence on the subsequent occurrence of alcohol addiction-like behavior in neonatal ventral hippocampal lesion (NVHL) rats, a neurodevelopmental model of schizophrenia. Our findings demonstrated an increased liability to addictive behaviors in adult NVHL rats after voluntary alcohol intake during adolescence. NVHL rats displayed several signs of alcohol use disorder such as a loss of control over alcohol intake and high motivation to consume alcohol, associated with a higher resistance to extinction. In addition, once NVHL rats relapsed, they maintained higher drinking levels than controls. We finally showed that the anti-addictive drug naltrexone is efficient in reducing excessive alcohol intake in NVHL rats. Our results are in accordance with epidemiological studies underlying the particular vulnerability to alcohol addiction after adolescent exposure to alcohol and highlight the fact that schizophrenic subjects may be particularly at risk even after light alcohol consumption. Based on these results, it seems particularly relevant to prevent early onset of alcohol use in at-risk subjects and thus to reduce the incidence of co-morbid alcohol abuse in psychotic patients.

Abstract
Considerable variation has been observed in the course and outcome of schizophrenia. With regard to epidemiology of schizophrenia, papers from different Asian countries have reported findings which are in contrast with literature from the western countries. In this background we undertook a narrative review of literature regarding course and outcome of schizophrenia in Asian countries. We conducted Medline search for English-language papers on long-term course and outcome of schizophrenia conducted in Asia in the past 3 decades. We also reviewed data pertaining to Asian countries from the World Health Organization's International Study of Schizophrenia (ISoS). In addition to ISoS, we retrieved 14 reports from 9 Asian countries. While ISoS used comparable methodology across the countries, non-ISoS studies differed substantially in their aims, sampling, follow-up rates and assessment tools used for studying the course and outcome. Overall, the percentage of patients who experienced clinical and functional outcome in the Asian countries were largely comparable to those in the western studies. We observed significant variations in the long-term outcome and mortality in schizophrenia even among the Asian countries. In conclusion, there is substantial variation in the long-term course and outcome and mortality across different Asian countries. The reason for this remains unexplored. Cross-national studies exploring biological and cultural explanations for this variation may provide clues, which may have heuristic, translational and public-health significance.

Abstract
OBJECTIVE Only a few studies in patients with first-episode psychosis have included gender in the study hypothesis or considered this a primary study variable. The aim of this study was to explore the influence of gender in the pattern of substance use in patients with first-episode psychosis. METHODS This is a sub-analysis of a randomized open clinical trial that compared 1-year treatment retention rates of patients with first-episode psychosis randomized to haloperidol, olanzapine, quetiapine, risperidone, or ziprasidone. Our sub-analysis included 85 men and 29 women. RESULTS Substance use was relatively high among these patients and differed significantly by gender. Men were more likely to use substances overall than women (89.4% for men vs. 55.2% for women), χ(2) = 16.2, df = 1, p <.001, and were also more likely to use alcohol (χ(2) = 13, df = 1, p <.001), cannabis (χ(2) = 9.9; df = 1, p <.002), and cocaine (χ(2) = 10.3; df = 1, p <.001), compared to women. While there were no gender differences in age at first consumption of alcohol or cocaine, men were significantly younger at first consumption of cannabis (M = 16.08 years, SD = 2.1) than women (M = 18.0 years, SD = 3.8), F(1, 59) = 5, p <.02. When analyzed separately by gender, women showed no significant differences in the influence of number of substances used on age at onset of psychosis, F(3, 29) = 1.2, p =.30. However, there was a significant difference among men, with earlier onset of psychosis noted in men consuming multiple substances; F(4, 85) = 5.8, p <.0001. Regarding prediction of age at onset of psychosis, both male gender and the use of a higher number of substances significantly predicted an earlier age at onset of psychosis. CONCLUSIONS Our study provides some evidence of gender differences in the pattern of substance use in patients with first-episode psychosis, suggesting the possible need for gender-specific approaches in the interventions performed in these patients. This study is registered as #12610000954022 with the Australian New Zealand Clinical Trials Registry (www.anzctr.org.au).

Abstract
Aims and method The study reports findings of an investigation into the presence of severe and enduring mental health problems within the four statutory and non-statutory teams of an established substance misuse treatment partnership. Results Of a total of 772 clients in the four teams surveyed, 69 (8.9%) were identified as having severe and enduring mental health problems and problem substance use in the past 12 months. Alcohol was the most prevalent substance used by this predominantly male group. Different rates were found across the four teams, with higher numbers in the non-statutory teams. The clients displayed significant levels of self-harm and suicide risk and were responsible for 131 acute service contacts over the past 12 months. Clinical implications Clients with severe and enduring mental health problems engaged with substance misuse services display high levels of complex need. It is important to identify the best and most effective service response to this group.

Abstract
BACKGROUND Cannabis use is high amongst young people who have recently had their first episode of psychosis, and is associated with worse outcomes. To date, interventions to reduce cannabis consumption have been largely ineffective, and it has been suggested that longer treatment periods are required. METHOD In a pragmatic single-blind randomized controlled trial 110 participants were randomly allocated to one of three conditions: a brief motivational interviewing and cognitive behavioural therapy (MI-CBT) intervention (up to 12 sessions over 4.5 months) with standard care from an early intervention service; a long MI-CBT intervention (up to 24 sessions over 9 months) with standard care; or standard care alone. The primary outcome was change in cannabis use as measured by Timeline Followback. RESULTS Neither the extended nor the brief interventions conferred benefit over standard care in terms of reductions in frequency or amount of cannabis use. Also the interventions did not result in improvements in the assessed clinical outcomes, including symptoms, functioning, hospital admissions or relapse. CONCLUSIONS Integrated MI and CBT for people with cannabis use and recent-onset psychosis does not reduce cannabis use or improve clinical outcomes. These findings are consistent with those in the published literature, and additionally demonstrate that offering a more extended intervention does not confer any advantage. Many participants were not at an action stage for change and for those not ready to reduce or quit cannabis, targeting associated problems rather than the cannabis use per se may be the best current strategy for mental health services to adopt.

Abstract
In the present study we sought: 1) to estimate the frequency of substance use disorders (SUD), and 2) to investigate whether there is a mere association between diagnosis and SUD in a large cohort of patients with severe psychiatric disorders representative of the usual setting and modality of care of a psychiatric emergency service in a geographically well-defined catchment area in Italy, independent of sociodemographic features, anamnestic data and clinical status. The study was conducted between January 2007 and December 2008. The following rating scales were performed: the Clinical Global Impression-Severity (CGI-S), the Global Assessment of Functioning scale (GAF) and the Brief Psychiatric Rating Scale (BPRS). Factors found to be associated (p<0.05) with SUD[+] in the univariate analyses were subjected to multilevel logistic regression model with a backward stepwise procedure. Among 848 inpatients of our sample 29.1% had a SUD codiagnosis. Eleven factors accounted for 30.6% of the variability in SUD[+]: [a] a Personality Disorder diagnosis, [b] a Depressive Disorder diagnosis, [c] male gender, [d] previous outpatient contacts, [e] single marital status, [f] no previous psychiatric treatments, [g] younger age, [h] lower scores for BPRS Anxiety-depression and [i] BPRS Thought Disturbance, [l] higher scores for BPRS Activation and [m] BPRS Hostile-suspiciousness. The findings are important in identifying (1) the complexity of the clinical presentation of SUD in a inpatients sample, (2) the need for collaboration among health care workers, and (3) the need to develop and apply treatment programs that are targeted at particular risk groups.

Abstract
AbstractObjectives:To outline the limitations of traditional studies of outcome in schizophrenia and to review the findings arising from ‘first episode’ psychosis studies.Method:An extensive literature search was performed and relevant papers were examined and analysed.Results:Current knowledge regarding outcome predictors in schizophrenia has primarily been derived from a series of ‘consecutive admission’ and ‘long-term follow-back’ studies. However, methodological considerations may limit the generalisability of these studies' findings. The prospective evaluation of first episode cohorts has advanced our knowledge regarding the relative importance of premorbid and intercurrent factors in determining outcome in schizophrenia.Conclusions:To date, the ‘first episode’ strategy has highlighted some potentially clinically modifiable outcome predictors. These findings may open the way for targeted introduction of measures aimed at preventing poor outcomes in schizophrenia.

Abstract
AbstractObjectives: To investigate the extent and quality of substance use history taking by trainee psychiatrists.Method: A retrospective clinical casenote audit of admissions to an acute inner city psychiatric unit during three randomly selected months. Data on substance use history taking was recorded by means of a specially designed study checklist.Results: In almost three-quarters (45, 73%) of admission episodes trainee psychiatrists had made some mention of substance misuse. However, substance use history taking often occurred subsequent to the initial clinical assessment and varied greatly in quality.Conclusions: The need for a brief, standardised substance use screening questionnaire, easily incorporated into the existing psychiatric interview format is highlighted.

Abstract
AIM In the literature, there is evidence suggesting an association between substance use and psychosis. However, little is known about substance use in those who may be in the pre-psychotic phase, that is, those who are putatively prodromal are considered to be at clinical high risk (CHR) of developing psychosis. METHODS We conducted a review of publications measuring patterns and rates of substance use in CHR for psychosis individuals and the effects on the transition to psychosis. RESULTS Of 5527 potentially relevant research papers, 10 met inclusion criteria of CHR subjects and specifically mentioned substance use in the sample. The results of these studies varied. Cannabis, alcohol and tobacco/nicotine were reported as the most commonly used substances. There was limited information on the changes in patterns of use over time. Two out of the ten studies found a significant association between the use of substances and subsequent transition to psychosis. In one of these studies, substance abuse was a predictor of psychosis when included as a variable in a prediction algorithm. In the other study, the abuse of cannabis and nicotine was associated with transition to psychosis. CONCLUSIONS We found limited evidence to suggest that increased rates of substance use may be associated with transition to psychosis. However, further prospective research examining the association between substance use and transition to psychosis is required before any firm conclusions can be made.

Abstract
Despite the well-documented association between aggression and NSSI among adolescents, relatively little research has been conducted on the mechanisms underlying this relationship. The purpose of this study was to investigate potential socio-cognitive mechanisms through which aggression and NSSI are related. Participants were 186 adolescents (ages 13-18) recruited from a psychiatric inpatient facility in the northeastern United States. According to teen report, 57.5% of the sample endorsed NSSI in the previous year. Mediation was tested using the modern bootstrapping technique described by Hayes, using 5000 resamples with replacement, including sex and depression diagnosis as covariates. Results demonstrated that greater negative self-talk, a more negative cognitive style, and lower perceived family support were all significant mediators of the relationship between aggression and greater frequency of NSSI, whereas perceived social support from friends was not a significant mediator. Limitations, clinical implications, and future research directions of the current research are discussed.

Abstract
OBJECTIVE To understand the experiences that people with early psychosis are adjusting to and their perceived barriers to recovery. METHOD Semi-structured interviews were conducted with eight participants. Grounded Theory was applied to the design and analysis. Sampling and coding ceased when saturation of the data was reached. Respondent validation was sought from participants. RESULTS A theoretical model was developed using Strauss and Corbin's (1998) framework. A core category of distress was elicited, which was evident in all participants' accounts of their recovery. Overall six main categories were identified and it was proposed that individuals were adjusting to the distress of past experiences, uncertainty, a challenged identity, being in a psychiatric system, the reaction of others and social disadvantage. CONCLUSIONS Recovery from the distress and trauma of early psychosis does not simply involve adjustment to and recovery from a single experience or set of symptoms. The results are discussed in relation to trauma, developmental, and social inequality frameworks. Specific implications for clinical practice include incorporating the findings within formulations, developing interventions that focus on trauma, identity, and uncertainty as well as addressing the social and systemic issues identified.

Abstract
OBJECTIVE We conducted a comparative analysis of gender differences in patients with primary psychotic disorders with concurrent substance use and in those with substance-induced psychoses. METHODS A total of 385 individuals admitted to psychiatric emergency departments with early-onset psychosis and recent substance use were interviewed at baseline and at six-month intervals for two years. Using a standardized research diagnostic assessment instrument, we classified patients at baseline into primary and substance-induced psychosis groups and analyzed the effects of gender on demographic, family, and clinical characteristics at baseline, the interaction of gender and diagnosis, and gender main effects on illness course, adjustment, and service use over the two-year follow-up period. RESULTS Women had better premorbid adjustment, less misattribution of symptoms, and a later age at onset of regular drug use compared to men. Women, however, showed greater depression and histories of abuse compared to men. Men had greater arrest histories. No interactions between gender and diagnosis were significant. Both genders in the primary and substance-induced psychosis groups showed clinical and functional improvement over the follow-up period despite the overall minimal use of mental health and substance abuse treatment services. CONCLUSIONS Women and men with psychosis and substance use differ on several dimensions. Our findings suggest the need for gender-specific treatment programming across both diagnostic groups.

Abstract
OBJECTIVES To examine the prevalence of substance use among treatment naïve patients with first episode psychosis presenting to a psychiatry outpatient clinic in India. METHODS The study sample consisted of 139 first episode treatment naïve patients with psychosis from in and around Bangalore, a city in South India. Self as well as informant-reported data on type, use and duration of substance use as well as the severity of psychotic symptoms were collected using structured instruments. Urine toxicology screen was also conducted for six common drugs of abuse. Breath alcohol analysis was performed in all patients. RESULTS Acute and transient psychosis was the most common diagnosis (42.4%). Overall, 20% of the population reported current substance use disorder (excluding nicotine). Current alcohol dependence was diagnosed among 17.3%, whereas cannabis dependence in 3.6%. Life time as well as current use of cannabis was less than 6%. While one patient reported inhalant abuse none reported use of amphetamine or opioids. There was very high concordance between reported drug use and urine toxicology screen. CONCLUSION The use of illicit drugs is substantially less among first episode drug naïve patients with psychosis in an Indian urban clinical setting compared to rates reported from developed countries like North America, Canada and UK.

Abstract
Although several papers reported a wide range of negative outcomes among patients with both schizophrenia and Substance Use Disorder (SUD), only a few studies evaluated the impact of SUD on psychopathology and thus on the length of first-hospitalization. The aim of the present study was to compare clinical expression of first-episode of schizophrenia between inpatients with and without SUD, giving close attention to the length of stay. One hundred and thirty inpatients at first-episode of schizophrenia were assigned to either SUD or not SUD group depending on SUD diagnosis and were assessed through BPRS at admission, during hospitalization and at discharge. Cross-sectional and longitudinal statistical analysis were performed to investigate differences between groups and also a linear regression was used to evaluate relationship between length of stay and BPRS scores. SUD group showed more disorganization at admission, less marked improvement of symptoms (disorganization, thought disturbance, anergia), and longer hospital stay than not SUD group. Moreover BPRS total score during hospitalization was a significant positive predictor for length of stay. Taken together, these findings suggest that SUD patients have a more severe and drug-resistant expression of schizophrenia, hence, they need longer treatment to achieve the overall symptoms improvement required for discharge.

Abstract
BACKGROUND Substance misuse is a well-recognized co-morbidity to psychosis and has been linked to poor prognostic outcomes in patients. Researchers have yet to investigate the difference in rates and characteristics between first-episode Substance Induced Psychosis (SIP) and primary psychosis. We aimed at comparing patients with SIP to primary psychosis patients with or without substance misuse at baseline. METHODS Thirty SIP patients, 45 primary psychosis patients with substance misuse (PS) and 66 primary psychosis patients without substance misuse (PNS) in a well-defined Norwegian catchment area were included from 2007-2011. Assessments included symptom levels (PANSS), diagnostic interviews (SCID), premorbid function scale (PAS) and global functioning (GAF f/s). RESULTS Treated incidence for SIP was found to be 6.5/100 000 persons per year, 9.7/100 000 persons per year for PS and 24.1/100 000 persons per year for PNS (15-65 yrs). Patients who had substance misuse (PS and SIP) were more likely to be male. Duration of Untreated Psychosis (DUP) was significantly shorter in the SIP group (5.0 wks., p = 0.003) and these had more positive symptoms on the PANSS (p = 0.049). SIP patients also did poorer on early youth academic levels on the PAS. CONCLUSIONS Yearly treated incidence of SIP is 6.5/100 000 persons per year in a Norwegian catchment area. SIP patients have short DUPs, are more likely to be male, have more positive symptoms at baseline and poorer premorbid academic scores in early adolescence. Follow-up will evaluate stability of diagnosis and characteristics.

Abstract
Although non-suicidal self-injury (NSSI) and suicide attempts (SA) frequently co-occur among youth, there is increasing evidence that both the risk factors and the phenomenology of the behaviors are distinct. This study examined how individuals who engage in NSSI only, individuals who attempt suicide only, and those who have histories of both NSSI and at least one suicide attempt may differ in terms of cognitions and perceived social support. Participants were 185 adolescents (78.1 % female) between the ages of 13 and 18 recruited from a psychiatric inpatient facility in the northeastern United States. One hundred forty-eight teens were identified with a history of self-injurious behavior and divided into three groups: NSSI only (n = 45), SA only (n = 24) or both NSSI and SA (NSSI+SA; n = 79). Analyses showed that the NSSI+SA group exhibited more cognitive errors, negative self-statements, and negative views of self, world, and future, as well as less perceived familial support than either the NSSI or SA only groups. There were no differences between groups on perceived support from teachers or peers. No significant demographic or diagnostic differences were found between the NSSI and SA groups. Limitations and clinical implications of the current research are discussed.

Abstract
The nature of the relationship between cannabis use (CU) and psychosis is complex and remains unclear. Researchers and clinicians remain divided regarding key issues such as whether or not cannabis is an independent cause of psychosis and schizophrenia. This paper reviews the field in detail, examining questions of causality, the neurobiological basis for such causality and for differential inter-individual risk, the clinical and cognitive features of psychosis in cannabis users, and patterns of course and outcome of psychosis in the context of CU. The author proposes two major pathways from cannabis to psychosis based on a differentiation between early-initiated lifelong CU and a scenario where vulnerable individuals without a lifelong pattern of use consume cannabis over a relatively brief period of time just prior to psychosis onset. Additional key factors determining the clinical and neurobiological manifestation of psychosis as well as course and outcome in cannabis users include: underlying genetic and developmental vulnerability to schizophrenia-spectrum disorders; and whether or not CU ceases or continues after the onset of psychosis. Finally, methodological guidelines are presented for future research aimed at both elucidating the pathways that lead from cannabis to psychosis and clarifying the long-term outcome of the disorder in those who have a history of using cannabis.

Striatal dopamine release in schizophrenia comorbid with substance dependence. Mol Psychiatry 2013; 18:909-15. [PMID: 22869037 PMCID: PMC4128915 DOI: 10.1038/mp.2012.109] [Citation(s) in RCA: 72] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2012] [Revised: 06/04/2012] [Accepted: 06/12/2012] [Indexed: 11/23/2022]
Abstract
Dopamine (DA) has a role in the pathophysiology of schizophrenia and addiction. Imaging studies have indicated that striatal DA release is increased in schizophrenia, predominantly in the precommissural caudate (preDCA), and blunted in addiction, mostly in the ventral striatum (VST). Therefore, we aimed to measure striatal DA release in patients with comorbid schizophrenia and substance dependence. We used [(11)C]raclopride positron emission tomography and an amphetamine challenge to measure baseline DA D2-receptor availability (BPND) and its percent change post-amphetamine (ΔBPND, to index amphetamine-induced DA release) in striatal subregions in 11 unmedicated, drug-free patients with both schizophrenia and substance dependence, and 15 healthy controls. There were no significant group differences in baseline BPND. Linear mixed modeling using ΔBPND as the dependent variable and striatal region of interest as a repeated measure indicated a significant main effect of diagnosis, F(1,24)=8.38, P=0.008, with significantly smaller ΔBPND in patients in all striatal subregions (all P ≤ 0.04) except VST. Among patients, change in positive symptoms after amphetamine was significantly associated with ΔBPND in the preDCA (rs=0.69, P=0.03) and VST (rs=0.64, P=0.05). In conclusion, patients with comorbid schizophrenia and substance dependence showed significant blunting of striatal DA release, in contrast to what has been found in schizophrenia without substance dependence. Despite this blunting, DA release was associated with the transient amphetamine-induced positive-symptom change, as observed in schizophrenia. This is the first description of a group of patients with schizophrenia who display low presynaptic DA release, yet show a psychotic reaction to increases in D2 stimulation, suggesting abnormal postsynaptic D2 function.

Sara G, Burgess P, Malhi GS, Whiteford H, Hall W. Differences in associations between cannabis and stimulant disorders in first admission psychosis. Schizophr Res 2013; 147:216-22. [PMID: 23684162 DOI: 10.1016/j.schres.2013.04.017] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2012] [Revised: 03/24/2013] [Accepted: 04/15/2013] [Indexed: 11/25/2022]
Abstract
BACKGROUND Substance use in early psychosis is associated with male gender and earlier onset. Evidence about other correlates of substance use is less consistent. Stimulants (e.g. methamphetamine, cocaine) may precipitate psychosis. However the associations of stimulant disorders in early psychosis are difficult to examine because of lower prevalence and overlap with cannabis disorders. METHODS Hospital records were used to identify 9919 persons aged 15-29 with a first hospital admission with psychosis in New South Wales (NSW), Australia. Correlates of illicit drug disorders, cannabis disorders and stimulant disorders were examined using univariate and multivariate logistic regression. RESULTS Half of first psychosis admissions had comorbid substance diagnoses. Cannabis and stimulant disorders were increased more than ten-fold compared to the age-matched Australian population. Stimulant disorders were equally common in women and men and associated with urban location, social advantage and older age at first admission. Cannabis disorders were associated with male gender, younger age and non-metropolitan location. Diagnoses of drug-induced psychoses were more strongly associated with stimulants than with cannabis. Compared to people with cannabis diagnoses alone, those with both cannabis and stimulant disorders were older, more likely to have a diagnosis of drug-induced psychosis and more likely to have comorbid alcohol disorders. CONCLUSIONS Cannabis is the most commonly used substance in psychosis, and the associations of illicit drug use in psychoses are largely those of cannabis disorders. There are significant differences between the personal, socio-economic and diagnostic correlates of cannabis and stimulant disorders in young people with first admission psychosis.

Abstract
UNLABELLED Studies and meta-analyses investigating the influence of substance use disorder (SUD) (substance abuse or dependence) on psychopathology and neurocognitive function in schizophrenia patients have revealed controversial results. Most studies did only have small samples and did not focus exclusively on first-episode schizophrenia patients. METHOD In a post-hoc analysis of the European First Episode Schizophrenia Trial (EUFEST) psychopathology and cognitive performances of patients with (FE-SUD, N=119, consisting of N=88 patients with persisting SUD at baseline and N=31 patients with previous SUD) and without SUD (FE-non-SUD, N=204) were compared at baseline and 6 months follow-up. Neurocognitive assessment included the Rey Auditory Verbal Learning Test (RAVLT); Trail Making Tests A and B (TMT), Purdue Pegboard and Digit-Symbol Coding. RESULTS In total 31.1% of patients reported SUD, and 22.2% of patients used cannabis. There were no significant differences between patients with and without SUD concerning PANSS scores, extrapyramidal motor symptoms or neurocognitive measures except better performance in psychomotor speed (TMT-A, p=0.033, Cohen's d=0.26) in patients with SUD at 6 months follow-up. Interestingly, SUD patients with ongoing substance use at follow-up showed elevated positive symptoms (PANSS positive score, p=0.008, Cohen's d=0.84) compared to those who abstained. PANSS scores at baseline were increased in patients with an onset of SUD before the age of 16 years. In addition we found a correlation between longer duration of cannabis use and higher cognitive performance as well as reduced symptom improvement and more extrapyramidal motor symptoms in patients with higher frequency of cannabis consumption. CONCLUSIONS FE-SUD and FE-non-SUD show similar psychopathology and neuropsychological performances at baseline and during the first 6 months of antipsychotic treatment.

Screening for substance use disorders in first-episode psychosis: implications for readmission. Schizophr Res 2013; 146:125-31. [PMID: 23517662 PMCID: PMC4390132 DOI: 10.1016/j.schres.2013.02.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2012] [Revised: 02/05/2013] [Accepted: 02/24/2013] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Screening of substance use may prove useful to prevent readmission after the first episode of psychosis. The aim of the present study was to evaluate the influence of drug use on readmission risk in a first-episode psychosis sample, and to determine whether the cannabis/cocaine subscale of the Dartmouth Assessment of Lifestyle Inventory (DALI) is a better predictive instrument than urinary analysis. METHODS After admission, first-episode psychotic patients were interviewed for substance use and assessed with the DALI scale. They also underwent blood and urine sampling. Time to readmission was studied as a dependent outcome. The Kaplan-Meier estimator was applied to estimate the survival curves for bivariate analysis. The Cox proportional hazards model for multivariate analysis was assessed in order to control for potential confounders. ROC curve and validity parameters were used to assess validity to detect readmission. RESULTS Fifty-eight patients were included. The DALI cannabis/cocaine subscale and urinalysis were associated with increased readmission risk in survival curves, mainly the first five years of follow-up. After controlling for potential confounding variables for readmission, only the DALI cannabis/cocaine subscale remained as a significant risk factor. In terms of validity, the DALI cannabis/cocaine subscale was more sensitive than urinalysis. Alcohol assessments were not related to readmission. CONCLUSIONS The findings demonstrated that a quick screening self-report scale for cannabis/cocaine use disorders is superior to urinary analysis for predicting readmission. Future research should consider longitudinal assessments of brief validated screening tests in order to evaluate their benefits in preventing early readmission in first-episode psychosis.

Craving for cannabis in patients with psychotic disorder, their non-affected siblings and healthy controls: psychometric analysis of the obsessive compulsive drug use scale. Int J Methods Psychiatr Res 2012; 21:286-300. [PMID: 22961922 PMCID: PMC9621299 DOI: 10.1002/mpr.1362] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2010] [Revised: 04/28/2011] [Accepted: 05/18/2011] [Indexed: 01/19/2023] Open
Abstract
Cannabis use is more common in individuals with non-affective psychotic disorder and their siblings compared to healthy controls. As cannabis use is associated with a greater risk to develop psychotic disorder and an adverse outcome in those who already developed psychosis, it is important to know the role of craving in continued cannabis use and relapse in these vulnerable subjects. Therefore, we examined the validity of the Obsessive Compulsive Drug Use Scale for cannabis (OCDUS-CAN) in patients with non-affective psychotic disorder, their siblings, and healthy controls who all used cannabis in the past year. Simultaneous component analysis (SCA) was used to determine component weights that optimally explained the (co)variance of the OCDUS-CAN variables in these different populations simultaneously. A three-component SCA solution explained 74.2 % of the total variance, and consisted of well-interpretable subscales that could be best described as craving/urge, resistance, and impact. Reliability of the subscales was good. The three subscales significantly discriminated between frequent and infrequent cannabis users. Patients scored higher on the craving/urge and impact scale than siblings and controls, which could be related to primary and secondary symptoms of their disorder. The OCDUS-CAN is well suitable for people with or without vulnerability for psychotic disorder.
