AIM: This study aimed to estimate the relative representation of childhood psychiatric diagnoses and use of psychotropic medication in the Danish National Birth Cohort (DNBC) compared to the general population. METHODS: The general population was identified as all childbirths in Denmark during 1998-2002 ( N=344,160). Linking the DNBC ( N=91,442) and the general population to the Danish national health registries, all children were followed until they received an ICD-10 psychiatric diagnosis, had a prescription of psychotropic medication or to the end of follow-up in 2013...

Genetic variants in CACNA1C (calcium voltage-gated channel subunit alpha1 C) are associated with bipolar disorder and schizophrenia where sleep disturbances are common. In an experimental model, Cacna1c has been found to modulate the electrophysiological architecture of sleep. There are strong genetic influences for consolidation of sleep in infancy, but only a few studies have thus far researched the genetic factors underlying the process. We hypothesized that genetic variants in CACNA1C affect the regulation of sleep in early development...

Clinical staging for schizophrenia and related disorders might provide an ideal means to overcome some limitations of the current diagnostic system and to facilitate early intervention. This study aims to retrospectively explore 1) the validity of a staging model 2) the stability of staging over time, and 3) the clinical factors associated with transition to more chronic stages. Data were derived from the Genetic Risk and Outcome of Psychosis study, a large cohort study of patients with a schizophrenia spectrum disorder...

Research on the association between schizophrenia and the quality of care and clinical outcomes of heart failure (HF) remains sparse. This nationwide study compared the quality of care and clinical outcomes of HF among Danish patients with and without schizophrenia. In a population-based cohort study, we identified 36,718 patients with incident HF with hospital contacts, including 108 with schizophrenia, using Danish registries between 2004 and 2013. High quality of HF care was defined as receiving ≥ 80% guideline-recommended process-performance measures of care...

OBJECTIVE: Kraepelin considered declining course a hallmark of schizophrenia, but others have suggested that outcomes usually stabilize or improve after treatment initiation. The authors investigated this question in an epidemiologically defined cohort with psychotic disorders followed for 20 years after first hospitalization. METHOD: The Suffolk County Mental Health Project recruited first-admission patients with psychosis from all inpatient units of Suffolk County, New York (response rate, 72%)...

Autoantibodies that bind the N-methyl-D-aspartate receptor (NMDAR) may underlie glutamate receptor hypofunction and related cognitive impairment found in schizophrenia. Exposure to neurotropic pathogens can foster an autoimmune-prone environment and drive systemic inflammation leading to endothelial barrier defects. In mouse model cohorts, we demonstrate that infection with the protozoan parasite, Toxoplasma gondii, caused sustained elevations of IgG class antibodies to the NMDAR in conjunction with compromised blood-gut and blood-brain barriers...

BACKGROUND: Psychiatric disorders are multigenic diseases with complex etiology that contribute significantly to human morbidity and mortality. Although clinically distinct, several disorders share many symptoms, suggesting common underlying molecular changes exist that may implicate important regulators of pathogenesis and provide new therapeutic targets. METHODS: We performed RNA sequencing on tissue from the anterior cingulate cortex, dorsolateral prefrontal cortex, and nucleus accumbens from three groups of 24 patients each diagnosed with schizophrenia, bipolar disorder, or major depressive disorder, and from 24 control subjects...

OBJECTIVES: Headache is the most common type of pain reported by people with schizophrenia. This study aimed to establish prevalence, characteristics and management of these headaches. METHODS: One hundred participants with schizophrenia/schizoaffective disorder completed a reliable and valid headache questionnaire. Two clinicians independently classified each headache as migraine, tension-type, cervicogenic or other. RESULTS: The 12-month prevalence of headache (57%) was higher than the general population (46%) with no evidence of a relationship between psychiatric clinical characteristics and presence of headache...

Importance: Schizophrenia is associated with widespread cognitive impairments. Although cognitive deficits are one of the factors most strongly associated with functional outcome in schizophrenia, current treatment strategies largely fail to ameliorate these impairments. To develop more efficient treatment strategies in patients with schizophrenia, a better understanding of the pathogenesis of these cognitive deficits is needed. Accumulating evidence indicates that genetic risk of schizophrenia may contribute to cognitive dysfunction...

INTRODUCTION: Schizophrenia (SCZ) and bipolar disorder (BP) are linked to multiple impairments in everyday functioning which share cognitive and symptom risk factors. Other risk factors for critical aspects of every day functioning (e.g., gainful employment; residential independence) such as physical health have not been evaluated, despite poor health in SCZ and BP. METHODS: We analyzed 20-year follow-up data from the Suffolk County Mental Health Project cohort of consecutive first admissions with a psychotic disorder to 12 psychiatric facilities in Suffolk County, NY, between September 1989 and December 1995...

BACKGROUND: Concerns exist that clozapine is underutilized in the management of treatment-resistant schizophrenia. Although a 2015 change in the US Food and Drug Administration (FDA) monitoring recommendations lowered the threshold of the absolute neutrophil count for treatment interruption from 1,500/μL to 1,000/μL and removed white blood cell count thresholds from the monitoring algorithm, the implications of this policy change on clozapine interruptions remain unknown. METHODS: We analyzed outpatient prescribing records for antipsychotic medications in the Veterans Integrated Service Network 7 (VISN 7) database between 1999 and 2012 to assess the potential impact of the recent changes in FDA neutropenia monitoring recommendations on clozapine treatment discontinuation...

non-adherence in patients with schizophrenia is the most common reason for a relapse of psychosis. In a cohort of participants in Pakistan who suffered a relapse of psychosis, we aimed to identify the principal factors associated with non-adherence, including any culture specific factors that might not be as significant in other jurisdictions. Semi-structured interviews were undertaken at four psychiatric hospitals in the Peshawar region in Pakistan with 55 participants (44 male and 11 female) diagnosed with schizophrenia, who had suffered a relapse of psychosis subsequent to treatment non-adherence...

BACKGROUND: Higher lifetime antipsychotic exposure has been associated with poorer cognition in schizophrenia. The cognitive effects of adjunctive psychiatric medications and lifetime trends of antipsychotic use remain largely unclear. We aimed to study how lifetime and current benzodiazepine and antidepressant medications, lifetime trends of antipsychotic use and antipsychotic polypharmacy are associated with cognitive performance in midlife schizophrenia. METHODS: Sixty participants with DSM-IV schizophrenia from the Northern Finland Birth Cohort 1966 were examined at 43years of age with an extensive cognitive test battery...
