First episode psychosis: register-based study of comorbid psychiatric disorders and medications before and after.

Comorbid psychiatric disorders are common in first episode psychosis. We investigated comorbid disorders before, at, and after a first hospital-treated psychosis in a naturalistic nation-wide cohort (n = 2091) with a first psychosis hospitalization between 2007 and 2011, and at ages between 16 and 25. Swedish population registers were used to identify the cohort and to collect data on diagnoses at hospitalizations and medications.

Substance use disorders before, at and after first episode psychosis hospitalizations in a young national Swedish cohort.

Background: Comorbidity between Substance use disorders (SUD) and psychotic disorders is common but the temporal relation of the first episodes of SUD and psychosis and how it affects the disorders has not been extensively investigated.

Methods: A nation-wide cohort (n = 2494) with a first hospitalization for psychosis at ages between 16 and 25 was identified. Psychiatric hospitalizations were followed from birth until up to 5 years after the first psychosis hospitalization.

First episode psychosis and comorbid ADHD, autism and intellectual disability.

Background: Comorbidity between neurodevelopmental disorders and psychotic disorders is common, but little is known about how neurodevelopmental disorders influence the presentation and outcome of first episode psychosis.

Methods: A nation-wide cohort (n = 2091) with a first hospitalization for psychosis between 2007-2011 and at ages between 16-25 at intake was identified from Swedish population registries. Comorbid diagnoses of neurodevelopmental disorders were identified at first psychosis hospitalization and for ADHD also by dispensations of psychostimulants before the first psychosis hospitalization.

Criteria for self-reported quantitative sleep characteristics of individuals who sought medical help for disturbed sleep - a survey of a representative sample of the Swedish population.

Background: The public often seeks rule-of-thumb criteria for good or poor sleep, with a particular emphasis on sleep duration, sleep latency, and the number of awakenings each night. However, very few criteria are available.

Aim: The present study sought to identify such criteria.

Medication, hospitalizations and mortality in 5 years after first-episode psychosis in a Swedish nation-wide cohort.

Aim: To investigate medication, rehospitalizations and mortality after first-episode hospital-treated psychosis.

Methods: A population-based nation-wide cohort (n = 2488) with a first hospitalization for psychosis at ages between 16 and 25 was identified. Cases were followed for up to 5 years after the first psychosis hospitalization with regard to mortality, hospitalizations and dispensations of antipsychotics and benzodiazepines.
