Language network dysfunction as a predictor of outcome in youth at clinical high risk for psychosis.
OBJECTIVES Language processing abnormalities are a hallmark feature of schizophrenia. Yet, no study to date has investigated underlying neural networks associated with discourse processing in adolescents at clinical high risk (CHR) for developing psychosis(1). METHODS Forty CHR youth and 24 demographically comparable healthy controls underwent functional magnetic resonance imaging while perfo...

We sought a symptom severity classifier that would improve psychosis risk prediction. METHODS Subjects were from two cohorts of the North American Prodrome Longitudinal Study. All subjects met Criteria of Psychosis-Risk States. In Cohort-1 (n=296) we developed a classifier that...
متن کاملImpact of substance use on conversion to psychosis in youth at clinical high risk of psychosis.
Elevated rates of substance use (alcohol, tobacco, cannabis) have been reported in people at clinical high risk (CHR) of developing psychosis and there is some evidence that substance use may be higher in those who convert to a psychosis compared to non-converters. However little is known about the predictive value of substance use on risk of conversion to psychosis in those at CHR of psychosis...
متن کاملPredictors of functional outcome in individuals at high clinical risk for psychosis at six years follow-up.
BACKGROUND The long-term functional status of subjects at ultra high risk for psychosis (HR) is relatively under investigated. This study explores baseline predictors of long-term functional outcome in HR subjects who did not convert to psychosis during a 6 years follow-up period. METHODS A total of 154 HR were followed up for an average of 6 years. The primary outcome variable was global ass...
