A seven-year longitudinal study of the association between neurocognitive function and basic self-disorders in schizophrenia

Abstract

Introduction: Basic self-disorders (SDs) and neurocognitive impairments are fundamental trait-like aspects of schizophrenia spectrum disorders. There has been little research on the association between SDs and neurocognitive impairments in schizophrenia, and no longitudinal studies have investigated if they are related.
