Theory of mind and executive functions in schizophrenia and bipolar disorder: A cross-diagnostic latent class analysis for identification of neuropsychological subtypes

Abstract

OBJECTIVE: Executive dysfunction is a common feature of schizophrenia and bipolar disorder (BP). While deficits in social cognitive abilities, including theory of mind (ToM), have been suggested to be specific to schizophrenia, available evidence suggests that there is also a significant overlap in social cognitive performances of both disorders. However, there is significant heterogeneity of executive dysfunction and ToM deficits in BP and schizophrenia. Cross-diagnostic data-driven methods can reveal potential neurocognitive subtypes characterized by relatively selective deficits in social cognition. METHODS: Neurocognitive subgroups were investigated using latent class analysis, based on ..
