Insight into neurocognitive dysfunction in schizophrenia

Abstract

Insight into psychotic symptoms is typically poor in schizophrenia; however, it is not known whether insight into neurocognitive impairment is similarly impaired. Most people with schizophrenia experience cognitive dysfunction, and the deficits in attention, memory, and critical thinking have been associated with poor functional outcome. As new treatments are developed for the cognitive impairments, it will be important to know whether patients will be receptive to yet another therapy. Insight is an important factor in treatment compliance and treatment outcome; however, it is not known if patients have insight into their cognitive dysfunction. In order to assess insight into neuro cognitive dysfunction, 75 subjects were administered the Measure of Insight into Cognition-Clinician Rated, a newly created measure based on the Scale to Access the Unawareness of Mental Disorder, that assesses insight into cognitive impairment. Subjects were also administered the Brief Assessment of Cognition in Schizophrenia and Independent Living Scale-Problem Solving to objectively assess neuropsychological status and problem-solving skills needed for independent living. Results demonstrated that virtually all subjects had cognitive impairment, yet insight into their neuro cognitive symptoms was limited. This finding has potential implications for treatment programs seeking to improve cognitive functioning in schizophrenia.
