Exploring relation between Cognitive perceptual deficits and Functional performance in Schizophrenia- A mini review.

Abstract

Schizophrenia is a serious mental illness that affects how a person thinks, feels and behaves. People with schizophrenia may seem like they have lost touch with reality, which causes significant distress for the individual, their family members and friends. If left untreated, symptoms of schizophrenia can be persistent and disabling. Cognitive perceptual impairment is a core feature of schizophrenia and several studies have demonstrated that it is strongly related with daily functioning and other functional outcomes. Several RCTs have demonstrated that patients with schizophrenia improve negative symptomatology after cognitive rehabilitation. The prevalence of schizophrenia affects patient’s participation in functional tasks. The aim of this review was to explore literature; published in the past 15 years in the area of cognitive perceptual deficits in schizophrenia and functional impairments caused due to it. We also explored the strategies for remediation. In this integrated mini review, published researches were reviewed including RCTs, observational studies, interventional, experimental, correlational studies, case reports and systematic reviews. To conclude, it was analyzed that dysfunctions in working memory, attention and abstract thinking and problem solving have been extensively documented in schizophrenia, which may improve slightly with remedial strategies.
