Numerous authors point out the need to analyze particular subtypes of the disorder separately (e.g., those with predominantly positive or negative symptoms ). Ĭurrently, there is ongoing debate as to whether distinct types of schizophrenia can be linked with specific executive disorders. Investigating the nature of executive dysfunction is very important, especially due to the fact that they affect as many as 1% of the general population, regardless of country or cultural background, causing significant impairment in the social, professional, and family life of patients and leading to profound disability. #Taskpaper sort by alphabetical order manualAlthough executive dysfunction is not included in the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5), the international group of experts who authored the manual define them as separate domains of cognitive impairments and indicate that they are important aspects of schizophrenia. It is worth noting that it has been claimed that executive dysfunction constitutes the most specific set of neuropsychological symptoms in schizophrenia. The cognitive deficits affect attention, verbal and episodic memory, and visuo-spatial processes. In the diagnosis of executive dysfunction, it is important to use a variety of neuropsychological methods-especially those with confirmed ecological validity-to properly recognize the underlying characteristics of the observed deficits and to implement effective forms of therapy.Įxecutive dysfunction, cognitive deficits, positive and negative symptoms, and disorganization are key psychopathological symptoms in schizophrenia they are consequences of abnormalities in the structural and functional levels in the brain. Although there is much research on brain correlates of executive impairments in schizophrenia with traditional tools, it is uncertain if these results will be confirmed with the use of ecological and VR tools. Both negative symptoms and disorganization correlate significantly with executive dysfunction as measured by traditional tools, but their relationships with measures based on ecological and VR methods are still unclear. The analysis revealed that ecological and VR tests have higher levels of verisimilitude and similar levels of veridicality compared to traditional tools. This paper aims to characterize executive dysfunction in schizophrenia by comparing ecological and virtual reality assessments with traditional tools, and to describe the neurobiological and psychopathological correlates. However, there is a lack of critical analysis comparing those tools with traditional ones. In recent years, interest has grown in measuring executive function in schizophrenia with ecological and virtual reality (VR) tools.
