title: Neurocognitive functioning in drug-naive patients with first episode of psychosis before and after treatment.
abstract: Cognitive deficit is a core feature of schizophrenia mostly grasping memory, psychomotor processing, attention, thinking, and executive functioning and is already present in the prodromal phase of the illness and is detected at the onset. Recent studies have been focused on the differentiation of cognitive functioning in relation to the diagnostic categories, which reveal cognitive heterogeneity in schizophrenia and schizophrenia spectrum disorders. The study demonstrated that along with changes in the clinical state, specifically, with reduction of psychopathological symptoms, patients with schizoaffective disorders show more positive dynamics with better chances to back up while in schizophrenia the cognitive dysfunction is more defined and less prone to improvement.
