Exercise therapy, cardiorespiratory fitness and their effect on brain volumes: a randomised controlled trial in patients with schizophrenia and healthy controls.

The objective of this study was to examine exercise effects on global brain volume, hippocampal volume, and cortical thickness in schizophrenia patients and healthy controls. Irrespective of diagnosis and intervention, associations between brain changes and cardiorespiratory fitness improvement were examined. Sixty-three schizophrenia patients and fifty-five healthy controls participated in this randomised controlled trial.

Neurocognitive functioning in drug-naive patients with first episode of psychosis before and after treatment.

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.
