Changes in cerebral hemodynamics have been reported in schizophrenia and proposed as underlying the cognitive deficits seen in patients. The objective of our study was to compare changes of the cerebral blood flow velocity (BFV) during neurocognitive tasks between the patients with the first episode of psychosis and healthy controls. ⋯ Decreased middle BFV during the execution of particular neurocognitive tasks in patients with FEP, compared to control subjects might indicate impaired hemodynamic function in the prefrontal/parietal brain areas, and possibly provide an explanation of some of the observed neurocognitive deficits in patients with the first episode of psychosis.
