Abstract
Background: 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.
Subjects and methods: We recruited 46 patients with the first episode of psychosis (FEP), admitted to the University Hospital
Centre Zagreb during 2016-2017 and 41 control subjects. Transcranial Doppler ultrasonography monitoring of BFV in both middle
cerebral arteries was recorded during 25-minute long neurocognitive assessment with Phonemic Verbal Fluency test, Trial Making
Test B and Stroop test. Between every consecutive test resting periods were recorded.
Results: After the adjustment for age, sex and education by quantile regression, patients with FEP had significantly lower BFV
in middle cerebral arteries during the 3rd (
