Functional Transcranial Doppler Sonography

IntroductionSchizophrenia is a severe mental disorder, with complex symptoms involving psychosis, negative symptoms and cognitive impairment. The Trail Making Test (TMT) has been widely used to assess attention and executive function. Functional transcranial Doppler sonography (fTCD) of basal cerebral arteries allows monitoring of aberrant cerebral hemodynamics during cognitive tasks in this patient group.ObjectivesWe assessed cerebral hemodynamics in the middle cerebral arteries (MCA) using fTCD while patients with schizophrenia and healthy subjects performed the TMT and a control task.MethodsFifteen patients with chronic schizophrenia and 15 healthy controls performed the TMT-A and -B during fTCD measurements of the MCA. Dependent measures were performance, mean cerebral blood flow velocity (MFV) and the lateralization.ResultsPatients demonstrated an overall decreased speed of solution (P = 0.002), and there was no significant effect of age. They showed a significantly increased flow pattern for the TMT-B (P = 0.005). There were no lateralization differences between diagnostic groups.ConclusionsThere was a performance deficit in patients with schizophrenia for both TMT-A and -B that fits well with results of existing literature. The aberrant hemodynamic response supports the idea that cognitive performance elicits an aberrant cerebral hemodynamic correlate. It adds to the notion that fTCD is a valuable tool to correlate psychological paradigms with brain perfusion in patients with schizophrenia.Disclosure of interestThe authors have not supplied their declaration of competing interest.
