Transcranial Doppler monitoring of middle cerebral artery during verbal stimulation in aphasic patients.

Hemodynamic changes can be noninvasively real-time monitored in stroke patients by means of transcranial Doppler sonography (TCD). The aim of this pilot study was to assess hemodynamic changes in both middle cerebral arteries (MCA) in aphasic stroke patients by means of TCD during verbal stimulation. Eight aphasic patients with stroke in the territory of the left MCA were tested by modified Boston Diagnostic Aphasia Examination (BDAE) within 3 days of stroke onset.
