Assessment of hemodynamic disturbances in aphasic patients by transcranial Doppler ultrasonography.
The author presents a study of Doppler cerebrovascular ultrasonography carried out in 38 aphasie patients (forms ranging from transient speech disturbances to severe, persistent disturbances of motor, sensory or mixed aphasia) after ischemic or hemorrhagic stroke. In these cases, the clinical symptoms were dominated by speech impairment and neurological deficits (mainly pyramidal), of low intensity or transient. The angiographic study revealed stenotic or occlusive disturbances at various levels of the cerebral arterial trunks. The prevalence of some clinical aspects of aphasia correlated with Doppler velocimetric images is discussed and the use of transcranial Doppler method in idiopathic aphasia, possible consequence of a transient ischemic attack, is suggested.
