CEREBRAL HEMODYNAMIC ALTERATIONS IN MIGRAINEASSOCIATED ISCHEMIC STROKE ACCORDING TO DOPPLER ULTRASONOGRAPHY

Abstract

Migraine-associated ischemic stroke (MAIS) represents an important and
increasingly recognized subtype of cerebrovascular pathology, predominantly affecting young
and middle-aged individuals, especially women. The pathophysiological mechanisms underlying
this condition include endothelial dysfunction, vasospasm, impaired autoregulation, and
disturbances in cerebral perfusion. Despite significant advances in neuroimaging, early
identification of hemodynamic disturbances remains a critical challenge. Doppler
ultrasonography (USDG) of cerebral vessels is a widely available, non-invasive diagnostic
method that allows real-time assessment of blood flow parameters and vascular resistance.
Its role in detecting early cerebrovascular alterations in migraine-associated stroke requires
further clarification, particularly for identifying patients at increased risk of ischemic
complications.
