In this abstract we explored remote effects of cerebrovascular hemodynamic impairment on the efficiency of functional connectivity in patients with chronic, anterior circulation steno-occlusive disease. We further evaluated the correlation between network efficiency and cerebrovascular reactivity (CVR), a measure of cerebral hemodynamics.
