Cortical hypoperfusion is related to cognitive and neuropsychiatric symptoms and signs. It is suggested that disruption of the frontal-subcortical circuit or perfusion deficits by remote vascular stenosis may play an important role in patients with vascular dementia. We report a case of acute hypoperfusion dementia that showed improvement of cognitive impairment and hemodynamic recovery after stent insertion. Extensive perfusion deficits caused by carotid artery stenosis with secondary hypometabolism in the hemispheric region may be a cause of reversible vascular dementia syndrome.
Key Words: Vascular dementia, Carotid artery stenosis, Hypoperfusion
