Watershed infarction associated with dementia and cerebral atrophy

Abstract

A 63-year-old man was admitted with progressive left hemiparesis and left homonymous hemianopsia of 1 month's duration. During the 2 months before admission, he had suffered from slowly progressive dementia. The diagnosis of right-sided watershed (WS) infarction was made.He exhibited slow progression of dementia and cerebral atrophy during the period of observation after discharge. There was a positive relationship between cerebral atrophy and the degree of dementia. In the present case, WS infarction caused by right internal carotid artery occlusion might be related to dementia and cerebral atrophy.

“…They include the diffuse anoxic-ischemic encephalopathy [27] secondary to acute diffuse cerebral hypoperfusion (after cardiac arrest for example) and focal lesions in cerebral regions of selective vulnerability promoted by the presence of severe atherothrombotic stenosis or occlusion of large arteries [28]. …”
