Transcranial Doppler Assessment of the Cerebral Circulation during Postprandial Hypotension in the Elderly

Abstract

The results of this study suggest a small, unexpected increase in resistance of the intracranial circulation following a meal in elderly people with postprandial hypotension. Although the clinical significance of this finding is not known, the occurrence of postprandial arteriolar vasoconstriction may lead to cerebral ischemia during periods of marked blood pressure decline.
