Abstract
Cerebral blood flow (CBF) studies were performed in 11 patients diagnosed as having infarction in the distribution of the middle cerebral or internal carotid artery. In these patients there was a diminution in CBF and metabolism and an increase in cerebrovascular resistance. These findings generally correspond to previous CBF studies in patients with cerebrovascular disease. It is postulated that the diminution in cerebral metabolism and blood flow in focal infarction may be due to the remote effects of lessened function of parts of the brain associated with or connected to the lesion.
