Balint's syndrome in a man with border-zone infarcts caused by atrial fibrillation.
Keywords
Abstract
A 70-year-old man showed Balint's syndrome and other signs of bilateral posterior-hemisphere dysfunction of acute onset without initial unconsciousness. A computerized tomographic scan showed bilateral infarcts in the posterior arterial border-zone areas. Clinical evidence suggests that hypotension at the onset of atrial fibrillation caused these infarcts. There was a marked difference in the time course of recovery between the left and the right infarct which demonstrated that the elements of Balint's syndrome disappeared together with the left-hemisphere symptoms while the right-hemisphere symptoms were still present.
