Abstract
This multiple case report presents two groups of survivors from aneurysms of the anterior communicating artery (ACoA); amnesic and non-amnesics, to examine the similarities and differences in neuropsychological profiles. All six patients were consecutive admissions to acute inpatient rehabilitation, and exhibited generally intact attention, concentration and intellectual ability. Confabulation and personality changes were observed only among the amnesic ACoA patients. However, difficulties in concept formation and perseverative responding was observed in all subjects. A neurobehavioral hypothesis addressing the underlying mechanism of the main features of the "ACoA syndrome" is presented.
