Abstract

Objectives:As we have previously reported, neuropsychological function and cerebral blood flow (CBF) often decrease after surgery for unruptured aneurysms of the anterior communicating artery (ACoA) or after surgery for any unruptured cerebral aneurysms (UCA) in patients older than 65 years old but usually recovers to preoperative levels by 3 months after surgery. These findings indicate that operations for UCA are satisfactorily safe and effective, and that such studies can help determine when patients can resume activities of daily life [1]. In addition, we sometimes have opportunities to operate on asymptomatic patients with UCA combined with or without lacuna infarction. Thus, it is very important to investigate how craniotomy affects the higher brain function of these patients.
