    Author: Papagno C, Rizzo S, Ligori L, Lima J, Riggio A.
    Journal: J Clin Exp Neuropsychol; 2003 Feb; 25(1):24-35. PubMed ID: 12607169.
    Abstract:
    The cognitive outcome of three groups of patients, who had undergone surgery for repair of a single ruptured intracranial aneurysm, was evaluated. We assessed performance on tests of executive functions and memory in a group of 15 patients tested at least 3 months after an aneurysm of the anterior communicating artery (ACoA) and in a group of 12 patients tested in the first month after the same pathology. Acute patients were more impaired overall than chronic ones, but the two groups significantly differed on two executive and one memory test. The performance of the ACoA patients was also compared to the performance of a group of 10 patients who had undergone surgery for an aneurysm located on the posterior communicating artery (PCoA) at least 3 months before the examination. Chronic ACoA and PCoA patients significantly differed in two memory and in two executive tests performance, with posterior patients being more impaired than anterior. An unexpected finding was the impairment of semantic memory in ACoA patients.
