AbstractThe neuropsychological outcome and Health Related Quality of Life (HRQOL) after SAH have been largely believed to be unrelated to the location of the ruptured aneurysm. This notion needs verification due to the contemporary availability of more sensitive neuropsychological test batteries and more recent clinical observations of deviant behaviour after SAH. To this end, we compared patients with ruptured aneurysms on respectively the anterior communicating artery (ACoA) (n = 24) or middle cerebral artery (MCA) (n = 22). All patients underwent an extensive neuropsychological examination, clinical interview and answered questionnaires 12 months after SAH. We found mild to moderate discrepancies from population norm in test scores on a number of areas of cognitive functioning in both patient groups, with a consistent, but statistically non-significant trend towards better functioning in MCA patients despite of the fact that patients with ruptured MCA aneurysms were initially in a poorer clinical condition and more often had intracranial haematomas. We observed slight reductions in executive functions, on the first conditions on the Delis-Kaplan Executive Functioning System (D-KEFS) tests, and some measures of memory functions in the ACoA patients. ACoA patients seemed to have problems with initiation of problem solving behaviour. None of the patient groups scored for apathy and depression. Some measures of HRQOL were equally reduced as compared to the population norm in both groups. ACoA patients remained longer on sick-leave compared to MCA patients.
