Abstract

To evaluate long-term cognitive consequences of subarachnoid hemorrhage with good outcome and the opinion of patients and their relatives about these consequences. The study included 10 patients surgically treated for subarachnoid hemorrhage due to the rupture of aneurysm of the anterior communicating artery 2 or more years earlier, and 10 age- and sex-matched healthy controls. The preoperative and postoperative course in the patients was uneventful. Clinical and psychosocial factors and cognitive status of the patients were assessed by use of checklists and neuropsychological tests for executive functions, attention, and memory, and event-related potential recordings (waves P3a and P3b) with tree-stimulus auditory oddball paradigm, which was also performed in healthy controls. The number of reported cognitive problems negatively correlated with the patients' level of community integration (rho range, -0.22 to -0.75). The average neuropsychological results ranged between the 12th and 46th percentile. Impaired results were found in 7 patients across different tests and were most frequent for visual memory, followed by verbal memory and executive functions. A clear decline in cognitive functioning was observed in 3 patients. Neit...Continue Reading
