Everyday Memory in Microsurgically Treated Patients After Subarachnoid Hemorrhage

Abstract

Background: Memory declines measured by traditional tests in patients after subarachnoid hemorrhage (SAH) are well documented. Classic examinations of memory problems sometimes do not significantly correlate with memory functions in everyday life. The objective of the study was to assess the specific type of everyday memory loss in patients after microsurgical treatment of ruptured intracranial aneurysm causing SAH.

Methods: The prospective controlled, randomized study was conducted using the specific tests for everyday memory measure with high ecological validity. All patients were operated on by the same neurosurgeon (KD). Preoperatively, patients were in a good grade (Hunt-Hess I or II), with no neurological deficit and no hydrocephalus postoperatively. Patients were tested at two phases: 15 and 45 days after microsurgery with the Rivermead behavioral memory test (RBMT) and the cognitive failure questionnaire (CFQ).

Results: We compared the results of the tests administered in subjects that underwent microdiscectomy surgery for SAH to a control group that underwent surgery for lumbar disc herniation (DH).

Conclusion: Neuropsychological assessment of operated patients who sustained SAH showed a decline, compared to the DH group, in everyday memory function. Also, we found failures in perception and motor function in operated SAH patients with a trend of cognitive recovery as time progresses.
