Cognitive function, depression, and quality of life in patients with ruptured cerebral aneurysms

Background: Neuropsychiatric dysfunction is one of the most common complications after aneurysmal subarachnoid hemorrhage (aSAH). The aim of this study was to evaluate cognitive function, depression, and quality of life (QOL) in patients with aSAH. Methods: In this study, we prospectively enrolled patients with SAH due to rupture of anterior circulation aneurysms who referred to Ghaem hospital, Mashhad, Iran, and who had good function outcome [modified Rankin scale (mRS) > 2]. They underwent microsurgery or endovascular treatment. Cognitive function, depression, and QOL were evaluated 6 months after surgery with standard psychiatric examinations, including Mini-Mental State Examination (MMSE) for cognitive function, Hospital Anxiety and Depression Scale (HADS) for depression, and 36-Item Short Form Health Survey (SF-36) for QOL. Risk factors for cognitive dysfunction were assessed. Results: Fifty-three patients were entered the study. The mean of age was 50.9 ± 13.6 years. QOL and its components were affected in most patients. Fifty-five percent of patients suffered from depression. Cognitive impairment was found in 57% of patients. Older patients experienced more cognitive impairment (P < 0.001). Conclusion: Neuropsychological sequels are common in patients with aSAH, even if they classified as good functional outcome (mRS > 2). These complications could be found with appropriate neuropsychological evaluation of these patients to be managed as soon as possible.
