Clinical Trial Summary

This prospective single-center cohort study aims to identify the incidence of cognitive dysfunction after unruptured aneurysm operation and explore the influencing factors. The primary end point is the cognitive dysfunction at 6 months after operation.The features of cognitive function, mental status, neurological function recovery, and quality of life of patients with unruptured intracranial aneurysms at different time points would be analyzed.

Clinical Trial Description

This main topics is to identify and screen the patients with unruptured aneurysm who likely to suffer from cognitive dysfunction. All examinations were administered by a trained neuropsychologist.The assessment of cognitive function and mental state would be performed before operation and 6 months after operation, with the use of Montreal Cognitive Assessment Scale (MoCA) for the cognitive function, the Hamilton Anxiety Scale (HAMA) and the Hamilton Depression Scale (HDMA) tests for the mental state. The Cognitive dysfunction at 6 months after operation would be the primary end point, and the underlying factors responsible for the declined cognitive function would be analyze. The assessment of neurological function and quality of life would be performed before operation,3 months after operation and 6 months after operation, with the use of the Modified Rankin Scale(mRS) and the Functional Activities Questionnaire(FAQ) for the neurological function, the Richards—Campbell Sleep Questionnaire(RCSQ) and the 36-item short from health survey(SF-36) tests for the quality of life. ;
