Abstract
Objective
To estimate the cognitive function of subarachnoid hemorrhage patients with negative digital subtraction angiography (DSA), and analyse its relevant factors and clinical characteristics.
Methods
96 subarachnoid hemorrhage patients were selected, and the disease condition were classfied into different grades by Fisher scale, Hunt-Hess scale and the cognitive function were estimated by mini-mental state examination(MMSE), then calculated its incidence, analysed the relationship between the classification and cognitive impairments.
Results
The incidences of cognitive impairment in subarachnoid hemorrhage patients with negative DSA were 51.04%. Cognitive impairment was closely related to Hunt-Hess and Fisher grade (P<0.01).
Conclusion
Subarachnoid hemorrhage patients with negative DSA exist different extent of cognitive impairment.The higher Hunt-Hess or Fisher grade, the more serious cognitive impairment.
