    Risk Factors for Cognitive Impairment Following Angiographically Negative Subarachnoid Haemorrhage Around the Midbrain by Liu Y, Li Z, Xu W, Zhao Z, Zhang W, Wu J

    Published 2025-03-01
    “…The logistic regression results showed that age (p = 0.031), degree of consciousness impairment (p = 0.023), Hunt–Hess grading (p = 0.019), presence of hydrocephalus (p = 0.002) and presence of ventricular haemorrhage (p = 0.021) were independent risk factors for cognitive impairment after angiographically negative SAH (p < 0.05).Conclusion: Age, degree of consciousness impairment, Hunt–Hess grade (≥ 3), concomitant ventricular haemorrhage and hydrocephalus are risk factors for cognitive function after angiographically negative SAH.Keywords: subarachnoid haemorrhage, computed tomography angiography, digital subtraction angiography, cognitive impairment…”
