Abstract:Objective To analyze the severity and risk factors of depression following acute ischemic stroke with large vessel occlusion (AIS-LVO). Methods The incidence and severity of depression were analyzed in 139 AIS-LVO patients. The risk factors for depression were evaluated by multivariate logistic regression analysis. Results Depression occurred in 64 (46.0%) cases, with 29.7% of mild, 46.9% of moderate and 23.4% of severe depression. NIHSS and hypersensitive C-reactive protein (hs-CRP) on admission, and basal ganglia or frontal lobe lesions were independent risk factors for depression (P<0.01 or 0.05). Conclusion The depression following AIS-LVO is commonly mild and moderate. High NIHSS and hs-CRP levels on admission, and basal ganglia or frontal lobe lesions are more prone to develop depression in AIS-LVO patients.
