Correlation of enlarged perivascular space and post-stroke depression in patients with ischemic stroke

Abstract

Objective To investigate the correlation between enlarged perivascular space (EPVS) and post-stroke depression (PSD) in patients with ischemic stroke. Methods Consecutive patients with acute cerebral infarction admitted to hospital from March 2010 to March 2014 were enrolled prospectively. The patients completed head MRI examination after admission and performed EPVS grading. At 3 months after symptom onset, they performed PSD assessment according to Hamilton Depression Scale (HAMD) and Classification and Diagnostic Criteria of Mental Disorders in China, 3rd edition (CCMD-3). The relationship between EPVS and PSD was analyzed. Results A total of 249 patients were enrolled; including 62 patients (4.9%) experienced PSD at 3 months. There were significant differences in the proportions of the EPVS classification patients of the baseline National Institutes of Health Stroke Scale score (the median [interquartile range]; 4 [3-6] vs. 3 [2-5]; Z=-2.950, P=0.003), centrum semiovale (χ2=14.370, P=0.001), and periventricular (χ2=11.590, P=0.003)between the PSD group and the non-PSD group. Multivariable logistic regression analysis showed that centrum semiovale EPVS grade 2 (odds ratio [OR] 3.89, 95% confidence interval [CI] 1.59-9.56) and grade 3 (OR 3.28, 95% CI 1.04-10.33) were significantly correlated with PSD; periventricular EPVS grade 2 (OR 0.72, 95% CI 0.27-1.91) and grade 3 (OR 2.24, 95% CI 0.68-7.37) were not correlated with PSD. Conclusions Centrum semiovale EPVS is independently associated with PSD, and periventricular EPVS is not.
