Abstract

Objectives: To investigate the relationship between the lesion location and post-stroke restless legs syndrome (RLS).

Methods: A total of 376 patients with acute cerebral infarction were recruited from Tangshan Gongren Hospital, Department of Neurology between May 2016 and May 2017, all of whom were evaluated for RLS. Established RLS was diagnosed according to the criteria of the International Restless Legs Syndrome Study Group (IRLSSG) in 2012. Neurological functions were assessed according to the National Institutes of Health Stroke Scale (NIHSS). The lesion location was evaluated with magnetic resonance imaging (MRI). The associations between the lesion location and post-stroke RLS were then analyzed by logistic regression.

Results: A total of 49 patients (13.03%) had RLS. The multivariate logistic regression model adjusting for post-stroke RLS risk factors including gender, age, history of hypertension, history of diabetes, history of stroke, smoking, drinking, body mass index (BMI), NIHSS, hemoglobin, platelet and homocysteine determined that body of caudate nucleus and pontine were significantly associated with post-stroke RLS with odds ratio (OR) of 26.26 (95% confidence interval (CI): 9.41-73.28,p < 0.001) and OR of 4.37 (95% CI: 1.24-15.34, p = 0.021). The stepwise logistic regression model with temporal lobe, parietal lobe, occipital lobe, frontal lobe, callosum, body of caudate nucleus, thalamus, lenticulo capsule, corona radiata, centrum semi-ovale and pontine as potential predictors yielded a predictor mode. The stepwise logistic regression predictor mode indicated that body of caudate nucleus and pontine predicted post-stroke RLS with similar OR to multivariate models of 23.61 (95% CI: 9.53-58.51, p < 0.001) and 4.46 (95% CI: 1.38-14.4, p = 0.012).

Conclusions: The ischemic infarcts located in body of caudate nucleus, pontine are significantly associated with post-stroke RLS. Body of caudate nucleus acute infarcts may play a role in the development of post-stroke RLS.
