ABSTRACT
OBJECTIVE@#To investigate the clinical features and implication of restless legs syndrome (RLS) in ischemic stroke patients.@*METHODS@#A total of 199 ischemic stroke patients were enrolled and assessed by polysomnography (PSG). RLS was identified according to criteria of International Restless Legs Syndrome Study Group. Epworth Sleepiness Scale (ESS), Mini-mental State Examination (MMSE) and Patient Health Questionnaire (PHQ-9) were used to evaluate the sleep quality, cognitive function and post-stroke depression, respectively. The National Institute of Health Stroke Scale (NIHSS) was used to evaluate the neurological function 3 months after stroke onset. Gender-and age-matched non-ischemic stroke patients with RLS (primary PLS) were selected as controls.@*RESULTS@#Twenty-two cases of RLS were identified among 199 ischemic stroke patients (11.1%). Generalized linear model and logistic regression showed that low serum ferritin level (=-133.3 mg/L, 95%-200.4--0.1, <0.01), subcortical infarction (=4.05, 95%1.15-14.18, <0.05) and female (=2.54, 95%1.04-6.23, <0.05) were identified as the risk factors of RLS in ischemic stroke patients. Compared with ischemic stroke patients without RLS, ESS increased by 4.37 (95%2.33-6.41, <0.01), PHQ-9 increased by 2.17 (95%0.39--3.94, <0.05), and reduced NIHSS from the baseline deceased by 0.97 (95%-1.79--0.15, <0.05) in ischemic stroke patients with RLS. In addition, the incidence of moderate-severe depression increased (=4.27, 95%1.40-13.10, <0.05) in ischemic stroke patients with RLS. The index of periodic leg movements of sleep (PLMS) with arousal in ischemic stroke patients with RLS was significantly higher than that in patients with primary RLS (=12.85, 95%2.04-23.67, <0.05).@*CONCLUSIONS@#RLS is common in ischemic stroke patients and has adverse influences on patients.
