ABSTRACT
OBJECTIVE: To explore the link between leucoaraiosis and recovery of neurological function in elderly patients with acute cerebral infarction. METHODS: The study included elderly patients, hospitalized with acute cerebral infarction. Magnetic resonance imaging examinations were performed before or within 5 days after admission; T1-weighted, T2-weighted, fluid-attenuated inversion recovery and diffusion-weighted imaging sequence data were collected. Using the Fazekas scale, leucoaraiosis (white matter hyperintensity [WMH]) was graded as 0 (absent), 1 (mild), 2 (moderate) or 3 (severe) for all participants. RESULTS: The study included 279 patients. WMH grades of 0, 1, 2 and 3 were seen in 27 (9.67%), 90 (32.26%), 104 (37.28%) and 58 cases (20.79%) respectively. Improvement on the National Institutes of Health Stroke Scale for neurological impairment was negatively associated with WMH grade. Patients with severe leucoaraiosis at hospital admission had worse neurological functional recovery and a higher rate of self-care incapability compared with those with mild or no leucoaraiosis. CONCLUSIONS: The results suggest that severe leucoaraiosis in elderly patients with acute cerebral infarction is associated with poor prognosis and poor recovery of neurological function.
