Abstract

BackgroundCardiac autonomic dysfunction has been associated with cognitive impairment, but the underlying pathogenesis is complex and cerebral white matter lesions (WMLs) might be implicated.MethodsTime and frequency heart rate variability (HRV) and visual rating of WMLs were carried out in 42 patients with mild cognitive impairment.ResultsAfter adjustment for relevant demographic and clinical characteristics, including left ventricular mass, reduced HRV indices of parasympathetic (root mean square of successive difference of RR intervals, RMSSD) and sympathetic modulation (low-frequency [LF] power) were associated with increased WML score (RMSSD: B-0.30, 95% CI-0.52 to-0.08, p =. 01; LF: B-0.24, 95% CI-0.46 to-0.02, p =. 05). In a multiple-adjusted model, RMSSD was the major independent predictor of WMLs (B-0.35, 95% CI-0.57 to-0.13, p =. 002).ConclusionThe evidence for an independent association of cardiac autonomic dysfunction with WMLs might suggest its role in the pathogenesis of WMLs.
