Objective To study the effect of hypertension on motor function in Parkinson's disease (PD) patients with white matter lesion (WML).Methods Two hundred and nineteen PD patients with WML were divided into hypokinesia group (n=137) and non hypokinesia group (n=82).The patients were followed up for 1 year.The relationship of vascular risk factors with hypertension and hypokinesia was analyzed.Results The age was older,the incidence of hypertension,DM and lipidemia was higher,the SBP and DBP were higher in hypokinesia group than in non hypokinesia group (P＜0.01,P＜0.05).Logistics regression analysis showed that age,hypertension and DM were the risk factors for hypokinesia in PD patients with WML (OR =1.78,95 ％CI:1.43-2.14,OR =1.97,95 ％0 CI:1.49-2.52,OR =1.63,95 ％ CI:1.31-1.94).Further analysis showed that grade 2 and 3 hypertension were closely related the risk of hypokinesia in PD patients with WML(OR=1.62,95％CI:1.29-1.95;OR=2.19,95％CI:1.49-2.91).Conclusion Hypertension,especially grade 2 and 3 hypertension,can aggravate hypokinesia in PD patients with WML.

BACKGROUND AND PURPOSE: This study investigated the contribution of white-matter hyperintensities (WMH) and lacunar infarcts (LI) to the risk of Alzheimer's disease (AD) in an elderly cohort in China. METHODS: Older adults who were initially cognitively normal were examined with MRI at baseline, and followed for 5 years. WMH were classified as mild, moderate, or severe, and LI were classified into a few LI (1 to 3) or many LI (≥4). Cognitive function was assessed using the Mini Mental State Examination and the Activities of Daily Living scale. RESULTS: Among the 2,626 subjects, 357 developed AD by the end of the 5-year follow-up period. After adjusting for age and other potential confounders, having only WMH, having only LI, and having both WMH and LI were associated with an increased risk of developing AD compared with having neither WMH nor LI. Moderate and severe WMH were associated with an increased risk of developing AD compared with no WMH. Furthermore, patients with many LI had an increased risk of developing AD compared with no LI. CONCLUSIONS: Having moderate or severe WMH and many LI were associated with an increased risk of developing AD, with this being particularly striking when both WMH and LI were present.
