Abstract:
Objective To investigate the relationship between benign paroxysmal positional dizziness (BPPV) and cerebrovascular disease and to promotethe practice of evidence bases medicinein thediagnosis,treatment and recurrenceprevention of BPPV in the elderly.Methods A total of 80 elderly patients were consecutively recruited from the Dizziness Outpatient Clinic from January 2013 to June,2014,with 80 non-BPPV elderly individuals receiving routine physical checkups during the same period serving as the control group.Clinical characteristics,lab test results and imaging data were compared between the two groups.Single factor and multivariate logistic regression analyses were conducted to identify independent risk factors for BPPV in the elderly.Results The experimental group showed higher rates of lacunar infarction,leukoaraiosis and intracranial artery stenosis than the control group(x2 =10.180,4.606 and 3.956,respectively;P=0.001,0.032 and 0.047,respectively).The prevalences of hyperlipidemia and type 2 diabetes were higher in the BPPV group than in the control group(x2 5.013 and 6.041,respectively;P=0.025 and 0.014,respectively).Differences in number of carotid atherosclerotic plaque cases,total cholesterol,triglyceride,homocysteine and uric were found between the two groups (x2 =11.237,t=2.862,2.230 and 4.270,respectively;P=0.001,0.005,0.027 and 0.000,respectively).Multivariate logistic regression analysisfound that blood uric acid,hyperglycemia,type 2 diabetes and hypertension were independent risk factors for BPPV (OR=1.006,7.104,3.152 and 3.273,respectively;P=0.005,0.000,0.004 and 0.002,respectively).The existence of carotid atherosclerotic plaques also increased the risk of BPPV (OR =384.570,95 ％ CI:46.935～ 3151.055,P =0.000).Conclusions BPPV in the elderlyis closely associated with cerebrovascular disease and its risk factors.Therefore,it is of great clinical significance to assess cerebrovascular function and carotid atherosclerotic plaque development for improved prognosis and effective prevention of recurrence of BPPV in the elderly.
