Objective To explore the relation of essential hypertension and cognitive impairment in elderly people. Methods A total of 326 elderly patients with essential hypertention (with at least 5 years of history) from January 2011 to December 2013 were taken as observation group,and 300 healthy elderly people as the control group. The mini-mental state examination (MMSE) score were used to assessed cognitive function. Results (1)The MMSE score of hypertention patients was significantly lower than that of control group (P<0.01). The prevalence of mild cognitive impairment(MCI)of hypertention patients was higher than that of control group (P<0.01). (2)MMSE score decreased with increasing blood level (P<0.01). Increasing prevalence of MCI was found in the subjects with high grade of hypertension (P<0.01). (3)The prevalence of MCI had a significant negative correlation with the grade of hypertension,LDL level and 2-hr plasma glucose. Conclusion (1)There is a close relation between hypertention and cognitive impairment in elderly pe ople.Seriousness of cognitive impairment is associated with high blood pressure. (2)The cognitive impairment in elderly people is associated with the grade of hypertention,LDL level and 2-hr plasma glucose.
