Analysis on the correlation between hyperhomocystinemia and the incidence of senile dementia / 国际检验医学杂志

ABSTRACT

Objective To analyze the relationship between hyperhomocystinemia (HHcy) and occurrence of Alzheimer disease (AD) .Methods A total of 100 cases of elderly patients with dementia were collected ,from April 2010 to May 2013 ,and divided in‐to AD group and vascular dementia (VD) group according to patients′condition .Other 50 cases of healthy elderly individuals were collected in the control group .Levels of homocysteine (Hcy) were detected ,and the relationship between level of Hcy and occur‐rence of AD was analysed .Results Levels of Hcy in the AD group and VD group were higher than that in the control group ,and were decreased after treatment ,there were statistically significant differences(P<0 .05) .After treatment ,the scores of mini‐mental state examination(MMSE) in the AD group and VD group both were increased ,and the score of activity of daily living scale(ADL) was decreased in the AD group ,there were statistically significant differences (P<0 .05) .The level of Hcy in mild AD patients was lower than that in severe AD patients ,the difference was statistically significant (P<0 .05) .The AD odds ratio(OR) was 4 .7 ,and 95% confidence interval(CI) was 1 .76 -7 .09 .The level of Hcy in patients with AD was significantly negatively correlated with score of MMSE ,the coefficient value(r) was -0 .32 ,-0 .40 and -0 .27 in mild ,moderate and severe AD(P<0 .05) .Conclusion HHcy is an independent risk factor for the onset of AD ,so attention should be paid on high Hcy level ,in order to prevent AD .
