The combined risk ratio (RR) and 95% confidence interval (CI) of the included literatures were calculated,and sensitivity analysis and funnel plot bias test were carried out. Results Finally, six English literatures were enrolled. The results of Meta-analysis showed that the combined RR value of Alzheimer's disease in the patients with hearing impairment was 3.00 (95% CI: 1.58-5.70,P=0.0008). Conclusions There is a correlation between hearing impairment and Alzheimer's disease.
