Critical Review:

چکیده
This review examined the published evidence for the existence of a relationship between folate and/or vitamin B12 status and age-related hearing loss, otherwise known as presbycusis. Based on vascular research, it was hypothesized that a decline in folate or vitamin B12 levels could detrimentally affect the highly-vascularized cochlea, especially the stria vascularis, thus resulting in increased hearing threshold levels. Some of the studies examined herein used a correlational design and non-parametric statistical analysis and others used randomized controlled clinical trials with t-testing or ANCOVA—all with human subjects. The results were mixed, with some supporting a relationship and others not.
