Recently, many studies have reported that sensorineural hearing impairment related to neurological disorders may be caused by diabetes mellitus. However, to date, only a small number of studies have investigated the treatment of sensorineural hearing impairment. In the present study, the effects of chlorogenic acid on diabetic auditory pathway impairment were evaluated by neuro-electrical physiological measurements and morphological investigations. We have shown that CA efficiently prevents the progression of auditory pathway dysfunction caused by DM using auditory brainstem responses and auditory middle latency responses in mice. Additionally, using transient-evoked otoacoustic emissions measurement and scanning electron microscope observation of hair cells in DM mice, we found that CA may aid in the recovery from outer hair cell and otic hair cell damage. In conclusion, CA has beneficial effects for the management of diabetic sensorineural auditory dysfunction.
