What is it about?

The influence of a reduced dietary intake of folic acid on hearing loss is explored. This vitamin deficit accelerates the development of profound hearing loss that are due to severe alterations in cochlear histology. The reduced folic acid intake also alters cochlear homocysteine metabolism and induces oxidative stress.
