Researchers report that age-related hearing loss is associated with a decrease of cholesterol in the inner ear.
Experiments published August 24 in the open access journal PLOS Biology show that phytosterols supplements were able to act in place of the lost cholesterol and prevent sensory dysfunction in mice.
Sensory cells in the inner ear called outer hair cells (OHCs) amplify sounds by changing their length. As we age, these cells lose their ability to stretch in response to sound, preventing sound amplification and leading to age-related hearing loss...
