In this new study performed in mice, rapamycin supplementation lessened, but does not reverse, age-related hearing loss in mice even if the treatment starts later in middle age. The researchers of this study had previously found that age-related hearing loss was minimized in mice who had been receiving rapamycin since they were young. In this new study, the researchers wanted to see if these results could be replicated with treatments started later in middle age. The researchers were successful and found that rapamycin treatments given to mice that were 14 months old — which is equivalent to approximately 50 years in humans — prevented them from developing further hearing loss.
