Subvert traditional cognition! Scientists have discovered the real cause of "old deafness".

Read: New research has identified new causes of age-related hearing impairment and opened up new therapeutic directions.!---- you may have had this experience: when talking to the elderly at home, they were always unable to hear or interrupt, their voices were deaf, their voices were loud and noisy - that's what people call "old-age deafness.""old age deaf" is one of the most common diseases of the elderly, because they can't hear others or always interrupt, the elderly will be afraid of being ridiculed and become indecisive, over time will have a serious impact on their physical and mental health.For the past 60 years, it has been thought that the main cause of this age-related hearing loss is vascular damage.vascular patterns are cell "batteries" that power the electromechanical signal conversion of hair cells.and a recent new study of human ear tissue has opened up new therapeutic avenues by upsetting this traditional perception and identifying new causes of age-related hearing impairment. On July 20,, researchers at the Eaton-Peabody Laboratory at the Massachusetts Eye and Ear Hospital, affiliated with Harvard Medical School, published their latest findings in Journalof Neuroscience: Age-related hearing impairment is caused by damage to hair cells, the sensory cells of the inner ear that convert sound vibrations into electrical signals and pass them to the brain through the auditory nerve.newly discovered VS Old Idea researchers collected 120 inner ears through autopsies and used multivariate statistical regression analysis to compare the survival rates of hair cells, nerve fibers, and vascular lines with the patient's hearing map, and found that the extent and location of hair cell death could predict the severity and manner of hearing damage, while vascular damage was not.histopathology analysis of four normal aging cases, human "older deafness" VS animal models by measuring hearing in people with hearing impairment and model animals, found that the hair cell degeneration of aging people was much more severe than in "older deaf" model animals.this is because the experimental animals are old in a controlled sound environment and are not disturbed by the constant medium- and high-intensity noise around them.it can be seen that old age deafness can be avoided, this high-frequency hearing impairment is mainly due to the cumulative damage caused by environmental noise., the authors say, if we take care to protect our ears in a long-term noisy environment, or avoid being in this environment altogether, we are likely to maintain good hearing levels in old age.animals (A1, 2, 3) and human (B1, 2, 3) age-related hearing impairment histology and hearing measurement study has upended our previous understanding of the main causes of age-related hearing impairment, meaning that millions of "older deaf" patients will benefit from hair cell regeneration therapy, which is the focus of ongoing research worldwide.References: s1 Age-hearing sion sied by damage to sensory sensory cells, not the sicellular battery that powers them.
