Ménière's disease the inner ear. The American Academy of Otolaryngology–Head and Neck Surgery Committee on Hearing and Equilibrium (AAO HNS CHE) set criteria for diagnosing Ménière's, as well as defining two sub-categories of Ménière's: cochlear (without vertigo) and vestibular (without deafness). In 1972, the Academy defined criteria for diagnosing Ménière's disease as: In 1985, this list changed to alter wording, such as changing "deafness" to "hearing loss associated with tinnitus, characteristically of low frequencies" and requiring more than one attack of vertigo to diagnose. Finally in 1995, the list was again altered to allow for degrees of the disease: In 2015, the
Stereocilia (inner ear) can cause permanent damage to inner ear stereocilia. New research has shown that the damage can possibly be reversed if we can repair or recreate some of the proteins in the stereocilia. In this study, scientists used zebrafish to examine the motion of proteins within live ear cells using a confocal microscope. This has shown that proteins in stereocilia move quickly, indicating that the movement of the proteins within the hair cells may be a very important factor to maintaining the integrity of the hair bundles in the inner ear. Further research found myosin and actin, two proteins that are
