Autoimmune inner ear disease (AIED) was first defined by Dr. Brian McCabe in a landmark paper describing an autoimmune loss of hearing. [2] The disease results in progressive sensorineural hearing loss (SNHL) that acts bilaterally and asymmetrically, and sometimes affects an individual's vestibular system.
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments.
There is no treatment to correct an enlarged vestibular aqueduct. Any hearing loss will need management with amplification and support in education and at work. If the hearing loss becomes severe to profound, cochlear implants can be of significant value. Vestibular disturbance is usually short-lived and associated with head trauma, but ...
Based on clinical testing of subjects with auditory neuropathy, the disruption in the stream of sound information has been localized to one or more of three probable locations: the inner hair cells of the cochlea, the synapse between the inner hair cells and the auditory nerve, or a lesion of the ascending auditory nerve itself.
The symptoms of cochlear hydrops fluctuate, and the condition may stabilize or go away on its own after several years. However, because the organ of Corti undergoes stress during the hydrops episodes, long-term hearing loss, tinnitus, or hyperacusis is possible. It is considered by some that cochlear hydrops is an early form of Meniere's disease.
The internal implant sends the signals to the electrode array. The design of the electrode array is the key difference between a cochlear implant and an ABI. Whereas the electrode array for a CI is wire-shaped and is inserted into the cochlea, the electrode array of an ABI is paddle-shaped and is placed on the cochlear nucleus of the brainstem. [3]
A totally implantable cochlear implant (TICI) is a new type of cochlear implant and is currently in development.Unlike a conventional cochlear implant, which has both an internal component (the implant) and an external component (the audio processor), all the components of the TICI - including the microphone and battery - are implanted under the skin.

Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
