ALS is the most common form of the motor neuron diseases. [8] ALS often presents in its early stages with gradual muscle stiffness, twitches, weakness, and wasting. [3] Motor neuron loss typically continues until the abilities to eat, speak, move, and, lastly, breathe are all lost. [3]
Excessive vibrations that occur in the inner ear can result in structural damage that will affect hearing. These vibrations result in an increase in the metabolic demands of the auditory system. During exposure to sound, metabolic energy is needed to maintain the relevant electrochemical gradients used in the transduction of sounds.
Stop smoking, which can interfere with circulation and affect hearing. Exercise regularly to prevent health problems, like diabetes or high blood pressure, which can affect hearing.
Cogan's syndrome commonly presents with hearing loss. Multiple sclerosis can affect hearing as well. Multiple sclerosis is an autoimmune disease where the immune system attacks the myelin sheath, a covering that protects the nerves. If the auditory nerve becomes damaged, the affected person will become completely deaf in one or both ears.
Researchers identified a new biomarker for predicting the clinical outcome of patients with ALS, Amyotrophic Lateral Sclerosis, through brain imaging. Researchers Say This Test Can Predict ALS ...
Hearing is lost gradually as the hair cells in the Corti stiffen and die. [10] Changes in the inner ear, middle ear, and complex changes along the nerve pathways from the ear to the brain can also affect hearing. Long-term exposure to noise and some medical conditions can also play a role.

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.
