What are the causes of Sensorineural hearing loss?

Question

A couple years ago i went and got this test done that checked for nerve damage in my ears. They found nerve damage in my left ear. My mom notice something was wrong when i was a baby. But they didn't know all of this. I have deafness. It is mild to moderate hearing loss, 40 to 50 db loss. db=decibels.


brainstem auditory evoked response (BAER) test - can diagnose hearing ability and can indicate the presence of brain stem tumors and multiple sclerosis. Electrodes are placed on the scalp and earlobes. Auditory stimuli, such as clicking noises and tones, are delivered to one ear.

That is the testing i had done.
I wear a hearing aid for my left ear.

Also i am 21 years old.
I also have mild mental retardation,deafness,communication disorder,adhd,sensory issues.

Answer 1

I have 2 children w/ Sensorineural hearing loss. They both wear hearing aids. It is kind of a misnomer (named wrong) because it isn't acutally a loss, they never had it to begin with. Most likely something they were born with, something in their ears never developed correctly.

Answer 2

Sensorineural hearing loss is due to damage to the pathway for sound impulses from the hair cells of the inner ear to the auditory nerve and the brain. Possible causes include:

age-related hearing loss - the decline in hearing that many people experience as they get older

acoustic trauma (injury caused by loud noise) to the hair cells

viral infections of the inner ear (may be caused by viruses such as mumps or measles)

Ménière's disease (abnormal pressure in the inner ear)

certain drugs, such as aspirin, quinine and some antibiotics, which can affect the hair cells

acoustic neuroma, a benign (non-cancerous) tumour affecting the auditory nerve

viral infections of the auditory nerve (such as mumps and rubella)

infections or inflammation of the brain or brain covering - eg meningitis

multiple sclerosis

a brain tumour

a stroke
