Question: 1 / 445

What does Central Nervous System hearing loss refer to?

Loss of hearing that originates in the outer ear

Loss occurring between the inner ear and the brain

Central Nervous System hearing loss specifically pertains to the type of hearing impairment that occurs due to issues in the pathways that carry sound signals from the inner ear to the brain. This condition does not originate from problems in the outer ear, such as those affecting hearing from sound entering the ear, nor is it related to obstruction, like earwax buildup. Moreover, it is distinct from temporary hearing loss, which usually resolves relatively quickly when the underlying cause is addressed.

When hearing loss arises from the central nervous system, it typically involves damage to the auditory pathways or the brain itself. This can result from various factors, such as neurological disorders, trauma, or tumors affecting areas of the brain responsible for processing sound. Understanding this distinction is critical for diagnosing and treating hearing impairments effectively.
