Quick Summary

Cortical deafness is a type of hearing impairment caused by damage to the auditory cortex of the brain. This is distinct from conductive hearing loss, which affects the outer or middle ear, and sensorineural hearing loss, which involves the inner ear or auditory nerve.12

Unlike other types of hearing loss, conductive and cortical hearing loss cannot be effectively treated with hearing aids or surgery due to nerve damage that distorts sound. Agnosia, a broader term, refers to the loss of ability to recognize sensory stimuli, which can include auditory agnosia, the inability to comprehend sounds. Cortical deafness specifically impacts the brain's processing of auditory information.13
