	'''Cortical deafness''' is a rare form of [[hearing loss]] that occurs due to damage to the [[primary auditory cortex]] in the [[brain]]. Unlike other forms of hearing impairment, cortical deafness is not caused by damage to the [[ear]] or the [[auditory nerve]], but rather by lesions in the [[cerebral cortex]].

	Cortical deafness results from bilateral damage to the [[primary auditory cortex]], which is located in the [[temporal lobe]] of the brain.

	Individuals with cortical deafness typically present with a complete inability to perceive sound, despite having intact auditory pathways up to the level of the cortex.

'''Cortical deafness''' is a rare form of [[hearing impairment]] resulting from bilateral cortical damage. This condition is characterized by an inability to perceive sounds, despite functioning ears and an intact [[auditory nerve]].

== Causes ==

Cortical deafness is typically caused by bilateral damage to the primary [[auditory cortex]]. This damage can occur due to a variety of factors, including [[stroke]], [[trauma]], [[infection]], or [[neurodegenerative disease]]s.

== Symptoms ==

Individuals with cortical deafness may appear to be completely deaf, as they do not respond to sounds in their environment. However, they may still be able to feel vibrations and perceive changes in air pressure. Some individuals may also experience [[auditory hallucination]]s or [[tinnitus]].

== Diagnosis ==

Diagnosis of cortical deafness is typically made through a combination of [[audiometry]] tests, [[neuroimaging]] studies, and clinical evaluation. Audiometry tests can confirm that the individual's ears and auditory nerve are functioning properly, while neuroimaging studies can identify damage to the auditory cortex.

== Treatment ==

There is currently no cure for cortical deafness. Treatment is focused on managing symptoms and improving quality of life. This may involve the use of [[assistive technology]], such as [[hearing aid]]s or [[cochlear implant]]s, and [[rehabilitation therapy]] to help individuals adapt to their hearing loss.
