Cortical deafness

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 diseases.

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 hallucinations 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 aids or cochlear implants, and rehabilitation therapy to help individuals adapt to their hearing loss.
