Cortical Deafness

Cortical deafness is a rare form of sensorineural hearing loss caused by damage to the primary auditory cortex of the brain.

Pronunciation

Cortical deafness is pronounced as kor-ti-kal deaf-ness.

Etymology

The term "cortical" is derived from the Latin word "cortex", which means "bark" or "rind". In medical terminology, it refers to the outer layer of an organ or other structure. "Deafness" comes from the Old English word "deaf", which means lacking the power of hearing.

Definition

Cortical deafness is a condition where patients are unable to hear sounds, despite having normal functioning of the peripheral auditory system, including the inner ear and auditory nerve. This is due to damage to the auditory areas of the cerebral cortex, specifically the primary auditory cortex.

Symptoms

Symptoms of cortical deafness can include complete inability to hear sounds, difficulty understanding spoken language (auditory agnosia), and difficulty localizing sounds. Some patients may also experience tinnitus, a ringing or buzzing in the ears.

Causes

Cortical deafness can be caused by a variety of conditions that damage the primary auditory cortex, such as stroke, traumatic brain injury, brain tumors, or neurodegenerative diseases like Alzheimer's disease.

Treatment

Treatment for cortical deafness is typically focused on managing symptoms and improving quality of life. This can include speech therapy, auditory rehabilitation, and the use of assistive devices like hearing aids.
