Abstract(s)

Cortical deafness is an extremely rare clinical manifestation that originates mainly from bilateral cortical lesions in the primary auditory cortex. Its main clinical manifestation is the bilateral sudden loss of hearing. Diagnosis is difficulty due to its rarity and similarity with other language and communication disorders, such as Wernicke's aphasia, auditory agnosia or verbal deafness. Herein, we present a case report of a young woman with a sudden bilateral loss of auditory comprehension. Initially, a psychiatric nature of the disorder was considered, but the persistence of the symptoms, lead to the diagnosis of cortical deafness secondary to bilateral ischemic lesions in both temporal lobes. Progressive improvement occurred and three months after the initial manifestations she manifested pure verbal deafness. Cortical deafness usually has a poor functional prognosis, with limited therapeutic options. Rehabilitation and speech therapy is recommended to improve the chance of patients achieving communication skills.
