What is central hearing loss in the elderly?

Central deafness lesions are located in the brainstem and brain, involving the nucleus of the cochlear nerve and its central conduction pathway, the auditory cortex center leads to central deafness.

Diagnosis

Central deafness results when the lesion is located in the brainstem and cerebrum, and involves the cochlear nucleus and its central conduction pathways, and the auditory cortical centers.

Ear section

(1)Brainstem central deafness: the involvement of the cochlear nerve nucleus produces one-sided deafness, the degree of mild; if the involvement of one side of the cochlear nerve nucleus and the opposite side of the cross-fiber produces bilateral deafness, with part of the sexy sound deafness, common in the bridge, medulla oblongata lesions.

(2) cortical deafness: cortical deafness is difficult to recognize the distance and nature of the sound, sometimes although the general hearing is not impaired, but for the aesthetic ability to reduce the language. As a result of one side of the cochlear nerve nucleus fibers projecting to the auditory cortex bilaterally, one side of the auditory cortex is damaged or one side of the conduction pathway is damaged to produce one or both sides of the hearing loss.
