Improvment in Cognitive Abilities and Quality of Life After Cochlear Implantation in the Elderly
A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing in both ears, it is bypass the normal hearing process; they have a sound processor that resides on the outside of the skin (and generally worn behind the ear) which contains microphones, electronics, battery, and a coil which transmits a signal to the implant. The implant has a coil to receive signals, electronics, and an array of electrodes which is placed into the cochlea, which stimulate the cochlear nerve.
Hearing loss is a prevalent consequence of aging and poses special challenges for older adults. Particularly when superimposed on other age‐related conditions, presbycusis (age‐related hearing loss) places older adults at risk for social isolation and associated psychological and general health sequelae. The increasing cognitive demand of communication and the diminished sense of social connectedness can contribute to a feeling of poor health that worsens with advancing presbycusis.There is accumulating evidence of a potential role for cochlear implant in older adults with hearing loss .The purpose of this report is to evaluate, the effectiveness of CI (cochlear implant) in older adults presenting sensorineural hearing loss, using as indices audiological data and information from quality of life (QOL) questionnaires.
