Audiologia do envelhecimento: revisão da literatura e perspectivas atuais

Abstract: Aim: to review the literature on aging-related hearing loss and its current impacts. Literature review: In studies carried out in Brazil, presbycusis has been blamed for being the most frequent cause of hearing loss in the elderly, causing verbal communication impairment. International studies also show the high prevalence of hearing loss in the elderly. Discussion: According to recent investigations, as the number of elderly people increase, the prevalence of presbycusis interfering in the life quality of thi… Show more

“…In addition to liminar tonal audiometry, the diagnosis may be complemented by speech audiometry, which measures a person's ability to discriminate and detect speech sounds, classifying an individual's loss of the ability to communicate as a result of his/her hearing loss. However, the gold-standard for diagnosing hearing loss requires high-cost equipment, expert professionals and a suitable environment 12 , all of which make it difficult to implement in primary care, especially far from the larger urban centers. For this reason, presbycusis is under-diagnosed in the thousands of elderly seen by the primary care system, resulting in the consequences of hearing loss such as social isolation, lack of understanding, depression and cognitive decline, often avoidable had the loss been diagnosed in a timely way, and if the patients received rehabilitation 5 .…”

“…The peripheral system, responsible for sensing different sound stimuli, is composed of the outer, middle and inner ear and the auditory nerve. The central auditory system, responsible for decoding the received message and concomitant recoding, is closely linked to the processing of language and other cognitive and emotional functions (6) . This system involves the auditory pathways of the brainstem and cortical areas.…”

“…3 A presbiacusia, apontada como causa mais frequente de perda auditiva em idosos, aparece em função do processo de envelhecimento e atinge a função periférica do sistema auditivo, especialmente a cóclea e o nervo auditivo. 4,5 A degeneração da orelha interna influencia negativamente na análise espectral dos estímulos auditivos recebidos. Essa recepção distorcida irá prejudicar o sinal que é emitido pelo tronco cerebral.…”

“…6 Por esse motivo, o sujeito apresenta dificuldades de compreensão durante a comunicação verbal, principalmente em ambientes ruidosos; incomoda-se com sons muito intensos; apresenta zumbido e dificuldade de perceber sons mais agudos, o que afeta, predominantemente, a compreensão dos sons da fala. 4,5 A deficiência auditiva também pode aparecer em função de outros fatores como a exposição a ruídos intensos, uso indiscriminado de medicamentos e doenças como diabetes, hipertensão, caxumba, entre outros. 7 Um indivíduo com perda auditiva pode sofrer graves implicações psicossociais, tais como isolamento e segregação, fazendo com que passe a evitar situações de comunicação.…”
