早期聽覺耳蝸與腦幹功能指標比較

// Comparing metrics of cochlear and auditory brainstem function in early-aged ears

本研究針對18至49歲聽力正常成年人，探討早期老化對耳蝸和聽覺腦幹功能的影響｜結果顯示耳蝸發射（DPOAE）和聽覺腦幹反應波I（ABR）幅度皆隨年齡下降，且ABR下降幅度較大，但DPOAE增長無法預測ABR幅度｜研究指出早期耳蝸及神經功能隱性衰退，且兩者測量指標提供不同資訊，有助於臨床診斷年齡相關性聽力損失。

// This study examined how early aging affects cochlear and auditory brainstem function using distortion product otoacoustic emissions (DPOAE) and auditory brainstem response (ABR) wave I amplitude in adults aged 18-49 with normal hearing. Both DPOAE levels and ABR wave I amplitude decreased with age, but declines in ABR were sometimes greater and DPOAE growth did not predict ABR amplitude. Findings suggest early subclinical cochlear and neural decline, with individual differences pointing to cochlear deafferentation. DPOAE and ABR measures provide distinct information that could aid clinical diagnosis of age-related hearing loss.
