背景资料：老年痴呆症患者的听力功能受损，并且已知听力差会夸大认知缺陷的影响。目的：本研究的目的是评估通过向患有轻度听力损失的老年痴呆症患者提供助听器来增加听觉敏锐度的效果。方法：根据标准临床实践筛选患者的听力损伤并装配助听器。认知和精神症状，日常生活活动和照顾者的负担的措施超过6个月。保留助听器日记以记录受试者对助听器的可接受性。结果：超过10%的符合条件的受试者因去除耳垢而恢复听力而被排除。受试者在研究期间表现出认知功能下降，行为或精神症状没有变化。42%的受试者在独立评定的变化指标上表现出改善。助听器是很好的接受。照顾者和主题报告的整体减少残疾听力implementation.Conclusions：所有听力障碍患者需要彻底的检查。老年痴呆症的存在不应排除对助听器的评估，因为它们具有良好的耐受性，并可减少听力障碍引起的残疾。助听器不能改善认知功能或减少行为或精神症状。有证据表明，患者在全球变化措施方面有所改善。
Background: audiological function is impaired in people with dementia and poor hearing is known to exaggerate the effects of cognitive deficits.Objective: the objective of this study was to assess the effects of increasing auditory acuity by providing hearing aids to subjects with dementia who have mild hearing loss.Method: subjects were screened for hearing impairment and fitted with a hearing aid according to standard clinical practice. Measures of cognition and psychiatric symptoms, activities of daily living, and burden on carers were made over 6 months. Hearing aid diaries were kept to record the acceptability of the hearing aids to the subjects.Results: more than 10% of eligible subjects were excluded as removal of wax restored hearing. Subjects showed a decline in cognitive function, no change in behavioural or psychiatric symptoms over the study period. Forty-two percent of subjects showed an improvement on an independently rated measure of change. The hearing aids were well accepted. Both carers and subjects reported overall reduction in disability from hearing impairment.Conclusions: all patients with hearing impairment require thorough examination. The presence of dementia should not preclude assessment for a hearing aid as they are well tolerated and reduce disability caused by hearing impairment. Hearing aids do not improve cognitive function or reduce behavioural or psychiatric symptoms. There is evidence that patients improved on global measures of change.
