Pdf Summary

Multiple studies have shown that hearing loss is the most significant modifiable risk factor for reducing the risk of dementia. A comprehensive audiometric evaluation is necessary to diagnose and manage hearing loss and related difficulties in listening and comprehension. Hearing screenings do not provide information about auditory processing, linguistic ability, comprehension, speech-in-noise ability, or listening skills. Hearing and listening are not synonyms - hearing refers to the ability to detect sound, while listening refers to the ability to comprehend and derive meaning from sound. Normal human hearing is desirable, but human listening abilities are unique and cannot be replicated by non-human animals. There are millions of Americans with hearing difficulty and speech-in-noise problems who do not have hearing loss on traditional audiograms. These individuals may have suprathreshold listening disorders that impact their ability to process sound and comprehend speech. Cognitive screenings are recommended for adults over age 55 and those who report speech-in-noise and hearing difficulties, as there is a strong relationship between cognition and audition. Early diagnosis and intervention for cognitive decline and dementia can potentially alter the trajectory of these conditions. Cognitive screenings should be used to identify individuals who may require further assessment and diagnosis. Comprehensive audiometric evaluations are essential for identifying and managing hearing loss, suprathreshold listening disorders, and other communication-based disorders. Early intervention can lead to improved outcomes and potentially delay the onset and progression of dementia.
