The article discusses the relationship between hearing loss and cognitive decline in older adults, highlighting the need for interdisciplinary collaboration to better understand this link. It emphasizes that age-related hearing loss (ARHL) is often perceived as an inconsequential part of aging but may actually accelerate cognitive decline. The authors, including experts from various fields, organized a workshop to raise awareness and stimulate research on this topic. Key points include the high prevalence of hearing loss in both the US and Europe, particularly among older adults, and the significant economic and social costs associated with untreated hearing loss. The article also projects that the global prevalence of dementia will increase substantially by 2050, underscoring the importance of addressing hearing loss to potentially delay cognitive decline and dementia.The article discusses the relationship between hearing loss and cognitive decline in older adults, highlighting the need for interdisciplinary collaboration to better understand this link.
