Hearing loss and cognitive health strongly correlate

Recent studies provide important new insights on the relationship between hearing health and cognitive health, and the great potential of hearing intervention to slow down the decline of thinking and memory.¹² According to the ACHIEVE study¹ by John Hopkins University, wearing hearing aids can slow down the loss of thinking and memory abilities by 48% over 3 years in older adults at increased risk for cognitive decline. The ENHANCE study² by Prof. Julia Sarant of the University of Melbourne found that people in the hearing aid intervention group maintained their cognitive abilities over three years, while those without hearing intervention showed a decline in cognition over the same period.
