The journal The Lancet published yesterday the “ACHIEVE” study which assesses the comparative benefits of hearing care or health education (chronic disease prevention sessions) on American seniors. It gives the advantage to auditory rehabilitation to prevent cognitive decline.
This multicenter and randomized study* concerns Americans aged 70 to 84 with uncorrected hearing loss but no apparent cognitive disorders. The participants were randomly divided into two groups (just under 500 subjects in each). The impact of the “interventions” was measured following 3 years of follow-up, by an overall cognitive score established from a battery of neurocognitive tests. Overall, no notable difference was found, at 3 years, between the group having received hearing care and the group having benefited from advice on the prevention of chronic diseases. But the people included in the study had 2 different profiles: some came from a large long-term cohort – focused on the risk of atherosclerosis – the others were healthy volunteers. For the participants of the 1st cohort, on average older and presenting more risk factors for cognitive decline, auditory rehabilitation seems to have significantly outperformed health education in preventing or slowing down cognitive decline.

As a reminder, a study in this field will be launched in France this year, in Cahors.
