Investigating the impact of hearing aids on cognitive decline in older adults

Early Age-Related Hearing Loss Investigation (EARHLI): A Randomized Controlled Trial to Assess the Mechanisms Linking Early Age-Related Hearing Loss and Alzheimer's Disease and Related Dementias

Not applicable Interventional Columbia University · NCT06174038

This study is testing if using hearing aids can help older adults with early hearing loss and mild memory problems think better and stay socially active compared to those who only get health education.

What this trial studies

The Early Age-Related Hearing Loss Investigation (EARHLI) is a randomized controlled trial that aims to assess the effects of a hearing intervention, including hearing aids, compared to a health education program in late middle-aged adults with early-stage age-related hearing loss and mild cognitive impairment. Participants aged 55-75 will be enrolled and followed for one year, with assessments of cognition, social engagement, and brain connectivity conducted at the start, 6 months, and 12 months. The study will involve approximately 150 participants, with half receiving hearing aids at the beginning and the other half at the end of the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 55-75 with mild to moderate age-related hearing loss and amnestic mild cognitive impairment.

Not a fit: Patients with congenital hearing loss or those whose hearing loss began before middle age may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved cognitive function and quality of life for older adults at risk for Alzheimer's Disease.

How similar studies have performed: Other studies have shown promising results in the relationship between hearing interventions and cognitive outcomes, suggesting potential success for this approach.
