December 13, 2025 updated by: Hospices Civils de Lyon

Clinical Trial on Cognitive, Behavioural, Quality of Life and Medico-economic Benefits of Hearing Aids in Alzheimer Disease Patients Suffering From Presbycusis

This is a 12-months' randomized clinical trial that aims at studying the benefit of bilateral hearing aids in hearing impaired patients suffering from a slight to moderate stage Alzheimer disease.

The benefit of this intervention will be studied in the cognitive, behavioural, quality of life and economic fields.

2groups are involved in this trial: Intervention group: 12 months' treatment with active hearing aids, fitted hearing impairment Control group: 6 months' treatment with placebo hearing aids, followed with 6 months' active hearing aids, fitted hearing impairment
