Hearing aids and Cognition (CogniAid) Study

We are recruiting for the CogniAid trial investigating hearing aid fitting strategies and cognition in older New Zealanders.

What's involved?

We are particularly interested in helping older individuals with a hearing loss, who have mild cognitive impairment or who are experiencing mild difficulties in memory and attention.

This research will compare standard hearing aid fitting to a hearing aid fitting modified according to results on of attention and memory tests. These results will directly lead to better hearing services for older New Zealanders.
