Researchers from Central Health, Memorial University of Newfoundland (MUN) and McMaster University (Mac) are working with Audiology experts in Grand Falls-Windsor (Suite Q) to explore potential genetic contribution to the established association between cognitive and auditory decline in older Canadians. 


 Potential outcomes could include differentiated diagnostics based on genomics and targeted treatment pathways for seniors at risk of developing a Neurocognitive Disorder.
