Loss of smell may predict dementia a decade before diagnosis

A 12-year study found that olfactory dysfunction is a reliable early marker of dementia risk, potentially enabling earlier interventions. For healthcare systems and pharmaceutical companies, this finding offers a simple, non-invasive screening tool that could identify at-risk populations before cognitive decline becomes severe—opening new opportunities in preventive care and drug development.
