Summary

This prospective longitudinal cohort study will enroll adults aged 50 years and older to characterize olfactory dysfunction in aging. Participants will undergo comprehensive olfactory testing, cognitive assessment, biomarker collection, and imaging to identify clinically relevant phenotypes based on anatomic site of dysfunction. The study will also evaluate the impact of olfactory dysfunction on quality of life and identify baseline factors associated with changes in olfactory function over time.
