Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are English-speaking adults aged 60 and older with diminished or lost sense of smell who have not previously undergone smell training.
✕Probably not a fit
Patients with sensitivity to the scents used in the study or those diagnosed with congenital anosmia may not benefit from this intervention.

What this trial studies
This clinical trial aims to evaluate the effectiveness of ScentCare, a novel olfactory training device, in enhancing olfactory function and overall well-being in older adults experiencing olfactory dysfunction. Participants will be randomly assigned to either use the ScentCare device or solve Sudoku puzzles for three months, with their olfactory abilities assessed before and after the intervention. The study also includes surveys to evaluate quality of life, cognitive function, and compliance with the training regimen. By standardizing olfactory training, the researchers hope to provide a more effective rehabilitation method for those with smell loss.
Why it matters
Potential benefit: If successful, this study could lead to improved olfactory function and quality of life for older adults with smell loss.
How similar studies have gone: Previous studies have shown that olfactory training can be beneficial, but the use of a standardized device like ScentCare is a novel approach.
