Dogs trained to detect Parkinson’s disease using scent have shown remarkable accuracy in new research. In a double-blind trial, they identified skin swabs from people with Parkinson’s with up to 80% sensitivity and 98% specificity, even when other health conditions were present. The findings offer hope for a simple, non-invasive diagnostic method using biomarkers that appear long before traditional symptoms, potentially allowing earlier treatment and slowed disease progression.
For those who don’t know the early symptoms also lead the severe symptoms by years. If you experience loss of smell and constipation, go to your doctor and get checked.
