Research shows that dogs can be specially trained to detect Parkinsonās disease by sniffing skin swabs from affected individuals. Two medical detection dogs, Bumper and Peanut successfully identified PD with accuracy rates of around 80% for true positives and a 98% accruacy for false positives.
Dogs can be trained to smell the volatile compounds associated with Parkinsonās disease well before the appearance of typical neurological symptoms. This povides hope for a much earlier diagnosis that is non-invasive and can give space for medical intervention before serious motor impairments are developed.
Some doctors believe that this could eventually lead to new, technology-based diagnostics inspired by dogās exceptional olfactory abilities, revolutionizing the way Parkinsonās is diagnosed and managed in the future.
With up to 80% accuracy, this offers a promising, non-invasive way to diagnose the disease early. It could also inspire future technology that mimics dogsā powerful sense of smell for medical use.
Now the real question isā¦in the future will this be used to detect Parkinsonās disease through dog ? Or will scientists identify or isolate something from the dog that can detect Parkinsonās and recreate it artificially?
Trained dogs detecting Parkinsonās before symptoms appear and that also with up to 80% accuracy, could forever change early diagnosis forever.
This non-invasive method may even inspire tech-based tools.
These volatile organic compounds can be found in the blood, skin, urine and stool sample of the PD patients. They may use various chromatography techniques to detect these volatile compounds. Various clinical trials are going on in developing biomarkers for PD based on these volatile compounds detection.
