A study at the UK Bristol Veterinary School reveals that trained dogs can accurately identify drug-naïve Parkinson’s disease (PD) in sebum samples, achieving up to 80% sensitivity and 98% specificity. Researchers trained two dogs using 205 samples from PD patients and controls over 38 to 53 weeks. The study utilized a double-blind design involving 100 new samples and demonstrated significant discrimination between PD and control samples. While the findings highlight the potential for using dogs in biomarker evaluation, the researchers do not propose them as diagnostic tools.
