Dogs' Noses Detect Parkinson’s Disease

Two dogs were trained to identify Parkinson's disease in sebum samples.

Dogs achieved sensitivity of 70% and 80%, specificity of 90% and 98%.

The study involved 205 initial samples and 100 new samples in a double-blind trial.

Significant discrimination between PD and control groups was found (p<0.0001).

Findings support prior research on canine olfactory abilities in detecting PD.

Future research may explore early detection capabilities.

Dogs are not proposed as diagnostic instruments.
