Dogs Can Detect Parkinson's Disease with Nearly 90% Accuracy

Scientists have taught dogs to recognize Parkinson's disease by smell with an accuracy of almost 90%. This may be due to special substances emitted by human skin. Dogs can potentially be used to screen samples from individuals with early symptoms of Parkinson's disease to determine who will need further analysis and subsequent treatment. In the future, this could become an effective and affordable method of diagnosing the illness.
