There is an opinion that dogs can identify Parkinson's disease by smell...
Yes, it is indeed true. American scientists reported this by publishing the results of their research on the BioRxiv platform, which serves as an electronic archive for scientific articles in biology.
According to one of the authors of the study, Lisa Holt, her team managed to train domestic dogs to recognize Parkinson's disease by smell with an accuracy of nearly 90%. The experiment involved 23 dogs of various breeds, ages, and sexes. They underwent training consisting of 200 sessions over several years. The training used chemicals released by human skin, which are not harmful to the animals.
In the future, it is expected that dogs will be used to monitor the condition of people and for early detection of the disease. However, Lisa Holt notes that there are still many uncertainties in this area, and research needs to continue.
