University of Southern California scientists find tears can help diagnose Parkinson's disease.

It turned out that people who suffer from this disease have a different amount of a certain protein in their tears than healthy people.. Mark Lew, one of the authors of the work, is confident that tears should now help neurologists identify patients with Parkinson's disease at an earlier stage in the development of the disorder..

He says that this marker can be quite useful in the diagnosis, as well as for the development of therapy for Parkinson's disease, since the disease often begins to develop long before the patient and doctors can detect the first symptoms..

Recall that Parkinson's disease is a progressive disease that destroys the cells in the patient's brain that are responsible for the production of dopamine in the human body, which in turn is responsible for controlling movement.. The first symptoms of the disease: stiffness in movements, tremor, difficulty in balancing and maintaining balance, disturbed night sleep, depressive states and much more.
