Parkinson’s severity assessed through drawing


(Frontiers) Researchers in Australia asked volunteers to draw a spiral on a sheet of paper. By analyzing how long it took them to draw the spiral and how hard they pressed on the paper with the pen, the team could not only tell which volunteers had Parkinson’s disease, they could also tell how severe it was. Doctors could use the automated system in their surgery to easily diagnose the disease or keep track of the progress of existing patients.
