Can you draw a spiral? It could determine your risk of Parkinson’s: App can spot disease hallmarks by measuring speed and pressure

The way you draw a spiral could reveal whether you will get Parkinson’s disease.

Researchers at Rmit University in Melbourne, Australia, asked volunteers to draw a spiral on a sheet of paper.

By analyzing their speed and how hard they pressed the pen on the paper, the team could tell which volunteers had Parkinson’s disease.

They could also tell how severe their diagnosis was. 

The current study builds on previous research which found that Parkinson’s patients tend to move their pen more slowly when sketching, and use less pressure on the page.
