Spiral drawing test detects signs of Parkinson’s

A test that involves drawing a spiral on a sheet of paper could be used to diagnose early Parkinson’s disease. Australian researchers have trialled software that measures writing speed and pen pressure on the page.

Both are useful for detecting the disease, which causes shaking and muscle rigidity.


The Melbourne team said the test could be used by GPs to screen their patients after middle age and to monitor the effect of treatments. The study, published in Frontiers of Neurology, involved 55 people - 27 had Parkinson’s and 28 did not. Speed of writing and pen pressure while sketching are lower among Parkinson’s patients, particularly those with a severe form of the disease.


In the trial, a tablet computer with special software took measurements during the drawing test and was able to distinguish those with the disease, and how severe it was. Poonam Zham, study researcher from RMIT University, said: “Our aim was to develop an affordable and automated electronic system for early-stage diagnosis of Parkinson’s disease, which could be easily used by a community doctor or nursing staff.”
