Developing 'game-changing' test to diagnose Parkinson's ANI | Updated: Mar 14, 2021 23:43 IST Washington [US], March 14 (ANI): A team of scientists at The University of Manchester discovered in recent research that it is possible to identify Parkinson's based on compounds found on the surface of the skin. The findings offer hope that a pioneering new test could be developed to diagnose the degenerative condition through a simple and painless skin swab. Scientists at The University of Manchester have developed a technique that works by analysing compounds found in sebum - the oily substance that coats and protects the skin - and identifying changes in people with Parkinson's Disease. Sebum is rich in lipid-like molecules and is one of the lesser-studied biological fluids in the diagnosis of the condition. People with Parkinson's may produce more sebum than normal - a condition known as seborrhoea.
