A blood test that can predict cognitive impairment in Parkinson’s disease sufferers has been developed by researchers at the University of Pennsylvania School of Medicine in the US.

The test measures epidermal growth factor (EGF), a blood plasma protein involved in the regulation cell growth, proliferation and differentiation.

Researchers found that Parkinson’s disease patients with low EGF levels and normal cognition were at high risk of developing serious cognitive impairments during the 21-month median follow-up period.

They added that the test could also be used to select patients for clinical trials of Parkinson’s drugs.
