Levels Of Protein EGF In Blood May Help Predict Risk Of Cognitive Decline In People With Parkinson’s Disease, Study Finds

Parkinson’s News Today (2/13, Wexler) says, “Levels of the protein epidermal growth factor, or EGF, in blood may help predict the risk of cognitive decline in people with Parkinson’s disease, a study reports.” Researchers found “that about half of patients with EGF blood levels below 49.56 picograms per milliliter would later develop cognitive impairment based on [Montreal Cognitive Assessment] scores, whereas more than 90% of patients with EGF levels above this cutoff wouldn’t later see cognitive impairment.” The findings were published in Neurological Sciences.
