Plasma Tumor Necrosis Factor Alpha Is a Predictor of Persisting Symptoms Post-Concussion in Children

Abstract

Mild traumatic brain injury (mTBI)-associated blood proteomics have become an emerging focus in the past decade, with the U.S. Food and Drug Administration recently approving the use of a blood test to determine the necessity of a computed tomography scan after adult mTBI. We now also know that the blood proteome of children is different from that of adults, and new evidence suggests that children may take longer to recover from an mTBI. Despite this, comparatively fewer studies have analyzed changes in blood protein expression after pediatric mTBI. Concussions, an mTBI subset, often go underreported, despite the potential for post-concussive symptoms to last more than one month in up to 30%..
