MicroRNAs (miRNAs) may serve as biomarkers of concussion with prolonged symptoms, according to results of a prospective cohort study published online November 20 in JAMA Pediatrics.

More than 80% of concussions follow mild traumatic brain injuries (mTBIs). For one-third of children, symptoms of concussion persist beyond 2 weeks. A tool to predict children at elevated risk for prolonged concussion symptoms (PCS), other than questionnaires to identify clinical risk scores, would be valuable in referring appropriate patients to specialists.


Brain Imaging Identifies CTE in a Living Person

New research appears to confirm that positron emission tomography (PET) imaging using the [F-18] FDDNP tracer can identify the distinctive brain tau pathology of chronic traumatic encephalopathy (CTE) in a living person.

The neuropathological findings during a brain autopsy of a retired National Football League (NFL) player confirmed the “fingerprint” signature of CTE uncovered by a previous in vivo [F-18] FDDNP-PET scan
