A 61-year-old man sustained a mild traumatic brain injury (mTBI) following a pedestrian versus vehicle traffic accident. Post injury, he began to experience symptoms including light-headedness, spatial disorientation, nausea, fatigue and prominent dizziness brought on by postural change, physical activity or eye movements. Symptoms of dizziness persisted for over 5 years, despite numerous extensive and rigorous vestibular and vision therapy regimens.

Objective To determine if 1H NMR spectroscopy of urine and a quantitative metabolomics approach can aid diagnostic and prognostic outcomes in patients who have suffered acute sport concussion. Design Pre-concussion urine samples were collected from WinSport athletes at the beginning of the sport season. Any athlete who experienced a head injury reported to a brain injury clinic to be tested within 72 hours of head injury.
