Summary

The goal of this observational study is to learn about the brain imaging changes associated with concussion using a very detailed (7T) MRI scanner. To do this, the investigators will study 7T MRI brain imaging in patients aged 18-40 who present to the Emergency Department within 96 hours of a head injury. Patients will be eligible if they have had a normal CT brain as part of their usual care. The investigators will compare brain imaging from patients who have completely recovered from an episode of concussion to patients who still have significant symptoms at approximately 28 days after a head injury. The study attempts to answer the following questions: 1. Do patients with ongoing symptoms after concussion show greater 7T MRI brain imaging evidence of changes to the blood vessels at approximately 28 days after their injury in comparison to patients who have recovered fully? 2. Do patients with ongoing symptoms after concussion show greater 7T MRI brain imaging evidence of changes in brain signaling pathways at approximately 28 days after their injury, in comparison to patients who have recovered fully?

Detailed description

Evaluation of symptoms will be conducted at presentation in the Emergency Department and at 25 +/- 3 days after head injury. This will be assessed using 2 validated questionnaires: the Neurological Assessment Questionnaire (NAQ) and the Post Concussion Symptom Scale (PCSS). Lifetime incidence of concussion will be assessed at 7T MRI using the a modified version of the Brain Injury Screening Questionnaire (BISQ). Information will also be collected regarding painkiller use, anticoagulation, return to work, and any related further unscheduled care admissions or CT head imaging.
