简要总结
This study utilizes multimodal brain imaging to obtain quantitative biomarkers of brain injury and to improve understanding of the biological basis of brain pathology in adolescents with concussion. Adolescents with a concussion will undergo neuroimaging and neuropsychology assessments acutely and four months after injury.
详细描述
Concussion is a highly prevalent condition in adolescence, but it remains a clinical diagnosis that largely relies on subjective patient report with no reliable objective biomarkers for diagnosis. Traditional clinical brain imaging has not been found useful for concussion as the pathology is generally not visible on conventional acute MRI or CT. The proposed study addresses this gap in concussion diagnosis and management by examining the sensitivity of magnetoencephalography (MEG) for identifying areas of brain injury through detection of abnormal neural activity (slowing) in adolescents with concussion compared to healthy controls. Adolescents with a concussion will complete neuroimaging (MEG and MRI) and neuropsychology assessments at two time points within ten days and then again 4 months post-injury. Healthy controls will complete neuroimaging and neuropsychology assessments at a single time point.

结局指标
主要结局
Difference in MEG Whole-Brain Slow-Wave Sensitivity between Controls and Concussion Patients
时间窗: Up to 2 months
Whole-brain, resting-state slow-wave maps of whole brain activity will be obtained from the MEG imaging in both adolescents with a concussion and healthy controls. Control images will be analyzed to determine a whole brain z-score value that includes typically developing controls below the 95th percentile, the z-score threshold for this group). Z-score images for the adolescents with concussion will be obtained and the number of adolescents with concussion above this z-score threshold will be determined, and compared to the healthy controls. The sensitivity and specificity of this method determined.
