Concussion causes
Overview
The leading causes of MTBI in adults are falls and vehicle accidents, and other causes include sports injuries, assaults, industrial and work-related injuries, and injuries that occur in the home.[1] Among children aged 5 to 14, sports and bicycle accidents cause the greatest number of concussions.[2] Soldiers are at elevated risk for concussion from causes such as bomb blasts, with as many as 15% of U.S. infantry soldiers who return from the Iraq War meeting the criteria for MTBI.[3] The relative contribution of causes of mild head injury differs by region, gender, and age.[4] For example, in Scotland and Sweden, falls account for the greatest percentage of MHIs, while in the U.S. and Australia, transportation is the largest cause.[4]
