Accumulation of blood within the brain can cause further damage by exerting pressure within the brain: serious health problem. In the united states alone, approximately 1. 4 million people visit an emergency room for tbi, 270,000 people are hospitalized, and. Almost a third of deaths caused by injury involve tbi.
