Blunt Head Trauma (Archived)

Excerpt

Traumatic Brain Injury (TBI) is a significant cause of morbidity and mortality in the United States, with an annual occurrence of more than 1.5 million. Patients with moderate and severe TBI comprise about 20% of TBI, and those with moderate TBI have a mortality of about 15% while those with severe TBI have associated mortality approaching 40%. The majority (approximately 80%) of patients with TBI have mild TBI which is associated with a less than 0.5% mortality, but about 25% experience extended post-concussive symptoms including a headache, dizziness, difficulty concentrating, and depression.
