Mild traumatic brain injury (MTBI) is a common condition, afflicting as man
y as 1.5 million Americans yearly. Most individuals sustain MTBI as a resul
t of motor vehicle collisions, but it may also occur as a result of falls,
physical assault or sporting accidents. Problems related to MTBI include va
rious pain syndromes, cognitive impairments, disorders of affect, cranial n
erve dysfunction, and vertigo, arising from injury to the brain, head, or c
ervical spine. Symptoms are usually transient, although a small percentage
of afflicted individuals develop long-lasting problems, often preventing th
em from leading productive lives. Recognition of these problems as arising
from MTBI is difficult due to the frequent lack of abnormal findings on dia
gnostic tests and failure to identify a history of head trauma. The America
n Congress of Rehabilitation Medicine has defined MTBI, an important first
step in identifying individuals who need treatment. Diagnosis is usually ma
de by directed questions regarding trauma history and careful procurement a
nd interpretation of appropriate tests. Once a diagnosis is made, proper ca
re can be prescribed in order to lead patients toward more productive lives
