Many types of accidents, including car accidents and motorcycle accidents, can result in traumatic brain injury (TBI). A traumatic brain injury may occur if the head hits or its hit by a hard object, or if a sharp object pierces the brain.
The phrase “traumatic brain injury” covers nearly all injuries to the brain, from mild to severe, according to the National Institute of Neurological Disorders and Stroke. The symptoms of a TBI include headache, dizziness, confusion, blurred vision, and nausea or vomiting. The injury may also cause a person to lose consciousness.
Mild traumatic brain injuries often heal completely on their own, under the supervision of a physician. More severe injuries may require intensive therapy and rehabilitation before the patient recovers. In the most severe cases, a TBI can permanently change a person’s body and brain functions, causing such disabilities as inability to speak, loss of motor control, or paralysis.
