Traumatic Brain Injury

A traumatic brain injury is a disruption of normal brain function caused by an external force, such as a blow, jolt, rapid movement, or penetration. Severity ranges from mild to severe. Effects can involve memory, attention, mood, sleep, balance, speech, movement, or independence. Symptoms and imaging findings vary. A legal claim may require medical, neuropsychological, vocational, and functional evidence to explain diagnosis, causation, prognosis, and daily impact.
