Short answer
A traumatic brain injury affects how the brain works and can result from a bump, blow, jolt, or penetrating injury. Symptoms and severity vary, and medical professionals are responsible for diagnosis and treatment. In a personal injury claim, medical records and evidence of changes in work, school, relationships, or daily functioning may become important.
Traumatic brain injuries range from mild injuries such as concussion to more severe brain injuries. Loss of consciousness is not required for every TBI, and some symptoms may not become apparent immediately. Medical evaluation, follow-up care, and accurate symptom documentation are important. See the Concussion guide for additional information.
TBI Symptoms and Severity
Traumatic brain injuries are commonly described as mild, moderate, or severe, but the effects vary significantly from person to person. Concussion is a form of mild TBI. Recovery depends on the injury and the individual, and persistent symptoms should be evaluated by the treating healthcare professionals. See the NINDS TBI page and the Concussion guide.
How a claim may use these facts
A claim still has to prove negligence and that the crash or fall caused the injury. Pre-existing conditions can complicate that proof. See evidence and pain and suffering.
