Concussions and TBI After a Crash: What You Need to Know

By Patrick Kelleher · November 10, 2025 · 7 min read

Brain injuries are one of the most undervalued categories of personal injury claim — partly because the symptoms are real but invisible, and partly because insurers know how easy it is to dismiss them.

First, a CT scan in the ER is not designed to diagnose a concussion. It looks for bleeds and skull fractures. Many traumatic brain injuries — including concussions and diffuse axonal injuries — do not show on CT. A normal CT does not mean a normal brain.

Second, you do not need to lose consciousness to suffer a TBI. Many concussions occur with no loss of consciousness at all.

Third, the symptoms are wide-ranging: headaches, dizziness, brain fog, memory issues, light sensitivity, sleep changes, irritability, depression, executive function problems. They can persist for weeks, months, or longer.

Fourth, documentation matters more than in almost any other case. Symptom journals, family observations, neuropsych testing, and follow-up with the right specialists turn a 'soft' claim into a clear, evidenced one.

If you've been in a crash and something feels different — your memory, your mood, your ability to focus — get it documented. Tell your doctor. See a specialist. The earlier those records exist, the harder it is for an insurer to claim 'it must be from something else.'
