Concussion After a Car Accident: Symptoms, Care and Claims
Concussions can happen without a head impact and symptoms may be delayed. Learn the warning signs, when to seek urgent care and how to document a concussion.
A concussion is a mild traumatic brain injury caused by a blow to the head or by the head and body being shaken hard. In a car crash it can happen even if you never hit your head, because the brain can move inside the skull when your body is jolted.
Common symptoms
- Headache or a feeling of pressure in the head
- Dizziness, balance problems or nausea
- Confusion, feeling foggy or slowed down
- Memory problems about the crash or after it
- Sensitivity to light or noise
- Trouble concentrating, sleeping or feeling unusually irritable
Symptoms can be delayed
Some symptoms appear hours or days after the crash. If you notice new symptoms after an accident, tell a doctor and mention the crash.
Seek emergency care right away if you have
- Loss of consciousness, even briefly
- A headache that keeps getting worse
- Repeated vomiting
- Seizures, weakness, numbness or slurred speech
- Unusual drowsiness or you cannot be woken
- Increasing confusion or agitation
Why documentation matters for a claim
Concussion symptoms are often invisible on routine scans, so records carry extra weight. Helpful documentation includes:
- Medical visit notes, referrals and follow-up care
- A daily symptom journal (headaches, sleep, concentration, missed work)
- Employer notes about missed or modified work
- Statements from family or coworkers who noticed changes
What affects the value of a concussion claim
There is no standard amount. Insurers and courts look at the severity and length of symptoms, treatment needed, effect on work and daily life, and the evidence connecting the symptoms to the crash. Be wary of anyone who promises a specific number.
Recovery and follow-up
Many people recover within weeks, but some have symptoms for months. Follow your provider's advice on rest and gradual return to activity, and keep follow-up appointments. Gaps in care can be used to argue the injury was minor.
Frequently asked questions
Can I get a concussion without hitting my head?
Yes. Rapid acceleration and deceleration in a crash can shake the brain even without head contact.
How long after an accident can concussion symptoms appear?
Symptoms can show up hours or days later. Report new symptoms to a doctor and mention the accident.
Do concussions show up on a CT scan or MRI?
Often they do not. Diagnosis is usually based on symptoms and a clinical exam, which is why good records matter.
