Concussion after a car accident

The short answer

A concussion is a type of brain injury caused by a bump, blow or jolt to the head, or a hit to the body that makes the head move back and forth fast. In a car crash, that can happen even if your head never hits anything. Signs can take hours or days to show up. See a doctor after any crash, and get emergency care right away for danger signs like repeated vomiting or a headache that keeps getting worse.

What a concussion is

A concussion happens when a sudden movement makes the brain bounce around or twist inside the skull. That can change how the brain works for a while.

Only a doctor can tell you if you have one. Tell them about the crash, even if you think you feel fine.

Common signs to watch for

  • Headache
  • Feeling dizzy or having balance problems
  • Nausea or vomiting, mostly early on
  • Being bothered by light or noise
  • Vision problems
  • Feeling tired, foggy or slowed down
  • Trouble focusing or remembering things
  • Feeling anxious, irritable or sad
  • Sleeping more or less than usual, or trouble falling asleep

Why your medical records matter

Many concussion signs are things only you can feel, like headaches, fogginess or trouble sleeping. That makes your medical records very important. A doctor's notes describe your symptoms, the tests they did and the plan they gave you.

It can also help to ask a family member to write down changes they notice, like mood swings or forgetfulness. Follow up visits show whether things are getting better and how long the symptoms lasted.

What a concussion claim can include

  • Emergency care, doctor visits and any scans or tests
  • Care from specialists or therapists if your doctor sends you
  • Pay you lost while you needed to rest or work fewer hours
  • Ongoing care if symptoms last longer than expected
  • How the injury affects your memory, mood, sleep and daily routine

What to keep a record of

  • A daily symptom log with headaches, sleep and mood
  • Times you had trouble at work, like missing details or needing breaks
  • Every appointment, test and prescription
  • Notes from family or friends about changes they've seen
  • Your doctor's advice about rest, driving or going back to work

Common questions

Can I have a concussion if I didn't hit my head?

Yes. The CDC explains that a hit to the body that makes the head move back and forth quickly can cause a concussion. A sudden stop in a crash can do this.

How soon after a crash do concussion signs show up?

Some signs show up right away, but others can take hours or days to appear or be noticed. Watch for changes over the next few days and see a doctor if anything feels off.

Will a concussion claim cover time off work?

A claim may include pay you lost while you were recovering, if your records show the injury kept you from working. It's free to check your claim, and you don't have to go ahead.
