A direct head impact is not required, the rapid acceleration and deceleration of a crash can cause a concussion (mild traumatic brain injury) on its own. Early evaluation, careful return-to-activity guidance, and treatment of the neck component all matter.
Symptoms can show up right away or develop days later. If you notice any of these, get evaluated.
Treatment plans are personalized. Here are common approaches we use for this type of injury.
Concussion symptoms that are not managed in the first 1 to 2 weeks are more likely to become post-concussion syndrome. Most recover fully with structured early care, including treatment of the cervical injury that almost always rides along.
Yes. A concussion can occur in a car accident with no direct head impact. The rapid acceleration-deceleration of the crash causes the brain to shift inside the skull, which produces the same mild traumatic brain injury as a direct blow. This is one reason concussion screening is recommended after any moderate or severe collision, even without an obvious head strike.
Concussion symptoms after a car accident include headache or pressure in the head, dizziness or balance problems, nausea, sensitivity to light or sound, blurred vision, trouble concentrating or remembering, fatigue, sleep changes, and irritability or mood changes. Symptoms typically appear within 24 hours of the crash, though some develop over the first few days as inflammation peaks.
Most car accident concussions resolve within 7 to 14 days with relative rest, symptom management, and a structured return to activity. Symptoms persisting beyond 4 weeks are classified as post-concussion syndrome and benefit from a coordinated plan that addresses the cervical spine injury, vestibular system, and graded activity, because the neck injury that rides along with the concussion is often the symptom driver after week two.
Yes, once any emergency red flags have been ruled out. The cervical spine is injured in nearly every car accident concussion, and the lingering headaches, dizziness, and brain-fog of post-concussion syndrome are often driven as much by the neck injury as by the brain injury itself. A chiropractor experienced in accident care evaluates both, treats the cervical and vestibular components, and coordinates referral to neurology or your primary care provider when warranted.
