Can a Car Accident Cause a Concussion Without Hitting Your Head?

After a car accident, many people assume they cannot have a concussion because their head never hit the steering wheel, window, dashboard, or another object.

But can you get a concussion in a car accident without hitting your head? Yes.

A concussion can occur when the force of a collision causes your head and brain to move rapidly back and forth, even without a direct blow to the head. According to the Centers for Disease Control and Prevention (CDC), a concussion is a type of mild traumatic brain injury (TBI) that can result from a hit to the body that causes rapid movement of the head and brain.

For people involved in car accidents throughout Northeast Ohio, understanding the signs of a possible concussion is important, especially because symptoms aren’t always obvious immediately after a crash.

How Can a Car Accident Cause a Concussion Without Head Impact?

During a collision, your vehicle may stop or change direction suddenly, but your body continues moving with the force of the crash.

Your seat belt helps restrain your body, but your head and neck can still move rapidly forward, backward, or side to side. This sudden acceleration and deceleration can cause the brain to move or twist inside the skull.

The CDC explains that this rapid movement can cause chemical changes in the brain and may stretch or damage brain cells.

In other words, your head does not necessarily have to strike something for your brain to experience the forces that can cause a concussion.

Can Whiplash and a Concussion Happen Together?

Yes. The forces involved in a car accident can potentially affect both the neck and brain.

Whiplash occurs when sudden force causes rapid movement of the neck. It is particularly common in motor vehicle crashes, including rear-end collisions.

A concussion involves the brain, while whiplash primarily affects structures in the neck. Because the same crash can produce both types of injury, symptoms may overlap.

For example, both conditions may be associated with symptoms such as:

• Headaches
• Dizziness
• Neck discomfort
• Difficulty concentrating
• Fatigue

This is one reason it can be difficult to determine the cause of symptoms on your own after a car accident.

What Are the Signs of a Concussion After a Car Accident?

Concussion symptoms vary from person to person. Some symptoms may begin immediately, while others may not become noticeable until hours or even days after the injury.

Possible concussion symptoms can include:

• Headache or pressure in the head
• Dizziness or balance problems
• Nausea
• Sensitivity to light or noise
• Blurred or double vision
• Feeling tired or having little energy
• Difficulty concentrating
• Memory problems
• Feeling slowed down or “foggy”
• Changes in sleep
• Irritability or other emotional changes

You also do not have to lose consciousness to have a concussion. 

Can Concussion Symptoms Be Delayed After a Car Accident?

Yes.

One of the most important things to understand about a possible concussion after a car accident is that feeling okay immediately after the crash doesn’t necessarily mean you’re injury-free.

The CDC reports that some mild TBI and concussion symptoms occur immediately, while others may develop hours or days later.

You may leave the accident scene feeling relatively normal and later notice a headache, dizziness, trouble concentrating, unusual fatigue, sensitivity to light, or other changes.

That makes it important to pay attention to how you feel in the hours and days following a collision.

When Should You Seek Emergency Care?

Some symptoms following a car accident may indicate a more serious brain injury and require immediate medical attention.

The CDC recommends calling 911 or going to an emergency department for concussion danger signs such as:

• A headache that gets worse and does not go away
• Repeated vomiting
• Seizures or convulsions
• Increasing confusion, agitation, or unusual behavior
• Slurred speech
• Weakness, numbness, or decreased coordination
• Difficulty waking up or staying awake
• One pupil appearing larger than the other
• Double vision

When in doubt about potentially serious symptoms after a collision, seek emergency medical care.

Should You Get Checked After a Northeast Ohio Car Accident?

If you’re experiencing symptoms following a car accident, don’t dismiss them simply because you never hit your head.

A concussion is a brain injury, and a healthcare provider can evaluate your symptoms and determine whether further testing, treatment, or referral is appropriate. The CDC recommends that people with a mild TBI or concussion be evaluated by a healthcare provider.

At Ohio Therapy Centers, we help patients throughout Northeast Ohio get evaluated following car accidents and other injuries. Depending on your injuries and individual needs, your care plan may include chiropractic care, physical rehab, diagnostic evaluation, and other appropriate services.

Early evaluation can also help identify other injuries that may have occurred during the same collision, including whiplash, neck injuries, back injuries, and other musculoskeletal problems.

Frequently Asked Questions About Car Accident Concussions

Can you get a concussion without hitting your head?

Yes. A forceful hit to the body can cause the head and brain to move rapidly enough to result in a concussion, even without direct head impact.

Can a rear-end collision cause a concussion?

Potentially. A rear-end collision can cause sudden movement of the head and neck. If enough force causes rapid movement of the brain within the skull, a concussion may occur.

Do you have to lose consciousness to have a concussion?

No. A person can experience a concussion without ever losing consciousness.

How soon do concussion symptoms appear after a car accident?

Some symptoms can appear immediately, while others may take hours or days to become noticeable.

Should I get evaluated if I feel dizzy or have headaches after a car accident?

New or worsening symptoms following a collision should not be ignored. A healthcare provider can evaluate your symptoms and determine whether additional care is needed. Seek emergency care immediately for serious concussion danger signs.

Get Evaluated After a Northeast Ohio Car Accident

You don’t have to hit your head to suffer a concussion in a car accident.

If you’ve recently been involved in a crash and are experiencing headaches, dizziness, neck pain, difficulty concentrating, or other new symptoms, consider getting evaluated rather than waiting for the problem to disappear on its own.
