Concussion vs. Whiplash: What’s the Difference?

March 27, 2026

After a car accident, fall, or sports injury, many people are told they have either a concussion or whiplash (and sometimes both).

Because these injuries often happen together and share similar symptoms, it can be confusing to understand what’s actually causing your symptoms.

In this article, we’ll break down the key differences between a concussion and whiplash, how they’re related, and how physical therapy can help.

This is Blog #4 in our series about Concussion Rehab Therapy.

What Is a Concussion?

A concussion is a mild traumatic brain injury (mTBI) that occurs when the brain moves rapidly inside the skull.

This can happen from:

• A direct blow to the head
• A fall
• A sports injury
• A sudden acceleration or deceleration (like a car accident)

Common concussion symptoms include:

• Headaches
• Dizziness
• Balance problems
• Nausea
• Sensitivity to light or noise
• Difficulty concentrating

What Is Whiplash?

Whiplash is a neck injury caused by a rapid back-and-forth movement of the head and neck.

This commonly occurs during:

• Car accidents (especially rear-end collisions)
• Sports injuries
• Falls

Whiplash affects the muscles, joints, and ligaments of the neck.

Common symptoms include:

• Neck pain and stiffness
• Headaches (often starting at the base of the skull)
• Reduced range of motion
• Muscle tightness
• Pain with movement

Key Differences Between Concussion and Whiplash

While they often occur together, they affect different parts of the body.

Concussion

• Affects the brain
• Impacts processing, balance, and coordination
• Often causes dizziness and cognitive symptoms

Whiplash

• Affects the neck (cervical spine)
• Impacts muscles, joints, and movement
• Often causes neck pain and tension headaches

Why Do These Injuries Often Happen Together?

In many injuries, especially car accidents or sports collisions, the head and neck are both affected.

When the head moves suddenly:

• The brain shifts inside the skull → concussion
• The neck experiences rapid force → whiplash

Because of this, it’s very common to have both injuries at the same time.

Overlapping Symptoms

This is where things can get confusing.

Both concussion and whiplash can cause:

• Headaches
• Dizziness
• Balance problems
• Difficulty concentrating
• Neck pain

For example:

• A headache may come from the brain (concussion)
• Or from the neck (whiplash)
• Or both

Why the Neck Is So Important After a Concussion

One of the most overlooked factors in concussion recovery is the neck.

Even if you’ve been diagnosed with a concussion, untreated neck issues can continue to cause:

• Headaches
• Dizziness
• A feeling of being “off”
• Difficulty turning your head

How Physical Therapy Helps

Because concussion and whiplash often overlap, it’s important to evaluate both the brain and the neck.

At Gordon Physical Therapy, we assess:

• Neck mobility and muscle tension
• Balance and coordination
• Vestibular (inner ear) function
• Eye movement and visual tracking

Treatment may include:

Neck Treatment

• Improve mobility
• Reduce stiffness and tension
• Address headache triggers

Vestibular Rehabilitation

• Reduce dizziness and motion sensitivity

Balance Training

• Improve stability and confidence

Gradual Return to Activity

• Help you safely return to work, sports, and daily life

When Should You Seek Treatment?

You should consider an evaluation if you’re experiencing:

• Persistent headaches
• Neck pain or stiffness
• Dizziness or balance problems
• Symptoms lasting more than 1–2 weeks
• Difficulty returning to normal activities

Treating both the concussion and the neck often leads to faster, more complete recovery.

Concussion vs Whiplash FAQ Section

Is whiplash the same as a concussion?

No. A concussion affects the brain, while whiplash affects the neck. However, they often occur together.

Can whiplash cause dizziness?

Yes. Neck dysfunction can contribute to dizziness and a feeling of being off balance.

Can you have a concussion without hitting your head?

Yes. A sudden movement of the head (such as in a car accident) can cause a concussion even without direct impact.

Why do I have both neck pain and headaches after a concussion?

Neck injuries are very common with concussions and can contribute to headaches and other symptoms.

What is the best treatment for concussion and whiplash?

Treatment often includes a combination of physical therapy for the neck, vestibular rehabilitation, and gradual return to activity.
