Vestibular Problems After Concussion: Symptoms, Causes, and Recovery

A concussion can cause much more than headaches or memory problems. Some people also develop dizziness, balance issues, motion sensitivity, nausea, or the feeling that the room is spinning.

These symptoms may point to vestibular problems after concussion.

The vestibular system helps your brain understand movement, balance, and spatial orientation. It works closely with your eyes, inner ears, muscles, and joints to help you stay steady and move through your environment. When a concussion disrupts that system, everyday activities such as walking, driving, working, shopping, or using a computer can suddenly become difficult.

The CDC recognizes dizziness, balance problems, and vision problems among the physical symptoms that can follow a mild traumatic brain injury or concussion.

Understanding why these symptoms happen, how they are evaluated, and what treatment may involve can help injured people take the next steps toward recovery.

What Are Vestibular Problems After a Concussion?

The vestibular system helps control balance and tells the brain where the body is in space.

Part of this system is located in the inner ear, while other parts involve pathways in the brain that process movement, visual information, and sensory input from the rest of the body.

After a concussion, communication between these systems can become disrupted. The result may be vestibular dysfunction after concussion, including dizziness, vertigo, imbalance, blurred vision, or difficulty tolerating movement.

Post-concussion vestibular dysfunction is not always caused by one single problem. Research suggests that symptoms may involve interactions between the peripheral vestibular system, central nervous system, and cervical spine, which is why careful evaluation can be important.

Why Balance Depends on More Than the Inner Ear

Good balance requires several systems to work together.

Your brain uses information from:

• The inner ears
• The eyes
• Muscles and joints
• The brain and spinal pathways that process movement

When those signals do not match, a person may feel dizzy, unstable, disoriented, or visually overwhelmed.

That is why concussion balance problems cannot always be explained by an inner-ear injury alone.

What Are the Symptoms of Vestibular Dysfunction After Concussion?

Vestibular symptoms can look different from one person to another.

Some people mainly experience spinning sensations. Others feel unsteady, have trouble walking, or become dizzy when exposed to moving visual scenes.

Dizziness and Vertigo

Dizziness after concussion is a common complaint.

A person may describe:

• Lightheadedness
• Unsteadiness
• A floating sensation
• Feeling as if the environment is moving
• Spinning sensations
• Dizziness when turning the head
• Symptoms when standing up or changing position

Vertigo is slightly different from general dizziness. It usually refers to the sensation that you or your surroundings are moving or spinning when there is no actual movement.

Vertigo after concussion may be triggered by changes in head position or may occur with other vestibular symptoms.

Balance and Walking Problems

A concussion may also affect a person’s ability to stay steady while standing or walking.

Possible problems include:

• Veering to one side
• Feeling unstable on stairs
• Difficulty walking in the dark
• Feeling as though the floor is moving
• Needing to hold onto walls or furniture
• Difficulty walking on uneven surfaces

The CDC includes dizziness and balance problems among common physical symptoms of mild TBI and concussion.

Visual and Motion Sensitivity

Some people feel relatively normal while sitting still but become symptomatic in busy environments.

Triggers may include:

• Grocery store aisles
• Crowds
• Scrolling on a phone
• Watching fast-moving video
• Driving
• Riding in a vehicle
• Looking quickly from side to side
• Moving through visually complex spaces

This is sometimes referred to as visual motion sensitivity.

Symptoms may include dizziness, nausea, headaches, blurred vision, eye strain, or disorientation.

For someone experiencing motion sensitivity after concussion, routine activities can become surprisingly exhausting.

What Causes Vestibular Problems After a Concussion?

There is no single explanation for every case of post-concussion dizziness.Several different mechanisms may contribute.

Possible causes include:

• Disruption of central vestibular pathways
• Inner-ear injury
• Problems coordinating eye and head movements
• Benign paroxysmal positional vertigo
• Migraine-related vestibular symptoms
• Neck-related dizziness
• Problems integrating sensory information

Modern reviews emphasize that post-concussive vestibular dysfunction may involve multiple systems rather than one isolated lesion.That is one reason simply saying “I feel dizzy” may not be enough to identify the underlying problem.

BPPV After Concussion

One possible cause of vertigo after head trauma is benign paroxysmal positional vertigo, commonly called BPPV.

BPPV can cause brief episodes of spinning when the head moves into certain positions.Symptoms may appear when:

• Rolling over in bed
• Looking upward
• Bending down
• Getting out of bed
• Turning the head quickly

BPPV after concussion is only one possible cause of dizziness, so positional vertigo should be evaluated rather than assumed.

Why Can Vestibular Symptoms Be Missed After a Concussion?

Vestibular problems are not always obvious. A person may look completely normal while sitting in a medical office yet feel unstable when walking through a crowded store or driving in traffic.

These symptoms may also be missed because:

• Headaches receive more attention.
• Neck or back injuries seem more urgent.
• The patient describes multiple symptoms simply as “dizziness.”
• Routine imaging does not explain the problem.
• Symptoms occur only during certain movements.
• Problems become more noticeable after returning to work or exercise.

The CDC also notes that concussion symptoms can be difficult to sort out and may be overlooked by the injured person, family members, or healthcare providers.

This can make post-concussion dizziness especially frustrating.

A person may know something feels wrong but have difficulty explaining exactly what is happening.

How Are Vestibular Problems After Concussion Diagnosed?

Diagnosing vestibular dysfunction often requires more than a routine scan.

Depending on the symptoms, a healthcare provider may assess:

• Balance
• Walking and gait
• Eye movements
• Head movements
• Visual tracking
• Coordination
• Positional dizziness
• Motion sensitivity
• Neurological function

Evaluation may involve different specialists depending on the suspected cause.

These may include:

• Neurologists
• Ear, nose, and throat specialists
• Vestibular therapists
• Physical therapists
• Concussion specialists
• Vision-related specialists when appropriate

Vestibular and oculomotor screening can help clinicians identify specific impairments that may be associated with prolonged concussion symptoms.

Can CT or MRI Show Vestibular Dysfunction?

Not always.

CT and MRI imaging can be important when doctors are looking for certain structural injuries, bleeding, fractures, or other serious problems.

However, vestibular symptoms after concussion may involve functional problems that are not clearly visible on routine imaging.

The CDC explains that healthcare providers diagnose mild TBI using symptoms and clinical testing and that a scan is not always necessary to diagnose concussion.

For that reason, symptoms and specialized examination can be just as important as imaging when evaluating persistent dizziness or balance problems.

How Are Vestibular Problems After Concussion Treated?

Treatment depends on what is causing the symptoms.

There is no one-size-fits-all approach.

Depending on the diagnosis, treatment may include:

• Vestibular rehabilitation therapy
• Balance exercises
• Gaze-stabilization exercises
• Gradual exposure to movement
• Treatment for BPPV
• Vision-related rehabilitation
• Management of vestibular migraine
• Treatment of neck injuries when relevant

A 2023 systematic review of randomized trials found that vestibular rehabilitation appears useful for reducing symptoms after concussion, although the studies varied in their methods and treatment approaches.

What Is Vestibular Rehabilitation Therapy?

Vestibular rehabilitation therapy is an individualized form of rehabilitation designed to improve problems involving balance, gaze stability, movement, and spatial orientation.

Exercises may be tailored to the specific symptoms and deficits found during evaluation.

Depending on the individual, therapy may involve:

• Balance training
• Controlled head movements
• Eye-head coordination exercises
• Gaze stabilization
• Habituation to movements that trigger symptoms
• Gradual exposure to visually busy environments

Research has found that vestibular rehabilitation can reduce perceived dizziness and improve certain outcomes in people with persistent symptoms after concussion, although individual results vary.

The goal is not simply to push through symptoms. Effective rehabilitation is usually based on the specific problem being treated.

How Long Do Vestibular Symptoms Last After a Concussion?

There is no universal recovery timeline.

Many people improve over time, but some experience persistent dizziness, balance issues, or motion sensitivity.

The CDC notes that concussion symptoms generally improve over time, while also recognizing that symptoms can vary significantly between individuals.

Recovery can depend on factors such as:

• The type of vestibular dysfunction
• Severity of the concussion
• Presence of neck injuries
• Migraine symptoms
• Visual problems
• Other neurological symptoms
• Response to rehabilitation

Persistent symptoms can interfere with:

• Driving
• Working
• Exercising
• Shopping
• Household responsibilities
• Social activities
• Independent mobility

If symptoms are continuing or getting worse, further evaluation may be appropriate rather than simply waiting for them to disappear.

Why Documentation Matters When Vestibular Problems Follow an Accident

Vestibular symptoms can be difficult to demonstrate because they are often invisible.

A person may appear normal in photographs or conversations while struggling with dizziness every time they drive, walk through a crowded area, or turn their head quickly.

When a concussion results from an accident caused by another party, documentation may help show how the injury has affected everyday life.

Relevant evidence may include:

• Emergency room records
• Neurology records
• Concussion specialist evaluations
• Vestibular assessments
• Physical therapy records
• ENT evaluations
• Balance testing
• Work restrictions
• Symptom journals
• Statements from family members or coworkers

Persistent vestibular problems may affect more than medical bills.

Depending on the circumstances, they may interfere with employment, driving, physical activity, independence, and quality of life.

That information can be relevant in a traumatic brain injury claim, particularly when future rehabilitation, lost income, or ongoing treatment is involved.
