Vestibular Problems After a Brain Injury: Dizziness, Balance Issues and Vertigo

Yes. Dizziness, vertigo and balance problems can happen after sustaining a concussion or traumatic brain injury. These symptoms may arise from vestibular dysfunction, visual motion sensitivity, BPPV, neck injury, migraine features, brain injury effects or a combination of several problems after the accident.

Vestibular symptoms can be deeply disruptive to a person's ability to function. A person may appear physically recovered but feel unsteady in a grocery store, dizzy while driving, nauseated after screen use, unsafe on stairs or overwhelmed by movement in their surroundings. These symptoms can also overlap with headaches, neck pain, visual problems, cognitive fatigue and anxiety, which makes the condition harder to explain in a short medical appointment.

Our Ontario brain injury lawyers represent people whose concussions and traumatic brain injuries have caused lasting dizziness, balance problems, vestibular dysfunction and difficulty returning to work or normal daily life.

Can a Brain Injury Cause Dizziness or Balance Problems?

Yes. Dizziness and balance problems are common after concussion and traumatic brain injury. The injured person might feel lightheaded, off balance, unsteady, nauseated, visually overwhelmed or as though the room is spinning. Some people feel worse when they turn their head, look up, bend down, walk through a busy store, ride in a car, use a computer or move through a crowded place.

The Model Systems Knowledge Translation Center’s factsheet on balance problems after traumatic brain injury explains that TBI can affect the vestibular system and cause balance problems, dizziness or a spinning sensation.

Dizziness after TBI should not be dismissed as a vague complaint. Balance depends on the brain, inner ear, eyes, neck, muscles, joints and sensory feedback working together. A traumatic injury can disrupt more than one part of that system at the same time.

What Is the Vestibular System?

The vestibular system helps the body understand motion, balance and spatial orientation. It encompasses structures in the inner ear that sense head movement and position. It also depends on pathways in the brain that process those signals and coordinate them with vision, posture and movement.

When the vestibular system is working properly, a person can turn their head, walk, read signs, move through crowds, drive, climb stairs and keep their vision stable while their body is moving.

After a concussion or TBI, that system may become disrupted. The brain might struggle with integrating signals from the inner ear, eyes, neck and body. The result can be dizziness, imbalance, visual motion sensitivity, nausea, poor coordination or a feeling that the person is not steady in space.

The problem is not always limited to the inner ear. It can involve the brain’s processing of vestibular information, visual tracking, neck injury, migraine features, fatigue, anxiety or a combination of several factors.

How Concussion and TBI Affect Balance

Balance is not controlled by one structure alone. The body relies on vestibular information from the inner ear, visual information from the eyes, proprioceptive information from the neck, muscles and joints, and brain processing that combines those signals into a stable sense of position and movement.

Concussions can disrupt this integration. The person may become more dependent on vision for balance, more sensitive to motion, slower to adjust to head movement, or less able to filter visual information in busy settings.

More serious traumatic brain injuries can also affect areas involved in balance, coordination, eye movement, arousal, attention and motor control. A person with TBI may struggle with dizziness because of vestibular dysfunction, visual disturbance, brainstem or cerebellar involvement, neck injury, medication effects, blood pressure changes, headaches, sleep disruption or cognitive overload.

This is why dizziness after an accident should be assessed carefully. “Dizzy” can describe several different problems, and the treatment depends on the cause.

Dizziness, Vertigo and Visual Motion Sensitivity After TBI

People often use “dizziness” to describe several different sensations.

Dizziness can mean lightheadedness, fogginess, imbalance, floating, swaying, nausea or a feeling of being disconnected from the surroundings.

Vertigo usually means a spinning or moving sensation. The person may feel that the room is spinning, that their body is moving when it is not, or that the ground is shifting.

Visual motion sensitivity means symptoms are triggered by movement in the visual environment. Busy stores, scrolling screens, traffic, crowds, patterned floors, escalators or fast-moving images can provoke dizziness, nausea, headache, fogginess or panic-like symptoms.

The Living Concussion Guidelines section on vestibular, balance, dizziness and vision dysfunction describes persistent vertigo, dizziness, imbalance and visual disturbance as common symptoms after concussion and notes that they are often associated with objective vestibular impairments.

These symptoms can make ordinary activities feel unpredictable.

Why Busy Places, Screens and Driving Can Make Symptoms Worse

Vestibular symptoms often become worse when the brain has to process motion, light, noise and visual information at the same time.

Busy stores are a common trigger for symptoms. We have seen many clients struggle with grocery stores which combine bright lights, shelves, patterns, movement, carts, people, signs, turning, stopping and starting. For someone with post-concussion vestibular dysfunction, that environment can be exhausting and disorienting.

Screens can also aggravate symptoms. Scrolling, small text, rapid visual changes, brightness and sustained focus can trigger dizziness, nausea, headache or cognitive fatigue. The person may tolerate a few minutes but deteriorate with longer use.

Driving adds another layer. The brain must process moving traffic, mirrors, speed, lights, lane changes, head turns, peripheral motion and decision-making. A person with vestibular symptoms may feel unsafe driving, especially at night, in heavy traffic, on highways or when turning their head quickly.

BPPV, Vestibular Migraine and Cervicogenic Dizziness After an Accident

Dizziness after an accident can have more than one cause.

Benign paroxysmal positional vertigo, or BPPV, is a common cause of vertigo. It often causes brief spinning sensations triggered by changes in head position, such as rolling over, looking up, bending down or getting out of bed. The Mayo Clinic overview of BPPV notes that BPPV is one of the most common causes of vertigo and that, when there is a known cause, it can be linked with a blow to the head.

Vestibular migraine can also cause dizziness, vertigo, motion sensitivity, visual sensitivity, nausea and headache symptoms. Some people experience vestibular symptoms even when headache is not the dominant complaint.

Cervicogenic dizziness refers to dizziness associated with neck injury or neck-related dysfunction. After a collision or fall, a person may have both concussion symptoms and neck injury. Neck pain, restricted motion and altered sensory input from the cervical spine can contribute to dizziness and imbalance.

These conditions can overlap. For example, a person injured in an accident may have BPPV, post-concussion vestibular dysfunction, neck-related dizziness, migraine features, visual symptoms and cognitive fatigue at the same time. That overlap is one reason careful assessment is so important.

Vestibular Problems After Concussion or Mild TBI

Vestibular problems are common after concussions and mild traumatic brain injuries.

Someone who suffered a concussion could have dizziness, balance problems, visual sensitivity, nausea, motion intolerance, headaches, fatigue and difficulty concentrating. These symptoms can be present even when CT or MRI imaging is normal.

Concussion is diagnosed clinically. Imaging is often used to rule out more urgent problems, not to prove every functional symptom. A normal scan does not mean the person’s dizziness, imbalance or visual motion sensitivity is imaginary.

For more detail about concussion injuries, see our guide to mild traumatic brain injury in Ontario.

Vestibular Symptoms, Cognitive Fatigue and Symptom Overlap

Vestibular symptoms and cognitive fatigue often interact. When the brain is working hard to maintain balance, stabilize vision and process movement, ordinary activities require more effort. Reading, driving, shopping, walking through crowds and using screens can drain mental energy quickly.

A person struggling with vestibular dysfunction may become tired not because they were physically active, but because their brain was constantly trying to interpret confusing sensory information. Dizziness can increase cognitive load. Cognitive fatigue can then make dizziness harder to manage.

These cycles can interfere with work and daily life. A person may handle a short errand but be unable to continue the day. They may complete a short meeting but need to lie down afterward. They may use a screen for part of the morning and then struggle with headache, fogginess or nausea.

For more detail on how mental effort and symptom flares can affect daily function, see our guide to cognitive fatigue after a brain injury.

How Vestibular Problems Are Assessed After TBI

Vestibular problems after a brain injury can be assessed by several types of health professionals, depending on the symptoms.

Assessments can involve a family doctor, emergency physician, neurologist, physiatrist, vestibular physiotherapist, occupational therapist, ENT specialist, optometrist, neuro-optometrist or other rehabilitation provider.

The assessment can include a history of the dizziness, balance testing, eye movement testing, gait assessment, positional testing for BPPV, vestibulo-ocular reflex testing, visual tracking assessment, neck assessment and review of symptom triggers.

The details matter. Dizziness when rolling in bed is different from dizziness in a busy store. Spinning vertigo is different from lightheadedness. Visual motion sensitivity is different from faintness. Balance problems on stairs are different from nausea after screen use.

Vestibular Therapy After Brain Injury

Vestibular therapy can be part of treatment after concussion or traumatic brain injury.

Treatment depends on the diagnosis. For BPPV, treatment may involve canalith repositioning manoeuvres. For vestibular hypofunction, treatment may involve gaze stabilization and balance exercises. For visual motion sensitivity, therapy may involve gradual exposure to visual motion and exercises designed to improve tolerance.

The Johns Hopkins vestibular therapy page describes vestibular rehabilitation as therapy used to reduce dizziness from inner ear disorders and neurological conditions, including BPPV, post-concussion syndrome, vestibular migraine and traumatic brain injury.

Vestibular therapy is not simple “exercise.” The wrong activity, wrong dose or wrong progression can worsen symptoms. Proper programs will reflect the person’s diagnosis, tolerance, symptom triggers and recovery stage.

Some people improve with treatment. Others continue to have symptoms, especially where dizziness overlaps with migraine, neck injury, visual dysfunction, cognitive fatigue, psychological trauma or more serious brain injury.

How Vestibular Symptoms Affect Work and Daily Life

Vestibular symptoms interfere with daily function even when the injured person looks normal.

At work, dizziness and visual motion sensitivity can make screens, meetings, fluorescent lighting, warehouse floors, ladders, driving, multitasking, customer interaction and busy environments difficult. A person may need reduced hours, screen breaks, a quieter workspace, modified duties or gradual exposure to work demands.

In daily life, vestibular symptoms can affect grocery shopping, cooking, cleaning, driving, stairs, childcare, exercise, social events, medical appointments and travel. Some people avoid stores, crowds, highways, elevators, escalators or fast visual motion because symptoms flare.

Balance problems can also create safety concerns. A person who is unsteady may be at greater risk of falls, especially on stairs, uneven ground, ice, busy sidewalks or in low light.

Why Vestibular Problems Are Often Misunderstood

Vestibular problems after brain injury are often misunderstood because they fluctuate and are triggered by specific environments.

The person may look fine at home but become dizzy in a grocery store. They may speak normally during a medical appointment but develop symptoms while driving home. They may tolerate a quiet room but deteriorate under fluorescent lights, screen use, noise or visual motion.

This creates unfair assumptions. Family members may think the person is avoiding activities. Employers may interpret dizziness as anxiety or lack of effort. Insurers may focus on normal imaging or normal appearance while missing the functional pattern.

Vestibular symptoms are also difficult to describe. “Dizzy” can mean spinning, swaying, floating, nausea, imbalance, fogginess or visual disorientation. The more specific the evidence, the easier it is to understand the true effect of the injury.

How Vestibular Symptoms Are Documented

Vestibular symptoms can be documented through treatment records, rehabilitation notes, testing, work records and observations from people who know the injured person well.

Medical records can show ongoing complaints of dizziness, vertigo, imbalance, nausea, visual motion sensitivity or falls. Vestibular physiotherapy records can describe test findings, symptom triggers, tolerance, treatment response and functional limitations.

Occupational therapy records are helpful for describing how symptoms impact a person's daily activities, driving, screen use, errands, household tasks and work capacity. Work records can show reduced hours, accommodation needs, failed return-to-work attempts or inability to tolerate visually busy environments.

Family observations can be very important. A spouse, parent, adult child or close friend may be able to describe the before-and-after difference: avoiding stores, holding walls on stairs, stopping driving, needing recovery after appointments, losing confidence walking outside or becoming overwhelmed by movement and noise.
