Headaches and fatigue are symptoms most people expect after a concussion. Dizziness, however, often catches people off guard. You could be feeling lightheaded, unsteady, or like the room is moving after a concussion. This is one of the most common symptoms we see at Vital Performance Care in Calgary, and it is very treatable with the right concussion physiotherapy and vestibular therapy.
Let’s take a closer look at what is happening in your brain and body.
Why Dizziness Happens After a Concussion
A concussion is a mild traumatic brain injury that disrupts how the brain communicates with the body. One of the systems most affected is the vestibular system, which controls balance and motion.
You can think of this system as your internal GPS for movement. It helps you understand where your head is in space, keeps your vision stable, and allows you to stay upright as you move through the world.
When this system is disrupted, the brain receives mixed signals. That mismatch often leads to dizziness, balance problems, and motion sensitivity. Many people notice they feel off balance, lightheaded, or unusually sensitive to busy environments and screens. Tasks like focusing their eyes or walking through grocery stores can suddenly feel overwhelming.
The Three Main Causes of Post-Concussion Dizziness
Not all dizziness is the same, which is why proper assessment is so important.
1. Vestibular Dysfunction and the VOR
The inner ear and brain normally work together to stabilize vision and balance through the vestibulo-ocular reflex (VOR). This reflex is responsible for keeping your vision clear and stable when your head is turning. After a concussion, this connection becomes less efficient. People often notice blurry vision when moving their head, difficulty tracking moving objects, and increased discomfort in crowded or visually busy environments. Vestibular therapy plays a major role in recalibrating this reflex.
2. Balance and Proprioception Changes
Your brain relies on vision, the inner ear, and body awareness from muscles and joints to maintain balance. After a concussion, the brain may struggle to combine these signals effectively. The result can be a persistent sense of wobbliness or instability. Everyday activities such as walking in the dark, turning quickly, navigating stairs, or even standing still may suddenly feel challenging.
3. Cervicogenic Dizziness (Neck-Related)
This is a factor many people do not expect. Concussions often involve a whiplash-type movement that affects the neck joints and muscles, leading to a condition known as cervicogenic dizziness. The top joints of the cervical spine are dense with mechanoreceptors that tell your brain where your head is in space. When the neck sends inaccurate position signals to the brain, dizziness can follow. This is why effective concussion physiotherapy often includes cervical spine treatment alongside vestibular rehabilitation.
Screening for BPPV After Impact
During a concussion assessment, it is also important to screen for Benign Paroxysmal Positional Vertigo (BPPV). The physical impact of a concussion can sometimes dislodge tiny calcium carbonate crystals within the inner ear canals. When these crystals move out of place, they cause intense, brief episodes of room-spinning vertigo, especially when rolling over in bed, tilting your head up, or bending down. Fortunately, BPPV is a highly treatable inner ear condition that a trained vestibular therapist can often resolve quickly using specific repositioning maneuvers.
How Vestibular Therapy Helps You Recover
Vestibular rehabilitation is a specialized and evidence-based physiotherapy approach designed to retrain the brain and restore normal balance function. Concussion care commonly includes:
- Vestibular rehabilitation
- Cervical spine therapy
- Graded exercise programs
- Vision and balance retraining
The goal is to retrain the nervous system gradually and safely.
What Treatment Actually Looks Like
Many people worry that therapy will make dizziness worse. In reality, avoiding movement often slows recovery, while guided and gradual movement helps the brain adapt.
Treatment often includes:
- Gaze stabilization exercises to retrain the connection between the eyes and inner ear so vision stays steady during head movement.
- Balance retraining to introduce progressive challenges that help the brain relearn how to trust the body.
- Gradual exposure to movement to reduce sensitivity by allowing the brain to adapt safely.
- Neck treatment through manual therapy and exercise to improve communication between the neck and brain.
- Graded cardiovascular exercise to help regulate the nervous system and support overall recovery.
A simple principle guides concussion rehabilitation: pacing and gentle movement speed recovery.
How Long Does Concussion Dizziness Last?
This is the question most people ask first. Some individuals recover within a few weeks, while others experience symptoms for several months. One of the strongest predictors of recovery time is early, targeted treatment. If dizziness lasts longer than two to three weeks, vestibular physiotherapy is strongly recommended. Starting sooner helps the brain adapt more efficiently.
Tips to Manage Dizziness at Home
During recovery, small daily adjustments can make a meaningful difference:
- Short walking breaks are often more helpful than complete rest.
- Limiting long screen sessions while taking regular visual breaks can reduce symptom flare-ups.
- Avoiding sudden head movements early on.
- Staying hydrated.
- Maintaining consistent sleep.
- Gradually increasing activity.
Consistency plays a major role in recovery.
When to Seek Concussion Physiotherapy in Calgary
Consider booking an assessment if dizziness lasts longer than a few days, if you notice balance problems or frequent stumbles, or if returning to work, sport, or driving feels difficult. Motion sensitivity, visual discomfort, or neck pain alongside dizziness are also strong signs that professional support could help.
The Takeaway
Dizziness after a concussion can feel unsettling and frustrating, but it is highly treatable. With the right combination of vestibular therapy, neck treatment, and progressive exercise, the brain can relearn balance and movement safely.
