Dizzy, unsteady or "off," and told everything looks normal?
"Dizzy" is a symptom, not a diagnosis. Feeling unsteady, lightheaded, or uncomfortable in busy places can come from several different problems, and they are often interrelated. Working out which ones are involved, and what triggers each, is what decides what to treat first.
Assessment and care at Venn Med, Midtown Toronto. Patients come from across the GTA and Ontario, and some travel from further afield for an intensive program.
What it is
Your brain answers three questions every second: where am I in relation to gravity, where is my body in space, and where is the world around me? Imagine reaching for a stair in the dark that isn't there. That jolt is what a mismatch feels like. When the answers are slightly off, many times a day, people feel dizzy, foggy, tense or tired, and busy places can become overwhelming.
Several problems can produce inaccurate signals:
The inner-ear canals, which sense head rotation;
The otoliths, the inner-ear sensors for gravity and straight-line motion;
The neck (cervicogenic), where joint and muscle sensors tell the brain where your head sits on your body;
Circulation, including blood pressure and heart-rate changes on standing, and blood flow to the brain;
The eyes and visual system, including eye movements, focusing and over-reliance on vision;
Prediction errors, where the brain's forecast no longer matches what the senses report.
When dizziness persists on most days for three months or more, it may be PPPD, a functional condition. Read more on our FND page. It is real, common and treatable, and it needs to be identified, because treating it like an inner-ear problem alone tends to stall.
Why standard tests miss it
Standard exams often miss small errors in eye movements, balance and how signals are combined. Enough small errors together can overwhelm the brain's ability to compensate.
What we measure
We measure how your eyes, balance and posture reflexes, and muscle tone are working, and screen for physical limits such as blood flow, then put the findings together. We look at whether each task is done efficiently, quickly, accurately and for long enough. That tells us which mechanisms are driving your dizziness, what triggers them, and what to train first.
Common questions
Why am I still dizzy after a concussion?
Concussion can affect the inner ear, eye movements, neck input, circulation and how the brain combines these signals. Each needs different treatment, so finding which are involved comes first.
What is the difference between dizziness and vertigo?
Vertigo is a false sense of spinning or movement. Dizziness is broader and includes lightheadedness, unsteadiness and feeling “off.” Both are symptoms, not diagnoses.
Why do busy places make me dizzy?
When inner-ear or body signals are unreliable, many people lean on vision. Busy scenes such as grocery stores, traffic or scrolling screens can then overload the system and bring on dizziness, fog or fatigue.
Do I need a referral?
No. Anyone can enquire. Please send previous medical reports and test results ahead of your assessment.
When to get assessed
Consider an assessment if you have:
Dizziness or imbalance lasting more than a few weeks
Symptoms in busy visual environments, with head turns, or when tired
Tried therapy before and stalled.
If your dizziness isn't improving, start your enquiry.
