Eye movements
How the eyes hold a target, follow movement, and shift attention.
Dizziness, Vertigo & Balance · Stony Brook, NY
The World Should Hold Still.
Dizziness and vertigo can feel similar, but they don't always come from the same place. At Leon Chiropractic in Stony Brook, Dr. Jared Leon uses a detailed brain, balance, eye-movement and vestibular evaluation to better understand what may be contributing to the problem and determine an appropriate path forward.

The Brain–Balance Connection
Dizziness Is a Symptom. The Question Is Why.
Balance depends on the brain integrating vestibular information from the inner ear, vision, proprioceptive and somatosensory information, eye and head movement coordination, and central nervous system processing.
Think of balance like a three-way conversation between your eyes, inner ears and body. Your brain has to listen to all three, compare their information and create one stable picture of where you are in space.
A dizzy feeling does not automatically point to one cause. The purpose of a careful evaluation is to understand the pattern and identify contributing factors—not to make assumptions from a symptom alone.

Different Patterns · Different Questions
Not All Vertigo Is BPPV. And Not All Dizziness Is Vertigo.
Positional vertigo can sometimes involve displaced particles within the inner ear and may respond to an appropriate repositioning maneuver. Other patterns can involve different vestibular, visual, migraine-associated, post-concussion, or central mechanisms and may require a different rehabilitation approach.
These examples are educational. A website cannot determine which pattern is present; an appropriate clinical evaluation is needed.

Visual Motion Sensitivity
Fine at Home. Dizzy at Costco? There's a Reason.
Large stores, patterned aisles, crowds, scrolling environments, and busy visual fields ask the eyes and balance system to process a tremendous amount of motion and spatial information. For someone who is visually sensitive, that mismatch can feel disorienting even when a quiet room feels comfortable.

A Person-First Vestibular Evaluation
What Dr. Leon Looks At.
Testing is selected according to the individual's history and presentation. The goal is to understand how the relevant systems are functioning together—not to run everyone through the same list of equipment.
Head and eye coordination
How vision responds while the head is moving.
Balance under different conditions
How stability changes when visual or surface information is altered.
Vestibular function
How inner-ear motion information is used for orientation and stability.
Visual motion sensitivity
How the system responds to patterns, crowds, screens, and moving scenes.
Proprioception
How accurately the body senses position and movement.
Cerebellar and neurological function
How timing, coordination, and sensory information are organized.
Cervical and spinal contribution
Considered when the neck or spine is clinically relevant to the presentation.
When useful, measurements may include computerized balance assessment or Motion Guidance® to examine stability, sensory integration, and movement control. Explore the related technology in the Functional Recovery Lab™.
