Dizziness and disequilibrium are common complaints reported by many people at Brainstorm. Importantly dizziness is not a disease but rather a symptom resulting from disturbance of the vestibular system. This may impair the person’s ability to change positions or move about without the imbalance of vertigo. Even more moderate dizziness may be debilitating enough to diminish a person’s quality of life both physically and socially. 

The standard outcome instrument to quantify dizziness symptoms is the Dizziness Handicap Inventory DHI. A neurological tool comprising of twenty-five questions. A score is calculated depending on the value of the response to the issue.
