Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common causes of dizziness.
Vertigo, often described as a spinning sensation, can last for just a few moments, but it may recur and vary in intensity. In some cases, it’s self-limiting, while in others, it can significantly impact daily life. Symptoms of BPPV often include nystagmus (involuntary eye movements), nausea, vomiting, and hearing disturbances.
BPPV is thought to occur due to the displacement of calcium carbonate crystals, known as otoliths, within the inner ear. These crystals can become dislodged and move into the semicircular canals, disrupting normal balance signals to the brain. This displacement can be triggered by factors such as head trauma, aging, or an inner ear infection like labyrinthitis.
- Canalolithiasis Theory: Otoliths are free-floating within the semicircular canals.
- Cupulolithiasis Theory: Otoliths attach themselves to the crista ampullaris in the semicircular canals.
Diagnosing and Treating BPPV
An accurate diagnosis requires a detailed history, physical examination, and specific canal tests. Since there are many potential causes of vertigo, proper screening is essential to rule out other conditions.
While BPPV is often self-limiting, treatment is highly effective using the Epley maneuver (also known as the Canalith Repositioning Maneuver). This technique involves moving the patient through specific positions to guide the displaced otoliths back to their proper location, helping to restore balance and reduce vertigo.
Our sense of balance and spatial orientation is essential for proper brain function, and vertigo challenges this delicate system. At Brainstorm Rehabilitation, our team of trained therapists and technicians are trained to assess and treat vertigo, helping patients regain their stability and improve their quality of life.
