This change then sends altered signals to the brain which is perceived as dizziness. This is what causes the dizzy or giddy feeling when we spin around quickly in a circle.In BPPV the crystal position can change and can affect the movement of fluid and cilia. This movement is sensed by the nerves which is transmitted to the brain thus we perceive movement. When our head moves, the crystals move with it, causing the viscous fluid in the canal to swirl about, which, in turn, causes the hair-like cilia to move. There are tiny hair-like cells, called cilia which detect movement and transmit these signals about movement, position and balance to the brain. These canals are filled with a fluid which the crystals float in. Inside our inner ear, lies the parts of the vestibular system which is made up of three semicircular canals. They’re made of calcium, and they play a big role in our perception of movement and balance. In your inner ears, there is a collection of tiny crystals, called otoliths or otoconia. BPPV accounts for approximately 75% of all vertigo cases. The most common type of vertigo is called Benign Paroxysmal Positional Vertigo (BPPV). There are many causes of dizziness, including injury or dysfunction of your neck, disorders of your inner ear, and your cerebellum. Up to 70% of the population will suffer from some kind of vertigo during their lifetime. The maneuver moves the calcium crystals out of the sensing tube and into another inner chamber of the ear, where they do not cause symptoms.Vertigo is quite common, with an incidence of around 5-10%, and up to 40% for 40+ year olds. The disorder is likely caused by loose calcium carbonate crystals that move in the sensing tubes of the inner ear. "Despite this, we found it encouraging to think that YouTube could be used to disseminate information about this maneuver and educate more people about how to treat this disorder." Kerber and his colleagues are currently working on projects to test the effectiveness of video interventions on patient outcomes. "One shortcoming of the videos was that they did not include information on how to diagnose BPPV, and some of the comments indicate that people who do not have BPPV may be trying these maneuvers because of dizziness from other causes," Kerber said. People with dizziness also seem to be using the videos to treat themselves. Some comments showed that health care providers are using the videos as a prescribed treatment or to help patients learn about the maneuver. "But it was also good that the majority of the videos demonstrated the maneuver accurately." "It was good to see that the video with the most hits was the one developed by the American Academy of Neurology when it published its guideline recommending the use of the Epley maneuver in 2008 and then posted on YouTube by a lay person," Kerber said. They also reviewed the comments posted regarding the videos to see how the videos were used. "We found that accurate video demonstrations of the maneuver that health care providers and people with vertigo can use are readily available on YouTube."įor the study, Kerber and his colleagues searched YouTube for videos showing the Epley maneuver and rated their accuracy. Kerber, MD, of the University of Michigan Health System in Ann Arbor and a member of the American Academy of Neurology. "This type of vertigo can be treated easily and quickly with a simple maneuver called the Epley maneuver, but too often the maneuver isn't used, and people are told to 'wait it out' or given drugs," said study author Kevin A. MINNEAPOLIS – Watching videos on YouTube may be a new way to show the treatment for a common cause of vertigo, which often goes untreated by physicians, according to a study published in the July 24, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.īenign paroxysmal positional vertigo (BPPV) is an inner ear disorder that is a common cause of dizziness.
