The idea that YouTube could help with any medical disorder sounds outrageous. But in the case of benign paroxysmal positional vertigo (BPPV), treatment through YouTube is entirely possible.
That's because the treatment of BPPV usually involves moving your head in a specific manner in order to realign the calcium crystals in your ear. When these crystals, known as otoliths, are out of place, they distort your perception of motion; by realigning them, you can cure your vertigo.
While you might not want to jump onto YouTube to seek out treatments for most disorders, the video above and the four other top videos for curing BPPV follow the exact maneuver developed and recommended by the American Academy of Neurology.
