The spinning or whirling sensation of vertigo can be rotary, a feeling similar to having just gotten off a merry-go-round. They may also experience it differently, depending on the movement that triggers the symptoms. People with BPPV may experience the specific sensation of vertigo in various ways. People experiencing vertigo because of inner ear problems, typically, also have nystagmus, or uncontrollable eye movement. People with BPPV experience vertigo, a sudden sensation that everything around them is spinning when it is not. This miscue causes nystagmus, a condition where the eyes move uncontrollably back and forth or up and down, making it seem like someone’s surroundings are spinning. When the brain compares this false message from the inner ear with information from the other senses and organs, it cannot make them match, so it recognizes it as a spinning sensation. This sends an incorrect message to the brain that the head is moving. As a result, when clumps of otoconia build up in the semicircular canals, they can make the motion-sensing fluid move when it should not. However, otoconia move along with gravity. The semicircular canals do not usually react to gravity. If enough otoconia accumulate in any of the canals, it can disrupt the fluid movement the canals use to detect head motion. They then move to the fluid-filled, motion-sensing semicircular canals. blockage of the anterior vestibular arteryīPPV usually occurs when calcium carbonate crystals, or otoconia, that sit in a gravity-sensing part of the ear called the utricle become dislodged. ![]() ![]() However, a few conditions may cause or influence BPPV, including: ![]() In many cases, BPPV seems to develop randomly.
