To properly treat BPPV, a specialist will also need to determine which type of BPPV someone has.

This also helps to determine which ear and which canal the displaced otoconia are occurring.īy some estimates, between 60% and 90% of all cases of BPPV involve the posterior semicircular canal. While someone is experiencing vertigo, the specialist will carefully watch their nystagmus for specific patterns that allow for confirmation of BPPV. The specialist will get a person to move their head in certain ways to see what movements cause symptoms. They may then refer people to a specialized health professional, such as an ear, nose, and throat doctor or vestibular rehabilitation therapist.

However, the uneasy feeling of vertigo can cause other symptoms such as: Vertigo is the primary symptom that BPPV causes. Some people with BPPV are symptom-free between spells of dizziness, but others continue to feel a lack of balance all or most of the time. The type of vertigo BPPV usually causes will last for 1 minute or less. Most people who wake up with vertigo tend to have BPPV. getting up after lying down, especially for a long time.In most cases, BPPV prompts vertigo only after certain types of movement or actions that cause the head to change position in relation to gravity, such as: Vertigo can also make it feel as though the ground is tilting up and down, a sensation similar to being on a boat.Ī further description of vertigo is that it can make people who are trying to get out of bed feel like they are falling back into bed, and people getting into bed feel like they are falling through the bed. 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.
