Without treatment, the usual course of the illness is lessening of symptoms over a period of days to weeks, and sometimes there is spontaneous resolution of the condition. ![]() A doctor’s diagnosis of BPPV can be reassuring, especially when people understand that help is available to relieve their symptoms. People may think they are seriously ill for example, they may fear they are having a stroke. The onset of BPPV may be abrupt and frightening. While the hallmark of BPPV is vertigo associated with changes in head position, many people with BPPV also feel a mild degree of unsteadiness in between their recurrent attacks of positional vertigo. Vertigo can cause the person to feel quite ill with nausea and vomiting. If they tilt their head back or forward while walking, they may even fall, risking injury. People can fall out of bed or lose their balance when they get up from bed and try to walk. People with BPPV can experience a spinning sensation - vertigo - any time there is a change in the position of the head. The otoconia move to the lowest part of the canal, which causes the fluid to flow within the SCC, stimulating the balance (eighth cranial) nerve and causing vertigo and jumping eyes (nystagmus). The otoconia will not cause a problem when located in an SCC until the person’s head changes position, such as when looking up or down, going from lying to seated or lying to seated in bed, or when rolling over in bed. Otoconia will occasionally drift into one of the SCCs, usually the posterior SCC given its orientation relative to gravity at the lowest part of the inner ear. ![]() If the crystals become detached, they can flow freely in the fluid-filled spaces of the inner ear, including the semicircular canals (SCC) that sense the rotation of the head. BPPV occurs when tiny calcium crystals called otoconia come loose from their normal location on the utricle, a sensory organ in the inner ear.
