Benign Paroxysmal Positional Vertigo (BPPV)

Benign Paroxysmal Positional Vertigo (or BPPV) is the most common cause of vertigo, which is a false sensation of spinning.

– Benign – it is not life-threatening
– Paroxysmal – it comes in sudden, brief spells
– Positional – it gets triggered by certain head positions or movements
– Vertigo – a false sense of rotational movement

BPPV is a mechanical problem in the inner ear. It occurs when some of the calcium carbonate crystals (otoconia) that are normally embedded in gel in the utricle become dislodged and migrate into one or more of the 3 fluid-filled semicircular canals, where they are not supposed to be. When enough of these particles accumulate in one of the canals they interfere with the normal fluid movement that these canals use to sense head motion, causing the inner ear to send false signals to the brain.


Benigní paroxyzmální polohové závratě (BPPV)

CO JE BPPV? Benigní paroxyzmální polohové závratě (neboli BPPV) jsou nejčastější příčinou závratí, falešného pocitu točení.1 Benigní - neohrožuje život. Paroxysmální - přichází v náhlých, krátkých záchvatech. Polohové - vyvolávají je určité polohy hlavy nebo


VeDA Ambassadors

An ambassador is an enthusiastic and dedicated vestibular patient or professional, or the family member of a vestibular patient, who is interested in sharing his or her time and expertise to help elevate awareness for vestibular disorders. As an ambassador you are passionate about our cause and committed to keeping abreast of new, relevant issues that may impact the vestibular community.


Canalith Repositioning Procedure (for BPPV)

The Canalith Repositioning Procedure is also known as the "Epley maneuver." BPPV (Benign Paroxysmal Positional Vertigo) occurs as a result of displaced otoconia, which are small crystals of calcium carbonate (also referred to as "otoliths"


Causes of Dizziness

Dizziness, vertigo and disequilibrium are common symptoms reported by adults during visits to their doctors. They are all symptoms that can result from a peripheral vestibular disorder (a dysfunction of the balance organs of the inner ear) or central vestibular disorder (a dysfunction of one or more parts of the central nervous system that help process balance and spatial information). Although these three symptoms can be linked by a common cause, they have different meanings, and describing them accurately can mean the difference between a successful diagnosis and one that is missed.



There is increasing evidence on how sex hormones affect the inner ear. Many women report that hormonal fluctuations can trigger their vestibular symptoms. More research needs to be done to conclusively show a connection between hormonal changes and vestibular dysfunction, and until then there are few treatment options available.


About Vestibular Disorders

The vestibular system includes the parts of the inner ear and brain that process the sensory information involved with controlling balance and eye movements. If disease or injury damages these processing areas, disorders of dizziness or balance can result. Vestibular disorders can also result from, or be worsened by, genetic or environmental conditions, or occur for unknown reasons.

The most commonly diagnosed vestibular disorders include:
– Benign paroxysmal positional vertigo (BPPV)
– Vestibular migraine
– Labyrinthitis or vestibular neuritis
– Ménière’s disease
– Age-related dizziness & imbalance
– Vestibular damage due to head injury

Ear Anatomy

Overview The fluid within the inner ear's membranous labyrinth is called endolymph (endo-: inside or within). The fluid contained between the bony labyrinth and the membranous labyrinth is perilymph (peri-: around or about). These two
