Benign Paroxysmal Positional Vertigo (BPPV)
The translation of BPPV is "temporary and benign vertigo caused by movement".
BPPV is characterized by a sense of movement triggered by certain head movements, which is much more intense than the actual movement's amplitude. While patients may experience mild instability at rest, they endure severe and brief vertigo attacks that typically start a few seconds after the triggering movement. Nausea and vomiting may also accompany. Although vertigo can be triggered by repeating triggering movements it gradually gets weaker.
“Despite its name suggesting a benign disease, BPPV can significantly disturb patients. If left untreated, the probability of recovery at the end of the first month is only 30%.”
BPPV is typically seen after the 50s. Women are affected twice as often as men. Head trauma, osteoporosis, vitamin D deficiency, the presence of other ear and vestibular diseases, and allergic rhinitis may be the underlying causes.
