Medical Conditions - Benign Paroxysmal Positional Vertigo

Benign paroxysmal positional vertigo is the most common vertigo due to precise head position changes. It is the cause of the sudden spinning sensation and is characterized by brief periods of slight to severe dizziness. It is because the crystals seen in the otolith organs are dislodged. In that case, they move into the semicircular canals in the inner ear, which are sensitive to the changes in head position, causing dizziness.
