General Discussion
Benign Paroxysmal Positional Nystagmus is a disorder of the vestibular system in the middle ear that causes dizziness due to altered function of the semicircular canals, usually involving the posterior canal but sometimes involving the horizontal canal. The dizziness, which is accompanied by abnormal eye movements or nystagmus, occurs suddenly and without warning; thus, it is "paroxysmal". It is also "positional" because the symptoms increase with certain movements of the head or body. It is the position of the head, rather than the movement, that causes the symptoms.
