vertigo		An illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. Vertigo may be associated with disorders of the inner ear; vestibular nerve; brainstem; or cerebral cortex. Lesions in the temporal lobe and parietal lobe may be associated with focal seizures that may feature vertigo as an ictal manifestation. (From Adams et al., Principles of Neurology, 6th ed, pp300-1) [ Books \| Images \| Discussion groups ]

T Brandt, RB Daroff - Annals of Neurology, 1980 Benign paroxysmal positional vertigo is a common disorder, with an estimated incidence of 160,000 new cases per year in the United States. Among patients seen in a general internal medicine outpatient clinic and in 2 sub-specialty dizziness clinics, vertigo was the most frequent category of dizziness, and benign paroxysmal positional vertigo was the most common cause of vertigo. DA Froehling, JM Bowen, DN Mohr, RH Brey, CW … - Mayo Clin Proc, 2000 Benign paroxysmal positional vertigo (BPPV) is the most common and most treatable cause of vertigo. In most cases, a simple maneuver that takes less than a few minutes to do resolves the problem. BPPV is caused by misplaced calcium carbonate crystals (otoconia) in the semicircular canal of the inner ear that have broken free from the utricle. When these crystals break free, they either remain loose in one of three different semicircular canals or attach to the hair cells within a canal. Ronald J. Tusa, MD, PhD Current Neurology and Neuroscience Reports 2001, 1:478-485 Positional vertigo is a common symptom characterized by sudden onset of brief episodes of intense vertigo triggered by rapid changes of head and body position.
