Vertigo

Vertigo is the feeling that you or your environment is moving or spinning, when in reality you are motionless. There are a few common causes of vertigo, one of them being Benign paroxysmal positional vertigo (BPPV). BPPV is the most common form of vertigo and is characterized by the sensation of motion initiated by sudden head movements or moving the head in a certain direction. Vertigo may also be caused by inflammation within the inner ear (within the vestibular system), also referred to as labyrinthitis or vestibular neuritis. This is characterized by the sudden onset of vertigo and may be associated with hearing loss. The most common cause of labyrinthitis is a viral or bacterial inner ear infection.
Common symptoms of vertigo are vomiting and/or nausea, unsteadiness, and perspiration. If the vertigo symptoms are recurrent, as they commonly are, one's quality of life can seriously be impaired. Other symptoms include blurred vision, difficulty speaking, low levels of consciousness, and hearing loss. Disorders in the central nervous system may lead to permanent symptoms.
Treatment of vertigo depends on the underlying causes of the vertigo. BPPV is treated with the Epley Maneuver (seen in the video below) which can be performed by a doctor, physical therapist, or with a BPPV maneuver at home.
