Benign positional vertigo occurs when there is an abrupt sensation that you are moving or the room around you is moving. This sensation is triggered by head positions such as lying on one side or tipping the head back. Positional vertigo is triggered by the actual position of the head, while in other disorders involving vertigo, the vertigo is triggered by movement of the head.
Examination is otherwise normal.
Treatment Usually, no treatment is required. Occasionally, medications such as antihistamines, anticholinergics, and sedative-hypnotics may be prescribed to reduce symptoms of vertigo . Avoid head positions that cause vertigo. Use caution in occupations where even short episodes of vertigo may be dangerous. Sometimes, gradually increasing the time spent in positions that cause vertigo causes the inner ear to adjust and decreases the positional vertigo.
