Benign paroxysmal positional vertigo
"It can be triggered by any action which stimulates the posterior semi-circular canal which may be:
- Tilting the head
- Rolling over in bed
- Looking up or under
- Sudden head motion
- Post head injury
BPPV may be made worse by any number of modifiers which may vary between individuals:
- Changes in barometric pressure - patients often feel symptoms approximately two days before rain or snow
- Lack of sleep (required amount of sleep may vary widely)
Brandt-Daroff Exercise for Vertigo
- Move into the lying position on one side with your nose pointed up at about a 45-degree angle.
- Remain in this position for about 30 seconds (or until the vertigo subsides, whichever is longer), then move back to the seated position.
- Repeat on the other side.
People using this exercise usually are instructed to do 20 repetitions of the exercise at least twice a day.
