What causes BPPV?

The particles shift around when you move your head in certain ways, such as:

Bending over to pick up something
BPPV is more common in older people and in women.
What are the symptoms of BPPV?
Symptoms come on suddenly when you move your head. The symptoms of BPPV are:

The maneuver is done by following the clockwise order of the red arrows below.
To do the Epley maneuver do the following and hold each position for about 30 seconds:

Lie down on your back with your head still turned to the right and let your head hang off the end of the table or bed
Turn your head to the left
