Benign Paroxysmal Positional Vertigo

What are some of the common diagnoses that can cause vertigo?

Benign Paroxysmal Positional Vertigo (“BPPV”)
Occasionally, particles form or settle in one of the semicircular canals of the inner ear. The particles tend to sink to the lowest point of the canal. Certain positional changes, such as rolling to one’s side in bed, can result in reorientation of the canal in space, causing the particles to sink to the new “bottom.” This typically results in a sensation of “room spinning” that lasts for less than one minute.
