Q

What insufficiency may BPPV be confused with?

A

May be confused with Vertebrobasilar insufficiency.

For a diagnosis of VBI need other symptoms of impaired circulation in posterior brain associated with the vertigo:
e.g. visual disturbance
weakness
numbness

What is the Brandt-daroff exercise?

A

Start in an upright, seated position.
