If you think you might have BPPV, complete this DHI (Dizziness Handicap Inventory) to see how severe your symptoms are.

The "Dizziness Handicap Inventory" (DHI) is a validated tool used to asses the degree of disability associated with any cause of dizziness.

Circumstances that may exacerbate symptoms include rapid temperature changes (like a hot shower or freezer section of the grocery store), fluorescent lighting, loud environments, watching TV with rapid camera movement, seeing someone 'talk with their hands', or driving down a road with shadows and bright spots caused by trees. Altitude changes, wind currents, pressure changes and being over-tired may also worsen symptoms.

Symptoms of BPPV are almost always precipitated by a change in head position. Getting out of bed and rolling over in bed are two common "problem" motions. Some people feel dizzy and unsteady when they tip their heads back to look up. An intermittent pattern of these symptoms is usual. About 20% of all dizziness is due to BPPV. The most common cause of BPPV in people under age 50 is head injury. About 50% of dizziness in older people is due to BPPV. In half of all cases, BPPV is idiopathic, which means that it occurs for no known reason. BPPV is also associated with migraine.

Most practices that evaluate substantial numbers of dizzy patients use questionnaires to quantify symptoms. One of the most commonly used "standardized questionnaires" is the Dizziness Handicap Inventory (DHI). Developed by Dr. G.P. Jacobson and Dr. C.W. Newman, 1990.
