Patient's head is rotated to one side by approximately 45 degrees. Dix-Hallpike is performed in the following way ( Watch Video): Once BPPV is suspected based on history, a maneuver can be performed called Dix-Hallpike to confirm BPPV as a diagnosis. Go through the BPPV Flowchart to Determine Type and Treatment! Viral infections, osteoporosis, head trauma, and vitamin D deficiency are risk factors for BPPV. The end result is a spinning sensation which stops when the free-floating particles stop moving. However, when these particles become free-floating, they keep moving which essentially makes the inner ear tell the brain that the head is still turning even if it isn't. When a wave motion occurs, the buoy moves with the wave motion, but quickly settles out once the wave passes. The analogy would be a buoy in the ocean. Such particle movement is how the inner ear tells the brain that a head turn just happened. When a person turns the head, these anchored particles sway and than stop quickly. Normally, these particles are anchored within the inner ear and therefore their motion is limited. Found within the semi-circular canals of the inner ear (see image below), such free-floating particle wreak havoc with a person's balance, especially given that the semi-circular canals are analogous to a gyroscope and help the brain determine where the head is located in space relative to gravity. No associated symptoms (no hearing changes, aural fullness, ear ringing)īPPV occurs when particles which are normally anchored within the inner ear break free.Period of relative normalcy in between dizzy attacks.May cause nausea and vomiting if vertigo severe enough.Usually does not last more than a few minutes.Triggered by position change, typically turning.The key characteristics common to patients suffering from BPPV include: However, the MOST common cause of spinning dizziness is a condition called Benign Paroxysmal Positional Vertigo, also known as BPPV which accounts for about 20% of all dizziness. Watch Video on How the Inner Ear Balance System Works heart/vessel problem (ie, cardiac rhythm problems, stenosis of the carotid artery, etc).brain/spine problems (ie, stroke, brain tumor, etc).medication side effects(hypertension and neuro/psych medications are the most common).inner ear problems (ie, BPPV and Meniere's).

As such, diagnosis requires a good history and potentially LOTS of testing. It is a sensation that is felt only by the patient and nobody else. As such, it is important that your doctor precisely determines what dizziness means for a given person and obtain information on when, how long, how often, and anything that may trigger a dizzy attack.įiguring out what is causing a person's dizziness can be quite difficult because a doctor can't touch it, can't see it, can't feel it, can't smell it, etc. Even seizures and migraine headaches are sometimes reported as dizziness. Others may describe it as feeling 'drunk' or room-spinning.

Some people call their sense of dizziness or imbalance as a feeling of light-headedness. People experience dizziness in many different ways. BPPV - Benign Paroxysmal Positional Vertigoīy Dr.
