What is the difference between labyrinthitis and bppv




















Physicians should pay particular attention to physical findings of the neurologic, head and neck, and cardiovascular systems. The cranial nerves should be examined for signs of palsies, sensorineural hearing loss, and nystagmus.

Vertical nystagmus is 80 percent sensitive for vestibular nuclear or cerebellar vermis lesions. Patients with peripheral vertigo have impaired balance but are still able to walk, whereas patients with central vertigo have more severe instability and often cannot walk or even stand without falling. In one study, 22 it was only 19 percent sensitive for peripheral vestibular disorders and did not correlate with more serious causes of dizziness not limited to vertigo such as drug-related dizziness, seizure, arrhythmia, or cerebrovascular events.

The Dix-Hallpike maneuver Figure 2 1 , 3 , 19 may be the most helpful test to perform on patients with vertigo. It has a positive predictive value of 83 percent and a negative predictive value of 52 percent for the diagnosis of BPPV. To perform the Dix-Hallpike maneuver, the patient initially sits upright. The examiner should warn the patient that the maneuver may provoke vertigo. After a two- to second latent period, the onset of torsional upbeat or horizontal nystagmus denotes a positive test for benign paroxysmal positional vertigo.

The episode can last 20 to 40 seconds. Nystagmus changes direction when the patient sits upright again. Information from references 1 , 3 , and Hyperventilation for 30 seconds may assist in ruling out psychogenic causes of vertigo associated with hyperventilation syndrome.

The tympanic membranes should be examined for vesicles i. Orthostatic changes in systolic blood pressure e. Laboratory tests such as electrolytes, glucose, blood counts, and thyroid function tests identify the etiology of vertigo in fewer than 1 percent of patients with dizziness. Physicians should consider neuroimaging studies in patients with vertigo who have neurologic signs and symptoms, risk factors for cerebrovascular disease, or progressive unilateral hearing loss.

In patients with isolated vertigo who also were at risk for cerebrovascular disease, 25 percent had caudal cerebellar infarcts. Neuroimaging studies can be used to rule out extensive bacterial infections, neoplasms, or developmental abnormalities if other symptoms suggest one of those diagnoses.

Conventional radiographs or cross-sectional imaging procedures may aid in the diagnosis of cervical vertigo i. Not all patients with vertigo need to be referred to a subspecialist. Family physicians should consider referral to the appropriate subspecialist e. Already a member or subscriber? Log in. Interested in AAFP membership? Learn more. Address correspondence to Ronald H.

Vestibular neuronitis VN is caused by inflammation of the vestibular nerve.

In these cases, referral to a neurologist is recommended. A careful history is required to elicit features of central or peripheral causes of vertigo. Physical examination involves a neurological, cardiovascular, eye and ear examination. Treatment is specific to the cause of vertigo.
