How can you tell the difference between peripheral and central vertigo?
The duration of attacks is most helpful in distinguishing between central and peripheral causes; vertigo associated with vertebrobasilar insufficiency typically lasts minutes, whereas peripheral inner ear causes of recurrent vertigo typically last hours.
How do you evaluate central vertigo?
The Dix-Hallpike test can help distinguish central vertigo from peripheral vertigo. During the test, the clinician rotates the patient’s head 45 degrees to one side and then helps the patient to quickly lie back down. If rotational nystagmus is observed, the test is considered positive for benign positional vertigo.

How to take a hint on Central vertigo?
Vertical skew (T est of S kew) These tests were combined and have since been used as a tool to identify posterior circulation stroke: the Head Impulse, Nystagmus, Test of Skew (HINTS). 2 A single central finding on any of the 3 components “rules-in” a posterior circulation stroke, and further testing/treatment is indicated.
How to diagnose Vertigo in the emergency department?
For example, the absence of corrective saccade on the head impulse test is indicative of a central cause of vertigo, but the saccade will also likely be absent in any patient not currently symptomatic. Hold the patient’s head, allowing their mandible to rest and relax into your palms. Ask the patient to fixate on an object (ie, your nose).
What are the diagnostic features of a skew deviation?
Skew deviation has the following diagnostic features: (1) acquired hypertropia, (2) associated cerebellar or brainstem disease, and (3) lack of alternative etiology for hypertropia. Skew deviation is believed to represent an abnormal ocular tilt reaction (Fig.
What happens when a Vertigo test is negative?
During the test, the clinician rotates the patient’s head 45 degrees to one side and then helps the patient to quickly lie back down. If rotational nystagmus is observed, the test is considered positive for benign positional vertigo. If the test is negative, CNS dysfunction may be indicated. [ 12] Peripheral vertigo presents with the following:
