Question 1

Which finding on posturography (CDP) suggests a vestibular use pattern?

Accepted Answer

Fall on conditions 5 and 6 with intact 1–4

Answer

Falling on conditions 5 and 6 (which require vestibular input) while maintaining balance on conditions 1–4 indicates a vestibular sensory organization deficit.

Question 2

What is the treatment of choice for posterior canal BPPV?

Accepted Answer

Epley canalith repositioning maneuver

Answer

The Epley maneuver repositions displaced otoconia from the posterior semicircular canal back into the utricle and resolves BPPV in the majority of cases.

Question 3

Meniere's disease is classically characterized by which tetrad of symptoms?

Accepted Answer

Tinnitus, aural fullness, sensorineural hearing loss, and episodic vertigo

Answer

The classic Meniere's tetrad includes episodic vertigo lasting 20 minutes to 12 hours, fluctuating low-frequency sensorineural hearing loss, tinnitus, and aural fullness.

Question 4

Oscillopsia is most commonly associated with which vestibular condition?

Accepted Answer

Bilateral vestibular hypofunction

Answer

Bilateral vestibular hypofunction impairs the VOR, causing the world to appear to bounce or oscillate during head movement (oscillopsia).

Question 5

Which medication class is most commonly used as a vestibular suppressant during acute vertigo episodes?

Accepted Answer

Anticholinergics and antihistamines

Answer

Anticholinergics (e.g., scopolamine) and antihistamines (e.g., meclizine) are the primary vestibular suppressants used for symptomatic relief of acute vertigo.
