Vertigo is defined as which of the following?

Vertigo is defined as which of the following?

• A. Visual disturbance
• B. Hearing loss
• C. Illusionary sense of movement
• D. Numbness

Answer: (C)

Vertigo is the illusion of movement, often a spinning sensation, even when you’re actually still. This occurs when the brain gets conflicting signals about motion from the inner ear’s vestibular organs, the eyes, and body sensors, leading to a false sense that you or the surroundings are moving. That emphasis on an illusory sense of movement is why this option is the best description. The other ideas describe different problems—visual disturbances involve sight, hearing loss affects the auditory system, and numbness is about loss of sensation—none of which define vertigo.
