What type of vertigo can result from unequal pressure in the ears?

1. Alternobaric vertigo

2. Positional vertigo

3. Meniere's disease

4. Vestibular neuritis

The correct answer is: Alternobaric vertigo

Alternobaric vertigo occurs when there is a difference in pressure between the two ears, often experienced during rapid changes in altitude, such as during diving or flying. This condition is linked to the barometric pressure changes and affects the vestibular system, which is responsible for maintaining balance. When the pressure in one ear is different from the other, it can create a disorientation that results in vertigo. In contrast, positional vertigo is generally associated with changes in head position rather than pressure differences. Meniere's disease is characterized by episodes of vertigo, tinnitus, and hearing loss, but it is related to fluid accumulation in the inner ear rather than pressure discrepancies. Vestibular neuritis involves inflammation of the vestibular nerve, typically resulting from a viral infection, but does not primarily involve unequal pressure between the ears. Therefore, alternobaric vertigo is specifically linked to the phenomenon of unequal pressure and conveys the challenges faced by individuals, particularly those engaged in activities exposing them to rapid atmospheric changes.
