Which of the following is a potential symptom of flicker vertigo?

1. Headache

2. Loss of consciousness

3. Severe nausea

4. Visual disturbances

The correct answer is: Visual disturbances

Flicker vertigo is often associated with visual stimuli, particularly rapid changes in light patterns, which can induce a sensation of dizziness or imbalance. Visual disturbances are a hallmark symptom of this condition, as the brain struggles to process the conflicting information from rapidly flickering lights. This can lead to experiences such as seeing spots or blurred vision, contributing significantly to the sensation of vertigo. While headache, loss of consciousness, and severe nausea could occur in other contexts, they are not specifically tied to flicker vertigo as core symptoms. The essence of this condition lies predominantly in the visual aspect, making visual disturbances the most relevant answer in this scenario.
