Abstract: | We describe a 43-year-old neurologically intact patient who reported episodes of diplopia and oscillopsia associated with a right-beating nystagmus and a skew deviation. These symptoms and signs were related to a left posterior epileptic EEG discharge. We suggest that these ocular motor signs derived from an ictal activation of the vestibular cortex, which in turn activated descending projections to the vestibular nuclei, leading to both a dynamic (right-beating nystagmus) and a static (skew deviation) vestibular imbalance. |
