Epileptic auditory illusions as reliable findings in the determination of the lateralization and localization of epileptogenic zone

The prevalence of EAA in the population with generalized epilepsy can be found higher than expected if a detailed evaluation of the population with generalized epilepsy can be performed, as in specific patient groups. Our results indicated that the epileptogenic zone was lateralized to the dominant hemisphere in all the patients with isolated auditory illusion or auditory illusion + elementary or complex auditory hallucinations, which suggests that auditory illusion can be a reliable tool in the determination of the lateralization and even localization of the epileptogenic zone.
