Summary
AI-generated from the abstractPositive autoscopic phenomena such as autoscopy, heautoscopy, and out-of-body experiences occur in various diseases and in healthy individuals but are underreported in focal epilepsies. In a group of 14 patients with ictal lateralized autoscopic phenomena, 12 (85.7%) had an epileptic focus on the opposite side of the brain from where the autoscopic image appeared. This suggests that when a person with epilepsy sees a double or an image of themselves to one side during a seizure, the seizure focus is likely in the opposite brain hemisphere.

Abstract
Positive autoscopic phenomena - autoscopy, heautoscopy and out-of-body experience - may occur in a variety of diseases and also in physiological conditions. They are a rare but probably underreported phenomenon in focal epilepsies. Here, we investigate whether ictal lateralized autoscopic phenomena give lateralizing information about the underlying epileptic focus. We present the cases of seven patients from our center who experienced ictal lateralized autoscopic phenomena and analyzed their focus lateralization and localization of the underlying brain lesion. In addition, we reviewed seven cases published in German and English language literature. In the total group of 14 patients with ictal lateralized autoscopic phenomena, 12 (85.7%) of them had a well-defined epileptic focus contralateral to the side of the autoscopic appearance. Therefore, the data point to an association between ictal lateralized autoscopy and contralateral epileptic focus.
