Visual perseveration (VP) is defined as persistence or recurrence of visual images, when the stimulus is no longer present. We report three patients with occipital cortical lesions in the right hemisphere and VP. Electroencephalography showed epileptic abnormalities in all cases. In one patient synchronous electroencephalic recordings during the onset of palinopsia-a subtype of VP-revealed, that VP was associated with a clear cut right occipital seizure with a secondary diffusion of the discharge over both hemispheres, which has not been reported in combination with the onset of palinopsia heretofore. In all three patients sensory seizures have to be considered as probable cause of VP.
视觉 perseveration(VP)被定义为当刺激不再存在时视觉图像的持续或重现。我们报告了三名右半球枕叶皮质病变并伴有 VP 的患者。脑电图显示所有病例均有癫痫异常。在一名患者中,在 Palinopsia(VP 的一种亚型)发作期间进行的同步脑电图记录显示,VP 与明确的右侧枕叶癫痫发作相关,放电随后扩散到双侧半球,这种情况此前尚未见与 Palinopsia 发作相关的报道。在所有三名患者中,感觉性癫痫发作都被认为是 VP 的可能原因。
