Ictal conduction aphasia and ictal angular gyrus syndrome as rare manifestations of epilepsy: The importance of ictal testing during video-EEG monitoring

摘要

The aim of these two case reports is to demonstrate that a predefined, structured, multimodal clinical bed-side testing during seizures in a long-term video-EEG monitoring setting facilitates diagnosis of complex neuropsychological syndromes. To the best of our knowledge, we present the first case of conduction aphasia as the sole ictal semiology, and a patient with focal seizures producing an angular gyrus syndrome in the speech dominant hemisphere. The relevance of diagnosing ictal aphasic and angular gyrus syndromes and localizing the symptomatogenic zone is discussed. Current pathophysiological concepts are presented regarding conduction aphasia and Gerstmann's syndrome.
