[Epilepsy and psychic seizures].
Various psychic symptoms as ictal manifestation have been found in epileptic patients. They are classified as psychic seizures within simple partial seizures, and subclassified into affective, cognitive, dysmnesic seizures and so on, although the subclassification is not yet satisfactory and almost nothing is known about their relationships with normal brain functions. In this presentation, the speaker picked ictal fear, déjà vu and out-of-body experience (OBE) from them and suggested that studies on these symptoms could uniquely contribute to the progress of cognitive neuroscience, presenting some results from the research and case study that he had been engaged in. Psychic seizures are prone to be missed or misdiagnosed unless psychiatrists with sufficient knowledge and experience on epilepsy care would not treat them, because they are subjective symptoms that are diverse and subtle, while they have some characteristics as ictal symptoms.
