Severe forms of dissociation or conversion can lead to events clinically often described as pseudo-seizures. Borderline personality disorder is a clinical condition which is often accompanied by a high susceptibility for dissociation and dissociative states are characterized by memory disturbance and perceptual alterations. We report a case of a patient with a complete anaesthesia, paralysis and amnesia for about 1 h. Within this time period we measured a bispectrum EEG index called BIS. Deepest recorded BIS value was 47. The described pattern of short but deep BIS reductions is completely discongruent to the findings during physiological sleep, during general anaesthesia, but very similar (and even more pronounced) to those during self-hypnosis. This makes former assumptions plausible that hypnosis and severe forms of dissociation (or conversion) may share common aetiologies.
严重的分离或转换形式可导致临床上经常描述为假性癫痫发作的事件。边缘型人格障碍是一种临床情况，通常伴随着高度易分离，分离状态的特点是记忆障碍和知觉改变。我们报告了一例患者，其经历了约 1 小时的完全麻醉、瘫痪和失忆。在此期间，我们测量了一种称为 BIS 的双谱脑电图指数。记录到的最深 BIS 值为 47。这种短暂但深度 BIS 降低的描述模式与生理睡眠、全身麻醉期间的发现完全不一致，但与自我催眠期间的发现非常相似（甚至更明显）。这使得以前的假设变得合理，即催眠和严重的分离（或转换）可能具有共同的病因。
