Convulsive pseudoseizures thought to represent psychiatric disease can usually be detected early if they are considered in the epileptologist's differential diagnosis. No single diagnostic criterion for this behavioural disorder is known to be pathognomonic. Epilepsy and all physiological explanations have to be thoroughly ruled out and positive evidence of relevant psychopathology has to be gathered.The presence of pseudo seizures often heralds severe psychopathology, most frequently major affective disorder and major personality disorder, and occasionally, factitious disorder. Pseudoseizures can coexist with epileptic seizures and are often triggered by anticonvulsant toxicity.Diagnostic problems are more likely to be encountered in patients with frontal or parietal epilepsies, and in patients whose severe psychopathology is refractory to psychiatric intervention.
被认为代表精神疾病的惊厥性假性发作，如果在癫痫学家的鉴别诊断中加以考虑，通常可以早期发现。目前还没有一种单一的诊断标准被认为是这种行为障碍的特征性表现。必须彻底排除癫痫和所有生理解释，并收集相关精神病理学的阳性证据。假性发作的出现常常预示着严重的精神病理学，最常见的是重性情感障碍和重性人格障碍，偶尔也会出现诈病。假性发作可与癫痫发作并存，常由抗癫痫药物毒性引起。在额叶或顶叶癫痫患者以及严重精神病理学对精神干预有抗性的患者中，更有可能出现诊断问题。
