Psychogenic nonepileptic seizures (PNES), a form of functional neurological symptom disorder (FNSD), are very rarely seen in genuine, electroencephalography (EEG)-confirmed sleep. However, they are more commonly reported as a nocturnal occurrence, likely from a state that is misidentified as sleep (termed by some as "pseudosleep"). Sleep state can be helpful to distinguish FNSD from other neurological disorders. Pseudo-cataplexy, a form of "psychogenic" narcolepsy, "pseudo-parasomnia" and PNES can have a similar presentation. PNES and posttraumatic stress disorder (PTSD) frequently share previously experienced psychological trauma, and therefore the sleep abnormalities found in PTSD may be similarly present in PNES. Future research should use EEG monitoring to evaluate the sleep physiology of patients with FNSD such as PNES, as insights into sleep abnormalities may enable further understanding of the etiology and manifestations of PNES.
心因性非癫痫性发作（PNES）是功能性神经症状障碍（FNSD）的一种形式，在真正的、经脑电图（EEG）证实的睡眠中极为罕见。然而，它们更常被报告为夜间发作，可能源于一种被误认作睡眠的状态（有些人称之为“假睡眠”）。睡眠状态有助于将FNSD与其他神经系统疾病区分开来。假性猝倒，一种“心因性”发作性睡病的形式，“假性异态睡眠”和PNES可能有相似的表现。PNES和创伤后应激障碍（PTSD）经常有共同的既往心理创伤经历，因此PTSD中发现的睡眠异常可能同样存在于PNES中。未来的研究应使用EEG监测来评估FNSD患者（如PNES患者）的睡眠生理，因为深入了解睡眠异常可能有助于进一步理解PNES的病因和表现。
