A 2-year-old girl, diagnosed with traumatic brain injury and epilepsy following car trauma, was followed up for 3 years (a total of 15 recordings taken at 0, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 14, 19, 26, and 35 months). There is still no clear guidance on the diagnosis, treatment, and prognosis of children with disorders of consciousness. At each appointment, recordings included the child’s height, weight, pediatric Glasgow Coma Scale (pGCS), Coma Recovery Scale-Revised (CRS-R), Gesell Developmental Schedule, computed tomography or magnetic resonance imaging, electroencephalogram, frequency of seizures, oral antiepileptic drugs, stimulation with subject’s own name (SON), and median nerve electrical stimulation (MNS). Growth and development were deemed appropriate for the age of the child. The pGCS and Gesell Developmental Schedule provided a comprehensive assessment of consciousness and mental development; the weighted Phase Lag Index (wPLI ) in the β-band (13–25 Hz) can distinguish unresponsive wakefulness syndrome from minimally conscious state and confirm that the SON and MNS were effective. The continuous increase of delta-band power indicates a poor prognosis. Interictal epileptiform discharges (IEDs) have a cumulative effect and seizures seriously affect the prognosis.

2岁大儿童长期意识障碍的脑电图评估：3年随访

一名2岁女孩被诊断出汽车外伤后有脑外伤和癫痫病，并随访了3年（在0、2、3、4、5、6、7、9、10时共拍摄了15张录音，11、12、14、19、26和35个月）。关于意识障碍儿童的诊断，治疗和预后尚无明确指南。每次约会时，记录都包括孩子的身高，体重，小儿格拉斯哥昏迷量表（pGCS），昏迷恢复量表修订版（CRS-R），格塞尔发育时间表，计算机断层扫描或磁共振成像，脑电图，癫痫发作频率，口服抗癫痫药药物，具有受试者自己名字的刺激（SON）和正中神经电刺激（MNS）。生长发育被认为适合儿童的年龄。pGCS和Gesell发展时间表对意识和智力发展进行了全面评估；加权相位滞后指数（wPLI）在β波段（13–25 Hz）可以将无反应的清醒综合症与最低意识状态区分开，并确认SON和MNS有效。三角带功率的持续增加表明预后不良。发作间期癫痫样放电（IED）具有累积效应，癫痫发作严重影响预后。
