[Influence factors on correct diagnosis of non-epileptic paroxysmal disorders in childhood].
To investigate the influence factors on correct diagnosis of non-epileptic seizures(NES) in childhood, we analyzed 24 h ambulatory electroencephalography(AEEG) and clinical features of the attacks in 159 children with NES. The results showed that 28% of all patients were identified as NES plus epileptic seizures. Epileptiform EEG discharges were observed in 10% of pure NES children. Abnormal findings on neurodiagnostic evaluation were obtained in 32% of NES plus epileptic seizure groups, in 11% of pure NES groups. Unnecessary anti-epileptic drugs were received in 18% of pure NES children and the kind or doses of the medicines were increased in 50% of NES plus epileptic seizure children who had been mistaken for refractory epilepsy. The influence factors on correct diagnosis of NES are mainly; variability of non-epileptic seizure expression, interictal epileptiform EEG discharges, neurologic abnormal findings, and anti-convulsant abuse.
