[Possibilities of error in EEG in sleep and consciousness (electroencephalographic observations in 153 children)].

The study concerns the EEG records of 153 children, aged within 1 and 4 and suffering from different neuropsychiatric disorders. Particularly during the first stages of sleep, graphoelements of epileptogenic morphology have been recorded in considerable amount. Obviously they were present in the records of clinically epileptic patients but they appeared also in the records of several patients having never suffered from epileptic seizures. The Authors suggest extreme caution in considering "epileptogenic" EEG patterns evoked by sleep in those children who are not clinically epileptic.
