Electroclinical correlation in neonatal seizures.

A dissociation between clinical and electroencephalographic phenomena is often observable in neonatal seizures. This finding raises important questions, including those related to the management of these patients. Another characteristic of neonatal convulsions is represented by their increased tendency towards status epilepticus. In order to examine the electroclinical correlation and its possible relationship to the occurrence of status epilepticus, recorded video-electroencephalograms of 17 newborns were submitted to detailed analysis. Time of onset, duration and other characteristics of all clinical and electrical events were noted. Five degrees of correlation were observed, from constant concurrence to complete dissociation. Examining the role of different parameters, it was observed that the incidence of electric discharges related significantly to the occurrence of electroclinical dissociation.
