title: [The clinical use of dynamic EEG in childhood].
abstract: A-EEG is an important recent technologic innovation in EEG recording that facilitates long-term monitoring. The system consists of a miniature cassette tape recorder and a video play-back unit, which permits the taped EEG to be reviewed (Brain Spy CH24, Micromed). Because it is extremely lightweight and portable, the system permits unrestricted activity during recording. On the other hand, this predisposes the recording to more artifacts than are seen in routine recordings. We examined 103 patients, aged 3 months-24 years, between July 1988 and July 1990. Patients were divided into three groups: group 1 included 61 subjects with evidence of epilepsy and clinically definite seizures; group 2 included 29 patients with recurrent episodes that were not clearly epileptic (suspected "pseudo epileptic"); group 3 included 13 subjects with psychiatric disorders. We found that the clinical utility of A-EEG in epileptic children was: 1) obtain better clinical and EEG characterization and circadian distribution of seizures in 17 cases (28%); 2) quantify epileptiform generalized abnormalities and their variations during the sleep in 6 cases (10%); 3) verify the efficacy of specific drug treatment such as Bzd and ACTH in 12 cases (20%). The role of A-EEG in non-epileptic children with pseudoseizures was to establish the epileptic or non epileptic nature of some ictal events by detecting EEG seizure patterns in 11 cases (38%). As to regard the group 3, A-EEG has permitted to study sleep architecture and REM sleep measures, especially in depressed children compared to normal children. We discuss advantages, drawbacks and clinical applications of A-EEG in child neurology and psychiatry vs conventional EEG.
