Resumen

LEGIDO, Agustín  y  VALENCIA, Ignacio. Role of continuous EEG monitoring in the diagnosis of pediatric epilepsy. Medicina (B. Aires) [online]. 2009, vol.69, n.1, suppl.1, pp. 92-100. ISSN 1669-9106.

The diagnosis of epilepsy is basically clinical, but it frequently raises the differential diagnosis with non-epileptic events. The development of continuous EEG monitoring (CEEGM) in the past decades has allowed a better diagnosis of epileptic patients of all ages. In this paper we review the data available in the literature about the efficacy of the different modalities of CEEGM in the diagnosis of pediatric epilepsy, emphasizing our personal experience. In our studies the ambulatory CEEGM supplemented with video allowed to answer the question that prompted its request in 80% of patients diagnosed with epilepsy and in 83% of those with the suspected diagnosis of epilepsy. With ambulatory computer-assisted CEEGM those figures were 88% and 89%, respectively, and with inpatient video-CEEGM they were 82% and 51%, respectively. The latter is crucial in the evaluation of epilepsy patients who are candidates for surgical treatment. Inpatient video-CEEGM is also very important in the management of patients with acute encephalopathies admitted to the Intensive Care Units. Both, ambulatory or inpatient CEEGM, are very useful in the differential diagnosis of clinical epileptic versus non-epileptic events, as well as in the confirmation of the type of epilepsy or epileptic syndrome. The development of technological advances and new EEG modalities in the future will help to continue to consider electroencephalography as a very important technique in the study of brain function in patients with acute or chronic encephalopathies.
