EPILEPSY IN PEDIATRIC-PATIENTS - SELECTIO N OF INVESTIGATIONS

Epilepsy is a chronic condition whose diagnosis rests on clinical and electroencephalographic criteria. Computed tomography or magnetic reso nance imaging demonstrates a cause in 25% of cases. An international c lassification has been developed that is useful for evaluating the pro gnosis, the course, and the effect of treatments. Although the pathoph ysiology of epilepsy has not yet been elucidated, it is hoped that rec ently-developed functional imaging and genetic techniques will shed ne w light on this problem. Although neuropsychologic studies can be of u se for localizing the epileptic focus, few age-specific reference valu es have been reported. Laboratory tests are indicated when occasional seizures or metabolic disorders are suspected, as well as in epileptic children with worsening seizures or possible side effects of drugs.
