Resumos

São analisados os EEG de 65 crianças com diversos tipos de crises convulsivas ocorrendo nos primeiros 12 meses de vida. Alterações eletrencefalográficas foram registradas em 55 (84,5%), sendo o EEG normal em 10 casos (15,5%). A disritmia paroxística por onda "sharp" focal foi assinalada em 27 pacientes (41,5%); a disritmia paroxística por onda espícula focal em 3 (4,6%); ondas delta em 27 (41,5%); desorganização do ritmo em 3 (4,6%); depressão da atividade elétrica cerebral em 7 (10,7%) e alterações eletrencefalográficas de tipo hipsarritmia em 2 (3%). São feitas considerações a respeito dos prováveis mecanismos responsáveis pela propagação das descargas convulsiógenas no EEG dêsses pacientes, assim como a eventual correlação eletroclínica.

The electroencephalographic findings in 65 patients with convulsive disorders occurring during the first year of life were analysed. Abnormal EEG tracings were recorded in 55 patients (84.5%). Focal sharp waves were recorded in 27 (41.5%); focal spike waves in 3 (4.6%); delta waves in 27 (41.5%); disorganization (big build-up) of the electrical activity in 3 (4.6%); depression of the cerebral rhythms in 7 (10.7%) and hypsarrhytmic patterns activity in 2 patients (3%). Some considerations are made in regard to the mechanisms of the spread of the original discharges, as well as the electroclinical correlation.

ABSTRACT

The electroencephalographic findings in 65 patients with convulsive disorders occurring during the first year of life were analysed. Abnormal EEG tracings were recorded in 55 patients (84.5%). Focal sharp waves were recorded in 27 (41.5%); focal spike waves in 3 (4.6%); delta waves in 27 (41.5%); disorganization (big build-up) of the electrical activity in 3 (4.6%); depression of the cerebral rhythms in 7 (10.7%) and hypsarrhytmic patterns activity in 2 patients (3%). Some considerations are made in regard to the mechanisms of the spread of the original discharges, as well as the electroclinical correlation.
