We analyzed the interrelation between etiology, the presence and seriousness of epileptic seizures (ES) and the possible causes of refractoriness. This is a prospective study using the clinical diagnosis of a child neurologist, who attested to the presence of unilateral motor lesions. We compared the electroencephalographic findings in patients with or without epileptic seizures, and investigated if among the former, these seizures were controlled or not, their likely etiology and risks of refractoriness. EEG background activity on the lesion and contralateral side was analyzed, in addition to the presence of concomitant epileptiform activity. Encephalon MRIs of all the patients were studied to correlate etiology and the control or not of epileptic seizures. The disorganization of bilateral EEG activity correlated with the difficult-to-control epileptic seizures. Suitably organized background activity contralateral to the lesion is a good prognosis in relation to epileptic seizures. Focal epileptogenic activity does not necessarily predispose to epileptic manifestation. The MRI is more important in determining etiology than in prognosing epileptic seizures. This study used a multidisciplinary approach involving child neurologists, a physical therapist and a neuroradiologist. This meets the criteria of multidisciplinarity of the Postgraduate Program in Health Sciences / O objetivo do nosso trabalho foi estudar pacientes com hemiparesia, cong?nitas e adquiridas, seus aspectos cl?nicos e epidemiol?gicos, a presen?a ou n?o de crises epil?pticas e os achados eletrencefalogr?ficos e de neuroimagem por Resson?ncia Nuclear Magn?tica. Tentando relacionar a etiologia ? presen?a e gravidade de crises epil?pticas e as poss?veis causas de refratariedade. Trata-se de um estudo prospectivo a partir do diagn?stico cl?nico por um neurologista infantil que atestou a presen?a de les?o motora unilateral. Compararam-se os achados eletrencefalogr?ficos em pacientes sem ou com crises epil?pticas, e dentre esses ?ltimos, se h? ou n?o controle das crises, sua prov?vel etiologia e riscos de refratariedade. Analisou-se a atividade de base do EEG do lado da les?o e contra lateral a esta, al?m da presen?a de atividade epileptiforme concomitante. Estudaram-se as RNM do enc?falo realizadas em todos os pacientes, tentando relacionar a etiologia e controle ou n?o de crises epil?pticas. A desorganiza??o da atividade de base bilateral no EEG correlacionou-se com crises epil?pticas de dif?cil controle. A atividade de base adequadamente organizada contra lateral a les?o ? de bom prognostico em rela??o ?s crises epil?pticas. A atividade epileptog?nica focal n?o necessariamente predisp?e a manifesta??o epil?ptica. A RNM ? mais importante na determina??o da etiologia do que no progn?stico das crises epil?pticas. A realiza??o deste estudo foi concretizada pela abordagem multidisciplinar, envolvendo neurologistas infantis, fisioterapeuta e neurorradiologista. Este aspecto preenche os requisitos de multidisciplinaridade do programa de p?s-gradua??o em Ci?ncias da Sa?de
