Epilepsy (E) is common in all types of cerebral palsy (CP) and in some varieties it is the rule. The aim of this study is to evaluate the nature, course and prognosis of seizures in patients with E and CP. Clinical observations were performed on a group of 109 patients, from 2.5 to 17 years of age, 2/3 associated mental retardation. The results proved that all types of seizures can be observed at the patients with CP and the epileptic attacks can be controlled in most cases with polytherapy.
