Epilepsy surgery after treatment of pediatric malignant brain tumors

Seizures in children treated for a primary brain tumor: risk factors, evaluation and management

ABSTRACT 

Seizures may be a presenting symptom of a brain tumor in childhood or can occur as a complication of treatment or subsequent effect occurring years after completion of therapy. Seizures create a number of therapeutic challenges and represent a significant comorbidity that results in decreased quality of life. Treatment options may be limited by interactions with chemotherapy and/or increased susceptibility to side effects. Moreover, seizures in this patient population may be less responsive to the traditional therapies typically effective for nontumor related epilepsy. While the pathophysiology of tumor-related epilepsy remains unclear, advances are being made in our understanding of the possible mechanisms involved. Newer anticonvulsants and improved diagnostic tools with refined surgical techniques show promise for future treatment approaches.
