Predictors of Hippocampal, Cerebral, and Cerebellar Volume Reduction in Childhood Epilepsy

Abstract

Significant brain volume reduction is present in children with epilepsy. A component of this reduction is due to acquired insults. The reduction is seen even in children with infrequent seizures over a brief time, suggesting an innate structural abnormality. When evaluating possible etiologic factors in the development of hippocampal volume reduction, one must control for total brain volume. We have confirmed the association of complex febrile convulsions with unilateral hippocampal volume reduction.
