The relationships between structural brain abnormalities and epilepsy are poorly understood. Even in genetically-determined epilepsies, it is often unclear whether a neuropathological feature is causally related to seizure activity or is a secondary effect. We illustrate these two possibilities, using two genetic mouse 'knockout' models - p35-/-and Kv1.1-/-. In p35-/-mice, the gene deletion causes an abnormal pattern of brain development; this primary structural dysplasia in turn produces electrical and behavioral seizures. In Kv1.1-/-mice, the gene deletion is directly responsible for neuronal hyperexcitability and epilepsy, and neuropathological features appear secondarily as a result of intense recurrent seizure activity. Understanding the distinction between these two structure-function relationships is particularly important as we consider the development of novel therapies and points of intervention during epileptogenesis.
