No generalizations can be made about this issue. In most cases, developmental delays and epilepsy are the result of congenital or acquired brain disorders and are two parts of the same condition. Of course, if your child has frequent and severe seizures, his or her development may also be delayed. This is because excessive abnormal electrical activity is constantly impeding normal brain function, and frequent seizures do not cause hypoxia and damage to the brain. Therefore, early control of discharges and seizures is especially important. A significant proportion of children can improve developmentally and only after the seizures have resolved.
