title: Epilepsy in early development: the lesson from surgery for early intractable seizures.
abstract: This report examines the impact on development and the problems involved in assessing development in very young children with early-onset intractable seizures, particularly infantile spasms. A review of studies on medically and surgically treated children with infantile spasms underscores the relationship between seizure control and developmental outcome. About 50% of children with markedly intractable infantile spasms attained seizure control and significant improvement in the use of nonverbal communication, a developmental measure that has been used in other populations of developmentally delayed children. With the exception of duration of illness, clinical measures of age of onset of infantile spasms, type of surgery, and side of surgery did not appear to be related to the postoperative change in nonverbal communication. The neuropathology findings of surgically treated children with infantile spasms suggest that the underlying pathology occurs early in brain development. In conclusion, the cumulative effect of uncontrolled seizures and the underlying pathology might impact the early development of children with intractable infantile spasms.
