Infantile spasms syndrome in monozygotic twins. A 7-year follow-up.

The Infantile Spasms Syndrome is a fairly common form of seizures in infancy. Many papers and several books have been published on this syndrome but several aspects are still obscure. In particular, there is some controversy about anticonvulsant treatments and on the question of improvements in mental status. An unusual case of 2 monozygotic twins with by this syndrome, both with clinical manifestations appearing within a few hours on the same day, at 6 months has been followed up for 7 years, giving us the opportunity to understand some aspects of the clinical course of the disease and long term treatment.
