What is the outlook for Infantile Spasms ?
The prognosis for children with IS is dependent on the underlying causes of the seizures. The intellectual prognosis for children with IS is generally poor because many babies with IS have neurological impairment prior to the onset of spasms. Epileptic spasms usually reduce in number by mid-childhood, but more than half of the children with IS will develop other types of seizures. There appears to be a close relationship between IS and Lennox-Gastaut Syndrome, an epileptic disorder of later childhood.
