Treatment
Shorter duration between the onset of IS and initiation of standard treatment appears to lead to an improved outcome; therefore early recognition of the seizures and early treatment are essential. [childneurologyfoundation.org]

Treatment of vitamin B 6 toxicity is to stop taking vitamin B 6. Recovery is slow and, for some patients, incomplete. [merckmanuals.com]
Prognosis
Prognosis The prognosis for children with IS is largely dependent on the underlying cause. The intellectual prognosis for children with IS is generally poor because many babies with IS have neurological impairment prior to the onset of spasms. [childneurologyfoundation.org]
The prognosis for idiopathic infantile spasms tends to be better than for symptomatic infantile spasms [ 10 ]. [patient.info]
