Treatment of infantile spasms.
Infantile spasms are associated with a diverse range of conditions, and treatment options are available. However, outcomes remain generally poor, particularly for those with symptomatic etiologies. First-line therapy is considered to be hormonal (adrenocorticotropic hormone; ACTH), which some evidence suggests is more effective when started early. However, side effects may place limits on its use acutely and long-term. There is additional evidence for vigabatrin, specifically for infantile spasms secondary to tuberous sclerosis complex. In refractory cases, candidacy for surgical management should be explored, along with new-generation anticonvulsants (eg, topiramate, zonisamide) and the ketogenic diet. There is urgent need for further treatment trials comparing anticonvulsants with ACTH and a satisfactory animal model for the study of spasms.
