What are infantile spasms

Infantile spasms (IS) are a rare seizure type that produce brief, sudden body spasms, which occur in clusters and are associated with developmental delays, making effective treatment during a critical window of a child’s development imperative. The possible benefit of treatment with VIGADRONE® is reducing spasm frequency in infants with IS. VIGADRONE® therapy has not been proven to improve an infant’s development.

Sometimes, the cause of IS is unknown. IS can be caused by different conditions, such as tuberous sclerosis complex. Additional information about IS is available online.
