What are Infantile Spasms?

Infantile spasms, also known as West syndrome, are a rare but serious type of epilepsy that typically begins in infants under 1 year old. They involve sudden, brief muscle contractions—often described as head nodding or jerking movements—that can occur in clusters. These seizures are often subtle but may signal significant underlying brain issues.

Early diagnosis and treatment are critical. Treatments may include corticosteroids like ACTH or vigabatrin, depending on the cause. The outlook varies: some children respond well to treatment and develop typically, while others may experience ongoing seizures or developmental delays, especially if treatment is delayed or if there’s an underlying neurological disorder.
