Convulsiones - Espasmos infantiles

If your baby is having sudden - repeated movements, a head bob, a body crunch, a moment of stiffening - it's natural to feel scared, and you're not alone. These episodes, called infantile spasms, are a form of epilepsy that usually begins between 2 and 12 months of age. They can be easy to miss at first, sometimes looking like just a startle or a brief stare, but they tend to happen in clusters, often right after waking. The most important thing to know: acting quickly matters. Reaching out to your pediatrician right away and getting an early diagnosis gives your child the best chance at a good outcome.

What do infantile spasms look like?


Typical Spasm Cluster

Eyes widen, arms lift, and the infant pauses—movements repeat every few seconds in a short series.


Asymmetrical Spasms

Movements are stronger on one side of the body, suggesting a possible focal point in the brain.


Before Treatment

Symmetrical spasms occur in repeated clusters before medical therapy begins.


After Treatment

Spasms become focal and less symmetrical, demonstrating how therapy can change seizure presentation.


Spasms with Crying

A cluster of spasms accompanied by crying, followed by calm—showing how emotional changes can be part of the episode.
