Spasms happen on their own,
not as a reaction to something

Spasms might look like sudden, brief stiffening of the muscles

  • The infant may bend forward or arch the back during an episode
  • Legs may curl up to their stomach
  • The baby may cry during or after

Spasms can be subtle and easily missed

  • Spasms be confused with startle, reflux, or colic
  • Small movements—forward crunch of the body, outward movement of the arms
  • Arms may fling out over their head and legs extend
  • Can be as simple as a head bob
  • Eyes may look up and back with the spasm or stare off to the side

Each spasm lasts only 1-2 seconds

  • They occur mainly when the baby wakes up in the morning or after a nap
  • Sometimes, episodes can happen before falling asleep

Spasms occur in repetitions, called “clusters”

  • Clusters mean that several spasms might happen one after another
  • A spasm will repeat every 15 seconds or so, forming a cluster
  • A cluster can be 10, 20, 30, or even more spasms over several minutes
  • These clusters can occur many times a day
Act today if you see movements that look like infantile spasms.

Every day without treatment means a greater chance of mental and physical developmental disabilities.

React right away

Witnessing the
symptoms can take time
and careful observation.


If your baby is exhibiting these types of spastic/jerking movements, please head directly to the ER and demand an EEG. Take video if you can and be prepared to be [firm] to be taken seriously. This is a very rare form of epilepsy, but it is catastrophic and considered a neurological emergency! Early and aggressive treatment is necessary to limit/prevent irreversible
brain damage.”

EEG=electroencephalogram; ER=emergency room.

Become familiar with what infantile spasms can look like. Remember, infantile spasms can be very different from one baby to another. Be on alert for the subtleties of some spasms. If you are suspicious that your child’s movement may be a spasm, get your baby checked today.
