Recognize the Signs
Infantile Spasms
Repeated, brief movements in a baby may need urgent assessment, even when the baby seems well between episodes.
Seek assessment immediately.
Tell your baby’s healthcare provider you are concerned about infantile spasms. If immediate assessment is unavailable, go to an emergency department.
Call 911 for breathing problems, unresponsiveness or another emergency sign. Do not delay care to collect a video or wait for more episodes.

Possible signs
The body may suddenly bend, straighten or arch. Some events look like small head nods or body crunches. Spasms often repeat in clusters, sometimes around waking.
Developmental changes
Report reduced interaction or loss of skills. Spasms can occur without these changes, so their absence does not rule them out.
Prompt specialist care matters.
Assessment generally includes an urgent EEG. Early treatment is important for development. A safely recorded video may help, but seeking care comes first.
