Infantile Spasms

Infantile spasms are a serious type of seizure typically occurring during infancy, usually with onset between five and nine months. The seizures may be identified by a sudden jerking of the body, in which the child flexes or extends at the trunk. The indication may also be more subtle, such as staring or blinking. Infantile spasms commonly appear in clusters, typically occurring as the child is going to sleep, or soon after waking. (For video examples of infantile spasms, see Jacob's family story.)
