An unusual type of recurrent seizure, also called progressive myoclonic encephalopathy or salaam attacks, that affect babies. The condition is a type of epilepsy and initially occurs around four to nine months of age.
Spasms can arise hundreds of times a day, each lasting a few seconds. During a seizure, the baby’s head without warning falls forwards, the limbs bend, the body stiffens, then the arms and hands extend and move outwards. These seizures are often a sign of severe brain damage; affected babies usually have serious developmental delay.
