Article Excerpts About Symptoms of Infantile Spasms:

Characteristic features of IS, sometimes called West syndrome, include myoclonic seizures, hypsarrhythmia (abnormal, chaotic electroencephalogram), and mental retardation. The spasms are described as sudden, brief contractions of one or more muscle groups, and may be followed by a longer (less than 10 seconds) tonic phase. Most often the spasms occur in clusters during which the intensity or the frequency of the spasms may increase progressively to a peak, decline, or cease. The clusters tend to occur soon after arousal from sleep. They are not a feature of falling asleep. The spasms usually involve the muscles of the neck, trunk, and extremities. The intensity of the contraction and the number of muscle groups involved varies in different attacks and from infant to infant. Neurological abnormalities other than seizures and retardation--such as cerebral atrophy, congenital abnormalities and hydrocephalus--are commonly reported among patients with IS.
