Rare Diseases. West syndrome is a form of seizure disorder (epilepsy) that begins in infancy. A specific type of seizure called infantile spasm is part of this syndrome, as are abnormal brain wave patterns called hypsarrhythmia, and mental retardation. Almost any condition that can cause brain damage can cause West syndrome. The two most common causes are tuberous sclerosis and lack of oxygen during birth.
