General Discussion

West Syndrome is a rare form of infantile spasm that occurs very early in the development of an infant. Unusual brain wave patterns occur (hypsarrhythmia) and possibly mental retardation. The spasms that occur may range from violent jackknife or "salaam" movements where the whole body bends in half, or they may be no more than a mild twitching of the nose or mouth. These spasms usually begin in the early months after birth and can often be helped with medication. There may be many different causes for the spasms. Neurological testing will be helpful in determining the cause.
