General Discussion

West syndrome is a constellation of symptoms characterized by epileptic/infantile spasms, abnormal brain wave patterns called hypsarrhythmia and intellectual disability. 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 shoulder or eye changes. These spasms usually begin in the early months after birth and can sometimes be helped with medication. They can also occur rarely in older patients; if this happens, they are called "epileptic spasms" rather than infantile spasms. Currently, the International League Against Epilepsy (ILAE) has revised the terminology and epileptic spasms is now preferentially used to encompass the different age groups of onset. There are many different causes of epileptic spasms and if a specific cause can be identified, a diagnosis of symptomatic epileptic spasms can be made. If a cause cannot be determined, a diagnosis of cryptogenic epileptic spasms is made.
