Approximately a third of children with West syndrome may develop recurrent epileptic seizures as they age. The syndrome often develops into the Lennox-Gastaut syndrome with mixed types of seizures that are difficult to control and is associated with intellectual disability.

Approximately another third of children with West syndrome will continue to have epileptic spasms at an older age group.

The last third to quarter of patients will have spasms that resolve with time, usually in patients who have no clear etiology.
