CNN:

Dravet Syndrome is a rare, severe form of intractable epilepsy. Intractable means the seizures are not controlled by medication. The first seizures with Dravet Syndrome usually start before the age of 1. In the second year, other seizures take hold: myoclonus, or involuntary, muscle spasms and status epilepticus, seizures that last more than 30 minutes or come in clusters, one after the other.
