[Juvenile myoclonic epilepsy].

Since juvenile myoclonic epilepsy (EMJ) and/or Janz syndrome is a primary syndrome which persists throughout life, there should be permanent behavioural hygiene and treatment to keep it under control. Suspension of treatment is nearly always followed by recurrence. Although some researchers report relapses of 75% on suspension of treatment, Janz (1995), cited by Dreifuss points out that this rises to 91% in patients who suspend treatment after two years with no crises. This is, to date, the highest documented level of relapses in epilepsy (5,6,12).
