The main epileptic syndromes occurring during brain maturation, i.e. d
uring the neonatal period, infancy, childhood and adolescence, are rev

and helps the physician to select appropriate modes of investigation,
to predict the outcome and to choose the treatment of first choice. A
delineation of epilepsies based on physiopathologic mechanisms and on
etiology remains the ultimate goal.
