Short- and long-term seizure-free outcomes of dietary treatment in infants according to etiology.

Purpose: It is important to determine whether specific etiology is more effective to dietary treatment so that the diet can be started earlier for infants. We evaluated etiology-specific, seizure-free outcomes of dietary treatment in infants <1 year of age.

Methods: We conducted a 10-year, retrospective, longitudinal observational study of 115 infants treated with ketogenic diet (KD) or modified Atkins diet (MAD).
