Participant Flow

Study participants were recruited via advertisement at the pediatric outpatient department, Srinagarind hospital, Faculty of Medicine, Khon Kaen University, Thailand. A total of 22 patients with Lennox-Gastaut Syndrome (LGS) were enrolled between August 2010 and December 2013

All patients were assigned to record sizure frequency prior to start the protocol
