title: Epilepsy characteristics and psychosocial factors associated with ketogenic diet success.
abstract: The ketogenic diet is an effective therapy for childhood epilepsy, but its important impacts on families could affect successful treatment. We assessed medical and psychosocial factors associated with successful ketogenic diet treatment. A total of 23 families of patients treated with ketogenic diet completed questionnaires (30% response), including inquiries about challenges to successful dietary treatments and validated family functioning scales. Of these, 14 were considered successful (diet discontinued once the child was seizure-free or continued as clinically indicated). Family-identified challenges were food preparation time (n = 11) and that the diet was too restrictive (n = 9). Neither Medicaid insurance nor family functioning scale scores were significantly associated with successful treatment. Lower seizure frequency prior to ketogenic diet initiation (P = .02) and postdiet seizure improvement (P = .01) were associated with increased odds of success. Effective ketogenic diet treatment is dictated both by psychosocial and epilepsy-related influences. A focus on understanding the psychosocial issues may help to improve families' experiences and success with the ketogenic diet.
