[Abstract]
BACKGROUND: The ketogenic diet is a non-pharmacologic treatment option for children with drug-resistant epilepsy. This systematic review and meta-analysis aimed to assess the efficacy of the ketogenic diet on seizures frequency in children.

METHODS: We reviewed the literature using Cochrane, EMBASE, MEDLINE, and highly qualified journals.Randomized controlled trials were chosen to investigate the seizures-free regime or at least 50% seizures reduction after three months from the starting of the ketogenic diet or earlier. We have selected articles from January 2011 to January 2020.Eight articles were eligible. The data show a significant reduction in seizure frequency in the dietary treatment pediatric population. The rate of a seizures-free regime or at least 50% seizures reduction was 48.31% of patients in the intervention group.

RESULTS: Our overall meta-analysis underlined the significant efficacy. The KD group is 5.6 times more likely than the control group to have a 50% reduction of seizures after three months of the diet or earlier.QUADAS and AMSTAR assessments showed a low risk of bias and adequate accuracy.

CONCLUSION: The results show that the KD reduces seizure frequency in children with drug-refractory epilepsy. KD is an effective treatment option for children and adolescents with refractory epilepsy.
