PURPOSE: We reviewed retrospectively our experiences with children with intractable epilepsy who were indicated for a modified Atkins diet (MAD).
METHODS: Twenty children (8 female, 12 male) who were aged 2-17 years with intractable epilepsy and tried the MAD between September 2008 and December 2010 were enrolled. Outcome measures included seizure frequency, adverse reactions and tolerability of the diet.
RESULTS: Finally 9 patients maintained the MAD with favorable seizure outcomes (a reduction of seizure frequency by over 50%) or successfully completed the diet therapy. Two patients who required a long-term trial of the diet therapy respectively due to Leigh's syndrome and uncategorized mitochondrial cytopathy derived from cytochrome c oxidase defect, respectively, successfully maintained the diet treatment without any significant complications. In 7 patients, the ketogenic diet (KD) was not only effective but also too restrictive or caused serious unwanted events. Five of them maintained the seizure outcome previously achieved by the KD with the MAD. Ten patients began the MAD because they were reluctant to start the KD. Unfortunately, only 2 patients maintained the MAD with favorable seizure outcomes. One patient who chose the MAD to bridge the KD and complete discontinuation of the treatment successfully completed the diet therapy.
CONCLUSION: A long-term treatment with the MAD was well tolerated. Moreover, the MAD can successfully substitute the classic KD in patients who showed improvement in seizure outcomes by the KD but could not tolerate it.
