The Ketogenic Diet (KD) is a well-established treatment for epilepsy in children and adults. We describe our 10-year KD experience in children less than two years of age diagnosed with medically refractory epilepsy. We conducted a retrospective case-note review of infants managed with KD at our centre between 2006 and 2016. Twenty-nine children between 2½ weeks and 23 months of age were identified, with mixed epilepsy aetiologies. Ninety-three percent had daily seizures and 82% were on two or more anti-epilepsy drugs (AEDs) at the time of KD commencement. KD was continued for more than four weeks in 86%. Based on a combination of parental reports, hospital observations and seizure diaries, two of 29 became seizure free, seven demonstrated >50% seizure reduction, and eight showed a decrease in seizure intensity/frequency. No adverse effects were observed in 45% patients, and dietary therapy was stopped in only two because of poor tolerability. We conclude that KD can be utilised and is generally well tolerated in infants with severe epilepsies. In addition, our experience suggests efficacy with improved seizure frequency/severity in around 50% without adverse effects on developmental outcome.
