A ketogenic diet delivered through a feeding tube stopped seizures and improved nutrition in one infant with Miller-Dieker syndrome, a rare genetic disorder causing severe brain development problems and drug-resistant epilepsy. The diet was well tolerated for several months, suggesting this approach may help children with this condition who cannot eat normally. However, this finding comes from a single case report, so more research is needed.
Miller-Dieker syndrome is a rare genetic condition that causes severe brain development problems and seizures that don’t respond to medications. Children with this condition often struggle to eat and are at risk for serious lung infections. According to Gram Research analysis, doctors successfully used a special high-fat, low-carb diet delivered through a feeding tube to help one infant with this condition stop having seizures and improve their nutrition. This case shows that the ketogenic diet, delivered directly into the small intestine through a tube, may be a helpful treatment option for children with this rare disorder who can’t eat normally.
Key Statistics
A 2026 case report published in Case Reports in Pediatrics documented one infant with Miller-Dieker syndrome who achieved seizure freedom after starting a ketogenic diet delivered through a feeding tube directly into the small intestine.
The ketogenic diet with a low ratio of 1.25:1 was well tolerated in the infant with Miller-Dieker syndrome and maintained seizure control for several months while also improving nutritional status.
The case demonstrates that enteral ketogenic diet therapy, delivered through a feeding tube into the small intestine, is feasible for managing drug-resistant epilepsy in children with severe neurological impairment who have feeding difficulties.
The Quick Take
- What they studied: Whether a special high-fat, low-carb diet given through a feeding tube could help stop seizures and improve feeding in a baby with Miller-Dieker syndrome, a rare genetic disorder.
- Who participated: One infant diagnosed with Miller-Dieker syndrome who had seizures that didn’t respond to medications and severe difficulty eating.
- Key finding: The ketogenic diet delivered through a feeding tube into the small intestine stopped the child’s seizures, improved their nutrition, and was well tolerated for several months.
- What it means for you: For families dealing with Miller-Dieker syndrome and drug-resistant seizures, this case suggests the ketogenic diet delivered through a feeding tube may be worth discussing with doctors. However, this is based on one child’s experience, so more research is needed before making treatment decisions.
The Research Details
This research is a case report, which means doctors documented the medical history and treatment of one specific patient. The infant had Miller-Dieker syndrome, a rare genetic condition affecting brain development, along with seizures that didn’t stop with medication and serious feeding problems. The doctors started the ketogenic diet, a special eating plan high in fats and low in carbohydrates, but delivered it through a feeding tube instead of regular food. They placed the tube directly into the small intestine to bypass the stomach, which helped the child tolerate the diet better. The doctors used a low ketogenic ratio of 1.25:1, meaning the diet had less fat compared to other versions of this diet.
Case reports are important for rare diseases like Miller-Dieker syndrome because large research studies are difficult to conduct when very few people have the condition. This case report shows that the ketogenic diet can be safely delivered through a feeding tube in a way that works for children who can’t eat normally. It provides doctors with practical information about how to manage both seizures and feeding problems in children with severe neurological conditions.
This is a single case report, which is the lowest level of research evidence. It shows what happened in one child but cannot prove the diet works for all children with Miller-Dieker syndrome. The case is valuable because it documents a real patient’s experience and provides doctors with practical guidance, but more research with multiple patients would be needed to confirm these results apply broadly.
What the Results Show
The infant experienced seizure freedom, meaning the seizures stopped completely, after starting the ketogenic diet through the feeding tube. This improvement was maintained for several months while the child was on the diet. The child’s nutritional status improved, meaning they were getting better nutrition and gaining weight appropriately. The diet was well tolerated, which means the child’s stomach and digestive system handled the special diet without major problems like vomiting or diarrhea. The doctors used a low ketogenic ratio of 1.25:1, which is less restrictive than standard ketogenic diets, suggesting that even a milder version of this diet may help.
Beyond seizure control, the ketogenic diet appeared to help stabilize the child’s overall condition for several months. The feeding tube placed directly into the small intestine (called a jejunostomy) proved to be a practical way to deliver the diet in a child with severe feeding difficulties. The case demonstrates that a multidisciplinary approach, involving different medical specialists working together, is important for managing complex cases like Miller-Dieker syndrome.
The ketogenic diet is already known to help some children with drug-resistant epilepsy, but most research focuses on children who can eat regular food or drink formula. This case is notable because it shows the diet can work in children with severe neurological impairment who require feeding tubes. Previous research on ketogenic diet for rare genetic disorders is very limited, making this case an important addition to the medical literature.
This is a single case report involving only one child, so the results cannot be generalized to all children with Miller-Dieker syndrome. The child died from an unrelated surgical complication (volvulus, a twisted intestine), so we don’t know how long the benefits would have lasted. The case doesn’t include a comparison group, so we can’t be certain the diet alone caused the improvement rather than other treatments or natural variation. More research with multiple patients is needed to confirm these findings.
The Bottom Line
For families with children who have Miller-Dieker syndrome and drug-resistant seizures, discuss the ketogenic diet delivered through a feeding tube with your medical team. This case suggests it may be worth trying as part of a comprehensive treatment plan. The evidence is based on one child’s experience, so expectations should be realistic. Work with a multidisciplinary team including neurologists, nutritionists, and gastroenterologists.
This research is most relevant to families with children diagnosed with Miller-Dieker syndrome who have seizures that don’t respond to medications and feeding difficulties. Pediatric neurologists and gastroenterologists managing rare genetic disorders should be aware of this case. Children with other severe neurological conditions requiring feeding tubes may also benefit from discussing this approach with their doctors.
In this case, seizure freedom was achieved and maintained for several months on the ketogenic diet. However, individual responses vary, and it may take time to adjust the diet and feeding tube setup. Families should expect ongoing monitoring and adjustments with their medical team.
Frequently Asked Questions
