Probiotics May Help Reduce Seizures In Some Children

What was studied

This study investigated whether a daily probiotic might help children with medication-resistant epilepsy, meaning seizures were not effectively controlled by antiseizure medicines. It was a prospective, randomized, triple-blind clinical trial, meaning the children were assigned by chance to probiotic or placebo and masking was used during the study.

A total of 62 children treated at a major pediatric epilepsy referral center took part. Thirty-one children received probiotics each day, and 31 received a placebo. The researchers followed them at 45 days, 3 months, and 6 months. The main outcome was the number of seizures. They also looked at antiseizure medicine use, including dose and how often medicines were taken.

What they found

Compared with the placebo group, the probiotic group showed a statistically significant reduction in seizure frequency. In the probiotic group, 20 of 31 children (64.5%) had a decrease in seizure frequency, while 11 of 31 had no change.

The researchers also reported a statistically significant relationship between probiotic use and seizure frequency after starting probiotics in children whose neuroimaging was normal. For medicine use, probiotic administration had a statistically significant effect only on reducing the dose of phenobarbital.

Limits of the evidence

This was a small study from one center, with 62 children, so the results may not apply to all children with medication-resistant epilepsy. The abstract does not provide details such as the exact probiotic used, the size of seizure reduction in the placebo group, or side effects.

Importantly, the study itself says antiseizure medication changes were not protocolized, and some confounders were not fully controlled. That means the study cannot show for certain that probiotics directly caused the seizure reduction. It shows an association rather than firm proof of cause and effect.

For families and caregivers

This study suggests probiotics may be a possible add-on approach worth further study for some children with hard-to-control epilepsy. The trial found an association between probiotic use and fewer seizures.

Still, this is early evidence and not enough to show probiotics will help every child or to replace standard epilepsy care. Families may wish to discuss this with an epilepsy specialist, especially because the best probiotic type, dose, safety, and which children might benefit most are still unclear from the abstract.

What to watch next

Larger studies with clearer plans for antiseizure medicine adjustments and fuller reporting of safety, probiotic strains, and doses would help clarify these findings.

Terms in this summary

medication-resistant epilepsy

Epilepsy in which seizures are not effectively controlled with antiseizure medicines.

probiotic

A product containing live microorganisms that may affect the body, including gut health.

placebo

A look-alike treatment with no active ingredient, used for comparison in research.

randomized

Assigned by chance to different study groups to reduce bias.

triple-blind

A study design in which masking is used so key people involved in the trial do not know who received which treatment.

statistically significant

A result that is unlikely to be due to chance alone, based on the study's calculations.

phenobarbital

An antiseizure medicine used to help prevent seizures.

neuroimaging

Brain scans used to look at the brain's structure.
