简要总结
The purpose of this study is to determine stool microbiome composition and biomarkers that are differentially abundant and those that are associated with response to treatment (eg, anticonvulsant drugs).
详细描述
Recent research suggests that the intestinal microbiota plays a central role in human health, and may play a role in a variety of central nervous system disorders, including seizure susceptibility. The microbiota has been shown to be associated with changes in factors relevant to neurotransmission, including neurotransmitter signaling, synaptic protein expression, long-term potentiation, and myelination. In addition to the microbiota's potential role in general neurotransmission, research suggests that the gut microbiome may differ between patients with pharmaco resistant and pharmaco-sensitive epilepsies. In support of this idea, ketogenic diet has been used as an alternative treatment for those with pharmaco-resistant epilepsy and there are indications of possible direct interactions of anti-epileptic drugs (AEDs) with the intestinal microbiota.
