Gut Microbiota Composition and Modulation in Developmental and Epileptic Encephalopathies

Area of Science:

• Microbiology
• Neurology
• Gastroenterology

Background:

• The gut microbiota (GM) plays a vital role in host health and communicates with the central nervous system (CNS) via the microbiome-gut-brain (MGB) axis.
• Pathological alterations in the GM are increasingly implicated in neurological disorders, including epilepsy.
• Research on GM's impact on developmental and epileptic encephalopathies (DEEs) is limited.

Purpose of the Study:

• To review current clinical and preclinical research on the relationship between GM composition and DEEs.
• To specifically examine the influence of GM on infantile epileptic spasms syndrome (IESS) and Dravet syndrome (DS).

Main Methods:

• Literature review of recent clinical and preclinical studies.
• Focus on studies investigating GM alterations in DEEs, IESS, and DS.

Main Results:

• Accumulating evidence suggests a connection between GM dysbiosis and the pathogenesis of DEEs.
• Specific studies highlight the role of GM composition in IESS and DS.

Conclusions:

• GM dysbiosis is a potential contributing factor to DEEs.
• Further research into the GM-DEE relationship is essential for developing novel therapeutic strategies targeting the GM to manage seizures.
