The Human Gut Microbiome as a Potential Factor in Autism Spectrum Disorder

Area of Science:

• Neuroscience
• Microbiology
• Gastroenterology

Background:

• Gastrointestinal disorders are common in autism spectrum disorder (ASD).
• Gut microbial dysbiosis is frequently observed in ASD patients.
• The link between gut microbiota and ASD pathogenesis is under investigation.

Purpose of the Study:

• To review the role of the microbiota-gut-brain axis in autism.
• To examine how gut dysbiosis impacts gut permeability, immune function, and microbial metabolites in ASD.
• To discuss the potential role of the gut microbiome in epigenetic modifications and ASD severity.

Main Methods:

• Literature review of studies on the gut microbiome and ASD.
• Analysis of the impact of gut dysbiosis on physiological and neurological functions.
• Summary of current microbiota-targeted therapies for ASD.

Main Results:

• Gut microbiota dysbiosis may influence gut permeability, immune responses, and metabolite production in individuals with ASD.
• The gut microbiome might play a role in epigenetic modifications, potentially affecting ASD severity.
• Emerging therapies targeting the gut microbiota show promise for ASD symptom management.

Conclusions:

• The microbiota-gut-brain axis is a significant area of research for understanding ASD.
• Microbiota-targeted therapies offer potential for reducing and treating ASD-related symptoms.
• Further large-scale, well-designed studies are needed to confirm these findings and therapeutic efficacy.
