Autism Spectrum Disorder from the Womb to Adulthood: Suggestions for a Paradigm Shift

Area of Science:

• Neurodevelopmental Disorders
• Genetics and Epigenetics
• Immunology and Gut Microbiome

Background:

• Autism Spectrum Disorder (ASD) presents diverse needs, challenging global healthcare.
• Traditional genetic models fail to explain ASD epidemiology and clinical features.
• A holistic paradigm integrating genetics, environment, and epigenetics is necessary.

Purpose of the Study:

• To propose a comprehensive pathogenetic paradigm for Autism Spectrum Disorder (ASD).
• To identify effective primary prevention strategies for ASD.
• To guide a personalized, dynamic, systemic, and interdisciplinary healthcare approach for ASD.

Main Methods:

• Review and synthesis of current research on ASD pathogenesis.
• Focus on the interplay between immune activation, gut dysbiosis, and mitochondrial dysfunction/oxidative stress.
• Emphasis on the critical neurodevelopmental window of the 'First 1000 Days'.

Main Results:

• The 'First 1000 Days' are crucial for neurodevelopment, significantly impacted by environmental factors.
• A vicious loop involving immune activation, gut dysbiosis, and oxidative stress is implicated in ASD.
• Early intervention targeting these molecular pathways is key for effective prevention.

Conclusions:

• A paradigm shift towards a dynamic, multi-factorial understanding of ASD is essential.
• Primary prevention during pregnancy and early life offers the most promising intervention strategy.
• A systemic, interdisciplinary approach is required for comprehensive ASD care from womb to adulthood.
