Exploring the intersection of the microbiome and the developing brain: Impacts on schizophrenia risk

Area of Science:

• Microbiome research
• Neurodevelopment
• Perinatal health

Background:

• The perinatal period is critical for both microbiome and brain development.
• Disruptions in early life microbial communities are linked to neurodevelopmental disorders.
• Schizophrenia and psychosis risk are associated with perinatal neurodevelopmental alterations.

Purpose of the Study:

• To review the interplay between the developing microbiome and brain.
• To explore the microbiome's role in perinatal neurodevelopment and schizophrenia risk.
• To identify strategies for mothers to mitigate offspring schizophrenia risk.

Main Methods:

• Literature review of microbiome and neurodevelopment studies.
• Analysis of the perinatal window's significance.
• Synthesis of current understanding on microbiome-schizophrenia links.

Main Results:

• The maternal and infant microbiome profoundly influences brain development.
• Perinatal microbiome composition is a key factor in neurodevelopmental trajectories.
• Specific microbial exposures or disruptions may increase schizophrenia risk.

Conclusions:

• The perinatal microbiome is a critical target for understanding and potentially preventing schizophrenia.
• Maternal and infant gut health during pregnancy and early life is crucial for brain health.
• Interventions aimed at optimizing the perinatal microbiome may reduce offspring schizophrenia risk.
