Maternal obesity and neurodevelopmental and psychiatric disorders in offspring

Area of Science:

• Neuroscience
• Developmental Biology
• Public Health

Background:

• Maternal obesity and high-fat diet intake are increasingly linked to adverse neurodevelopmental outcomes in offspring.
• Human and animal studies suggest a correlation between prenatal/lactational exposure and disorders like autism, ADHD, and schizophrenia.

Purpose of the Study:

• To synthesize existing human and animal data on the effects of maternal obesity and high-fat diets on fetal brain development.
• To identify key biological mechanisms underlying these neurodevelopmental and psychiatric risks.
• To review potential therapeutic strategies to mitigate these adverse effects.

Main Methods:

• Comprehensive literature review of human epidemiologic and animal studies.
• Synthesis of data linking maternal obesity and diet to offspring neurodevelopmental and psychiatric conditions.
• Analysis of proposed underlying biological mechanisms.

Main Results:

• Prenatal and lactational exposure to maternal obesity and high-fat diets are associated with a spectrum of neurodevelopmental and psychiatric disorders in offspring.
• Key implicated mechanisms include neuroinflammation, oxidative stress, disrupted metabolic and neurotransmitter signaling, and altered synaptic plasticity.
• Evidence suggests a significant impact on fetal brain development and subsequent offspring mental health.

Conclusions:

• Maternal obesity and high-fat diets pose significant risks to fetal neurodevelopment and offspring mental health.
• Understanding the underlying mechanisms is crucial for developing effective interventions.
• Further research into therapeutic approaches is warranted to protect against these detrimental effects.
