[Relationship between vitamin D and autism spectrum disorder]

Area of Science:

• Neuroscience
• Developmental Biology
• Nutritional Science

Context:

• Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with known genetic and environmental influences.
• Emerging research investigates the role of environmental factors, including vitamin D, in ASD etiology.
• Vitamin D plays a critical role in brain development and function.

Purpose:

• To explore the potential link between vitamin D deficiency and autism spectrum disorder.
• To investigate vitamin D serum levels in children diagnosed with ASD compared to neurotypical children.

Summary:

• Vitamin D is essential for brain homeostasis, neurodevelopment, and immune function.
• Studies show significantly lower serum 25-hydroxy vitamin D levels in children with ASD.
• Vitamin D deficiency during critical developmental periods (pregnancy, early childhood) may act as an environmental trigger for ASD.

Impact:

• Highlights vitamin D deficiency as a potential modifiable environmental risk factor for ASD.
• Suggests the importance of monitoring and ensuring adequate vitamin D levels during pregnancy and early childhood.
• Opens avenues for further research into vitamin D supplementation and ASD prevention/intervention strategies.
