Vitamin D Deficiency and Autism Spectrum Disorder

Area of Science:

• Neuroscience
• Developmental Biology
• Endocrinology

Background:

• Vitamin D acts as a neurosteroid hormone vital for neurodevelopment.
• Mechanisms include neural cell proliferation, neurotransmission, and immune function in the Central Nervous System.
• Deficiency during critical developmental periods may lead to adverse neuropsychological outcomes like Autism Spectrum Disorder (ASD).

Purpose of the Study:

• To review the literature on the role of prenatal and early postnatal vitamin D deficiency in ASD etiopathogenesis.
• To explore the potential impact at both genetic and environmental levels.
• To evaluate the efficacy of vitamin D supplementation in children with ASD.

Main Methods:

• Comprehensive literature review of existing studies.
• Analysis of genetic and environmental factors related to vitamin D and ASD.
• Examination of research on vitamin D supplementation in autistic children.

Main Results:

• Evidence suggests a significant association between vitamin D deficiency and ASD.
• Vitamin D deficiency is observed in children with ASD and in mothers whose children develop ASD.
• Results regarding the efficacy of vitamin D supplementation are conflicting yet promising.

Conclusions:

• Prenatal and early postnatal vitamin D deficiency may be a contributing risk factor in ASD.
• Further Randomized Controlled Trials during pregnancy and early infancy are essential.
• Understanding vitamin D's role could inform future interventions for ASD.
