Abstract

Autism Spectrum
Disorder (ASD) is a severe neuro-developmental disorder which generally starts
during infancy as well as mostly in the first 3 years of life. ASD is
characterized by social, behavioral, and communication symptoms. Genetics and certain environmental
factors may play a role in the pathogenesis of autism, although the etiology of
the disease is unknown. Maternal nutrition is important for development of the
fetal brain. The mother’s nutritional condition before and during pregnancy may
affect the risk of ASD incidence. Vitamin D
deficiency is taken into consideration as a possible risk factor for
development of ASD. Compared to healthy peers, children with ASD were indicated
to have lower levels of vitamin D. However, it is not clear yet if this condition
was influenced by the fact that whether patients with ASD are born with lower
levels of vitamin D or they are exposed to sunlight lesser. Also folic
acid supplementation during pregnancy and blood folate levels in children with
autism are environmental factors contributing to autism incidence through
dietary intake. The aim of this study is to
explain the relationship between vitamin D, folic acid and ASD.
