Abstract
The disorder of the automatic spectrum is a neurodolevating disorder characterized by a decrease in social interactions, communication and stereotypical disorders and repeated behaviors with various degrees of gravity. A number of systematic reviews and meta-analyses have described prenatal and perinatal factors, as well as factors related to maternal nutrition and lifestyle. There is evidence to support the importance of vitamin D in the normal structure and function of the nervous system. The effects of VD administration during pregnancy on the mother and conception before and after birth have been repeatedly investigated. It has been found that preventing VD can reduce the risk of autism.
