What Rise Risk Factors and Causes Are There for Autism?

 ASD's precise causes are not yet fully understood. Potential causes could be biological and environmental: 

 

Based on information gathered from five nations, it was shown that 80% of ASD cases are hereditary. It implies that either the mother or the father may have contributed to the development of ASD through inherited genetic effects. 

 

-According to a study of 277 twin pairs, having an ASD sibling increases your likelihood of developing the disorder. 

 

-The findings of a study involving 10 US study sites show that older parents are more likely to have ASD. 

 

-ASD risk was greater in pregnant women who used the prescription medicines thalidomide and valproic acid. 

 

-According to a different study, ASD development could happen before, during, or after birth. 

 

-ASD is more likely to occur in preterm children. 

 

-ASD is highly prevalent in kids with Down syndrome. ASD is also associated with chromosomal abnormalities such as Fragile X syndrome and tuberous sclerosis. 

 

-ASD is linked to environmental pollution, particularly nitrogen dioxide (NO2) exposure. NO2 is produced when fossil fuels like coal, oil, or gas are burned in motor vehicles. Researchers discovered a connection between ASD and mothers' exposure to NO2 during pregnancy and the first year of a child's life. 

 

-The gut-brain axis is related to ASD. According to a study, gene mutations that cause autism affect how neurons communicate with one another in the brain. This mutation also affects the stomach.
