Potential causes for autism seem to creep up all of the time. While some tend to be more farfetched than others, the latest supports the medical belief that a combination of genetics and environmental factors influence the development of autism long before a child is born.
The researchers at Columbia University's Mailman School of Public Health reveal any time a pregnant woman's immune system is triggered to respond to an illness or infection – such as through a fever – it can disrupt the brain development of the fetus. This, in turn, can result in the development of autism long before the baby is born.
This connection has never been proven and the timing is merely coincidence. Typically, autism symptoms are a little unclear until a child is around the age of two. This is around the time where parents will usually start to notice their child's struggle with speech and social interactions. The reason the timing is a coincidence is because this is the same age where a child is due for a few different vaccines.
