Genes and biological processes are both involved in the development and the core features of autism. Research shows that genes play a significant role in autism. Researchers have discovered that several genes work together in the development autism. Some of the key genes have been identified for certain types of autism; however, more research is needed to determine the exact genes that trigger each type of autism.
Our brains go through a process called synaptic pruning. This process eliminates extra neurons and synaptic connections in the brain. In children with autism, the process does not prune as many neural connections. Because of this, brains of autistic children are over developed and have too many connections and pathways to work efficiently.

Studies on twins show that if one twin has autism the likely hood that the other twin will have it is over seventy percent. Showing us that autism is actually hereditary.
An autistic child’s brain is physically different when compared to a child without autism. Research has shown that certain regions of the brain are smaller in children with autism. The corpus callosum is a bundle of neural fibers that connect the two hemispheres of our brain, allowing each side to communicate with the other. In autistic children, this area is smaller. In return, this makes their functional abilities abnormal and metabolic abilities abnormal.
It is worth noting there is no proven evidence that environmental factors such as vaccines and certain types of food affect a child with autism in any way. Genes and biological processes are the number one reason children develop autism. There are also many psychological factors and social factors that can contribute to the development of autism and how it will run its
