Speech, social interaction, cognitive skills, and many other abilities are located in different areas of the central brain. As a result of widespread neuroinflammation observed in the brain, both oxidative stress and nitrosamide stress pathways are activated. As a result of oxidative stress activation, there is an increase in two important products; 1. Free radicals 2. Reactive Oxygen Species (ROS). Both free radicals and reactive oxygen species act like chemical toxins, resulting in numerous damages and disruptions in the cellular structures and functions of nerve cells in the brain. The balance in the excitation systems of neurons is disrupted, which is directly related to the behavioral disorders observed in autism.
