CNS overstimulation can be caused by several factors. One common cause is the ingestion of stimulant drugs such as amphetamines or cocaine, which increase the levels of neurotransmitters like dopamine and norepinephrine in the brain. Exposure to pesticides and certain industrial chemicals can also lead to CNS overstimulation. Additionally, some natural toxins, like those found in certain plants and animals, may trigger similar effects.
