What Causes Autism?
Autism is a syndrome, or condition, with many possible causes. Anything that makes the central nervous system (CNS) develop abnormally can cause autism. The CNS functions as a computer for the body. Messages from the CNS control all aspects of learning, thinking, and movement that allow us to learn about and function in the world.
Any interruption or change in the early development of the system will affect continuing development of the system and result in a developmental disability. The event that initially triggers these developmental differences could happen during fetal development, during birth, or after birth. It is not always possible to identify the exact causes of the damage.


Important things to know!
- Autism and other neurobiological conditions are NOT caused by lack of love or parenting skills
- Anything that affects the functioning of the central nervous system can trigger the symptoms of autism.
- Knowing the causes matters for medical research and for helping families get the right genetic and medical guidance they deserve.
*Note: Parents should know that early intervention and effective educational programs do not depend on finding the exact cause. The most important thing is getting the right support early on!
