Autism Spectrum Disorder (ASD) does not have a single cause. Instead, research shows that autism develops from a combination of factors that influence brain development. The three main causes often linked to autism are:
- Genetics – Family history plays a significant role. Certain genetic differences or mutations can increase the likelihood of autism. Studies show that if one child in a family is diagnosed, siblings may have a higher chance of being on the spectrum as well.
- Brain Development – Differences in how the brain grows and connects can affect communication, behavior, and social interaction. Early brain development plays a critical role in shaping these outcomes.
- Environmental Factors – While the environment alone doesn’t cause autism, certain factors such as prenatal exposure to toxins, complications during birth, or advanced parental age may contribute when combined with genetic predisposition.
It’s important to note that parenting styles or personal choices do not cause autism. Understanding these root factors helps families focus on support rather than blame.
