What Are the Three Main Causes of Autism?

Autism Spectrum Disorder (ASD) is a complex condition, and families often ask what causes it. While there isn’t a single answer, research highlights three main contributing factors:


Genetics
Autism
often runs in families. Specific genetic variations and mutations can influence brain development, making genetics one of the strongest predictors of ASD.


Environmental Influences
Factors during pregnancy and birth such as maternal health, exposure to certain medications, or complications, may increase the
likelihood of autism. These influences don’t directly cause autism but can interact with genetic predispositions.


Neurological Development
Differences in brain structure and connectivity affect how individuals with autism process information, communicate, and interact socially. These neurological variations are key to understanding ASD.

It’s important to note that autism is not caused by parenting style or personal choices. Each child’s experience is unique, shaped by a mix of these factors.
