There is no single known cause of autism. Research suggests it is a combination of genetic and environmental factors.
Genetic Factors:
- Autism tends to run in families.
- Certain genetic mutations may be linked to autism but do not guarantee a child will develop it.
Environmental Factors (Not Proven but Studied):
- Parental age (older parents have a slightly higher risk).
- Complications during pregnancy or birth (e.g., premature birth, low birth weight).
- Exposure to certain chemicals or infections during pregnancy.
✅ What to know: Vaccines do NOT cause autism—this has been debunked by extensive scientific research.
