What causes Autism?

April is Autism Awareness Month, which is a great time to debunk some myths about autism. Autism is caused by a perfect storm of genetic and environmental risk factors. Parents can reduce this risk by regularly taking Prenatal vitamins containing folic acid, before and at conception and through pregnancy.

Babies are at increased risk for ASD if:

  • Advanced parent age (either parent)

  • Pregnancy and birth complications (e.g. extreme prematurity [before 26 weeks], low birth weight, multiple pregnancies [twin, triplet, etc.])

  • Pregnancies spaced less than one year apart

MYTH: Vaccinations cause Autism.

FACT: ONLY the risk factors listed above are scientifically proven to put someone at risk for developing Autism. Read the most current research about vaccinations here.

MYTH: Symptoms of Autism look the same for every child.

FACT: Symptom presentation can vary drastically along the Autism Spectrum. This may include more severe symptoms like communication and behavioral challenges (e.g., nonverbal, flapping arms, meltdowns), or more mild symptoms like heightened anxiety and discomfort with changes to routines.

MYTH: Children with Autism cannot function independently.

FACT: Many individuals with Autism Spectrum Disorders (ASD) develop skills to live independently, depending on the severity of their symptoms. Check out these highly successful individuals with ASD.
