What is Autism?

To understand the signs of autism, it’s important to understand that it is a spectrum disorder called Autism Spectrum Disorder (ASD). There are many levels of Autism that can affect how a person acts, learns, and expresses themselves. Autism Spectrum Disorder affects how an individual may socially interact, behave, learn, and communicate. Individuals with Autism Spectrum Disorder also show signs of OCD, ADHD, repetitive behaviors, and obsessive interests.

Socializing can be extremely challenging with Autism Spectrum Disorder. Depending on what level of the spectrum a person is on, learning and thinking can range from extremely gifted to needing severe help. Individuals on the spectrum can also be overstimulated by lights, sounds, and spinning objects. Some may even exhibit sensory-seeking behavior or have sensory triggers.

Signs of Autism generally appear in the first two years of life. Children and adults can have Autism Spectrum Disorder. Below are the top 20 signs of autism in children and adults.
