Autism spectrum disorder (ASD) is a condition that involves challenges with social skills, repetitive behaviours, speech, and nonverbal communication. While the exact cause of ASD is unknown, it is influenced by many environmental and genetic factors. One aspect that has been confirmed by science is that ASD is not caused by vaccines. Autism is a spectrum disorder as it is not able to be measured in a linear way. Each autistic person is different and will function at different levels depending on the circumstances. For this reason, it is important to understand how to communicate with a person with ASD as well as the best ways to support them in leading meaningful lives.
