People with autism have social impairments and often lack the intuition about others that many people take for granted.

Cantu told Buzz Feed News that, contrary to the way the community is often portrayed, everyone on the autism spectrum has different tendencies and preferences."For example, just because someone is on the spectrum, does not mean they have social anxiety," she said.It is distinguished not by a single symptom, but by a characteristic triad of symptoms: impairments in social interaction; impairments in communication; and restricted interests and repetitive behavior.Other aspects, such as atypical eating, are also common but are not essential for diagnosis.
