Autism is a very difficult disability to understand. Usually, there are no outward signs pointing to an individual having the syndrome. Autism is also not a "one size fits all" syndrome, it is a spectrum of disorders that have to do with developmental, social and behavioral issues. An organization has put together some very useful tools to help others understand what you and you autistic loved one are going through.
In an effort to ease the fears of and provide encouragement to all people with individuals with autism in their lives, Autism Speaks has created four support tool kits, each designed specifically for the following groups:
The purpose of each kit is to help teach family members and friends more about autism and its effects on families, and provide resources and support to enable them to lead happy and successful lives with their loved ones with autism.
This is just a starting point in helping others to understand the Autism Spectrum Disorder, I encourage you to use these resources and grow in your understanding of the disability.
