Autistic Spectrum Disorder is a developmental disability where there is a triad of impairments; social communication, social interaction and social imagination. Autism is called a spectrum as, although all individuals will suffer from difficulties in three main areas, their condition will affect them in very different ways. No two people with ASD will have the same difficulties. Asperger’s Syndrome is on the Autistic Spectrum.
This chart is good information about meltdowns. *** But please remember that adults with ASD have "meltdowns" too, although they are very different***. As an adult it's not possible to throw a tantrum so the issues shown on the diagram manifest differently. (And differently in different ASD adults.) What's needed is acceptance and helping that person decompress and destress before a meltdown happens. -- http://www.theautismdad.com
