How can i help my high functioning autistic sister. she is a 14 year old that isn't very social and my parents don't know how to help her.

There are social: Skills therapy groups for children with asperger's. They teach things like how to smile, make eye contact, proper body distance and talking with others. I know asperger's is an old term -but i think most of us recognize the meaning.

Refer to: : Suggest to your parents to ask her pediatrician about referring her to a social skills group or to a therapist who specializes in kids with high-functioning autism or aspergers disorder.. As this diagnosis has become more recognized, more therapists and groups are available. Her school counselor could even help with this.
