My 5 year old son has had a repetitive "tick" from the time he was an infant that presents itself (mostly) when excited or concentrating. He rocks forward and pumps his hands in toward his body then away. He does this at leas a dozen times a day. I realize this is textbook "stimming", however, he has no issues with social situations (he is very popular in his school and seeks out friends), he is compassionate and empathetic toward others, makes eye contact, and is overall a happy boy. No behavioural issues or trouble in school / caregiver setting. We took him to a developmental pediatrician yesterday, and they (based primarily on video of the stimming) think he may have Aspergers. Are there other syndromes that primarily focus around stimming? The foundation of an Aspergers diagnosis appears to be social, but we have no concerns in this regard, so the possible diagnosis is quite confusing. We took him to the doctor because of his physical tick...now having a possible Aspergers diagnosis is a shock.
