Sometimes. This movement can be common, can be present all the time or can only be there a little bit, or sometimes not at all. Each individual with autism is an individual. If it is present, I consider it significant. If it is absent it doesn't mean autism is not present.
Sometimes. Hand flapping is a common but not universal behavior in individuals in the autism spectrum disorder. It sometimes is called "self-stimming (short for stimulation), but that probably is not why the individuals do it. It is not, per se, harmful, but it can be so time-consuming that nothing else gets done; also it makes them stand out among their peers, which parents find disturbing.
Asperger's. Yes. They can but not all. Clay marzo does something similar to hand flapping. It's a way to express excitement but can also be a self-soothing strategy. Here is an overview. Http://www. Youtube. Com/watch? V=xg1ngp1ngds.
Odd question. Hand flapping is a cardinal symptom in autism, but is always associated with other symptoms. The mechanism is because autism is evidence of a sick brain from biochemical changes and is not a psychological disorder.
Self-stim. "hand-flapping" is a prominent form of self-stimulation. It is not clear why it is common in autism, but may have to do with anxiety, an inability to "connect" meaningfully outside of oneself (which seems to be what autistics have in common with blind or deaf persons, who also hand-flap and "stim" a lot), and/or difficulty with effective communication (like retarded persons, who often also "stim").
Repetitive.... ..Activities are one of several diagnostic criteria for autism.
Just one symptom. One fascinating aspect of autism is the wide array of unusual, sometimes nearly unique behaviors, associated with it. Hand-flapping, finger-flicking, body twirling, and other perseverative behaviors (collectively called stereotypies) are among such behaviors. They occur in many but by no means all children with autism. The underlying cause of the behavior remains unknown.
Association. Hand flapping is frequently seen in children with autism. It is usually thought to reflect a high level of anxiety.
Yes. I am not clear what you are seeing. The impt. Thing is to do is speak with your doctor and clear this up.
Yes. Some individuals (adults and child) engage in repetitive movements because they find it pleasurable--it's called stereotypic movement disorder. If there no problems with social interactions or language abnormalities, it typically is benign and self limiting. That said, I agree with dr. Hoffman that, if you are concerned, an assessment would be well justified.
Yes. And, the diagnosis of autism is not made by a child only having the hand flapping movements. Two other main characteristics seen in children with autism are problems with both communications and social development. I would seek an evaluation with either a child psychiatrist, a pediatric neurologist or a developmental pediatrician.
Just flapping. Not all children with "stereotypies, "repetitive motor movements that seem to have no function, have autism. A two-year old who hand-flaps when excited, but has normal social communication and no other signs of autism. May be developing typically. Less commonly, stereotypies persist into school-age. Tics and compulsions can look like stereotypies. Video it for your pediatrician to check it out.
