Sensory issues usually go along with other disorders. They can be distracting. Sonic has them galore. It part of Autism Spectrum Disorders (ASD) with him. He is sensitive to noise, crowds, certain texture foods, certain types of material (and no tags on the backs of his shirts) and has an unusual sensitivity to smell...he can smell things like a bloodhound. Sonic still has sensitivity to stimuli, but he is in no way hyperactive. He was as a little one, but now it is a big chore just to get him to move! I don't know that the two things have anything to do with one another. Most sensory sensitive kids do pick at their clothes and skin a lot and often cover their ears when noise is too loud. Some can not tolerate being in a busy environment without melting down. Sonic was like this once...he still doesn't like it, unless he knows the kids, but he does not melt down anymore over it.
