Could this behaviour be a part of ASD?

[MotherJack]

I would be really grateful for some input on this one.

My son presents as Aspergers. Over this last week I have been made aware of him nipping and grabbing hold of anyone sat near him. I have come to expect this of him, but the odd thing is that he genuinely has no recollection of doing it at all.

I have had a second example today where he has no idea what he has done, but remembers what happened afterwards (i.e. he took his glasses off his face and snapped them in two in anger when the teacher helpfully made the whole class look at him).

Does this sound similar to anyone else's experiences?

Thank you.
