Is this aggression evidenced by cursing or physical abuse?
I don't know, but if the quotes in the article are any indication, it seems that amongst those with autism who do act out, biting is not uncommon.
I don't think that "normal" frustration is comparable to autism, though.
"Autism is a disorder of neural development characterized by impaired social interaction and communication, and by restricted and repetitive behavior. The diagnostic criteria require that symptoms become apparent before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood. It is one of three recognized disorders in the autism spectrum (ASDs), the other two being Asperger syndrome, which lacks delays in cognitive development and language, and pervasive developmental disorder, not otherwise specified (commonly abbreviated as PDD-NOS), which is diagnosed when the full set of criteria for autism or Asperger syndrome are not met."
I understand the difference, and in some respects your obviously right. I’m not trying to make the case that being elderly is like being autistic. Heck, I’d be slamming myself with thoughts like that.
What I am addressing is diminished capacity.
Both the autistic person and an elderly person have reasons for their bouts of anger. Neither are particularly justified. To them it sure is.
My grandparents ran a nursing home. Every once in a while a client would get angry because someone stole their socks, or their shirt, their pillow, or even their tools they hadn’t had for a decade or more.
The autistic person has an equally reasonable (to them) issue that sets them off.
And you’re right, the elderly person isn’t generally going to bite someone. They may take a swing at someone, if they’re of a mind to.
