OCD, Obsessive Compulsion Disorder is a common issue for some with autism, although in my house I think we all have some symptoms of it.
My husband claims I am OCD because I always forget things when I leave the house. I wonder if I locked the door. Did I shut the freezer. Is the stove burner off. From what I've read, they are classic signs of OCD.
My husband is a germophobe, although not in the classic sense. He doesn't go crazy with washing his hands or using hand sanitizer. As a matter of fact, he doesn't like to wash too often because it 'dries out his hands'. But he does go through boxes and boxes of plastic gloves. He also will use a tissue to pick up the TV remote and change channels. I call him knuckles because he will pick things up, especially dished with his knuckles. It makes me crazy!
David has picked up his father's nutty 'clean' obsession. He opens a door with the bottom of his shirt and will use his elbow or feet to push it open. He will wash his hands over and over if he touches something, but I notice he does it more when his father is around. I think on some level he realizes it's a little obsessive. He'll also use a tissue to pick things up especially if he's getting ready to eat and usually when his father is home.
Michael will go into a room after someone leaves and makes sure the light is out. He is also fixated on locking doors. He will ask 10 times when we leave the house, "is the door locked."
I don't think OCD is a symptom of my son's autism. This particular affliction is most likely hereditary and in some cases, learned!
