First, I agree completely with all of the above statements.
You mention that treatment is in place for ADHD. Makes me wonder what the treatment is? Meds are only a small part of the whole scene.
A child with ADHD has behaviors that are not learned, but caused by their brain chemistry. That list would include:
* difficulty sustaining and paying attention to tasks at home or school;
* making careless errors, not following through with tasks or completing instructions;
* being easily distracted;
* look like they aren't listening;
* being easily bored;
* being forgetful, losing things;
* having difficulty organizing tasks, activities, or belongings;
* being fidgety, difficulty remaining seated;
* talking excessively;
* running or climbing about excessively when it is inappropriate to do so;
* having difficulty awaiting his/her turn in a game or activity;
* interrupting or intruding on others;
* avoiding or disliking doing things that take a lot of effort for a long time.
And unless, the child is taking medication, these behaviors are very difficult to change. And even if they are on meds, at his age he has learned behaviours that are hard to change. Thus, all experts say to very carefully choose your fights. There are some things that you need to ignore, must ignore because the child has not control over them. These things can be changed if you take the time to roll play, reinforce the good behavior, and repeat, repeat, repeat. But it has to become literally a part of the childs nature, and that is hard to do. So you pick one behavior that he does appear to have control over and work on that.
I recently found a very good site for parenting kids with adhd. The site is ....

I am pretty much in tune with what they have to say. So far, I would say that the only thing they left out is that when doing the consequences - make sure you don't have too many of them. You need to start with a very few things and then when those are conquered, you add new ones.
Also I suggest picking up the book, "The ADD/ ADHD Answer book," by Susan Ashley. , you will find it very helpful.
i agree with everything annie said but also agree with you that it sounds like the child could use some counseling. Even if he didn't have the pooping issue, what he had been through is enough for a typical child to need a little extra help. As for his responses, it's not that he doesn't care. He is shutting down for some reason, be it embarrassment or something else. It is a defense mechanism, and while in your home, for the most part, it seems like there is nothing he needs to defend himself from, it is very possible that whatever went on for years prior have left a lasting impact. Yelling and punishing will only accomplish the opposite of what your son wants to achieve. It will further make him feel shameful (which, if there was abuse, is a feeling that abused children may feel) and further shut down.
This is a situation where your son needs to take a step back and not take it personally. Your grandson's problems are not a result of his failures. He also needs to accept that this may be out of the realm of things he can deal with as a father. He's afraid to find out if there is abuse because he will probably blame himself for that too (why couldn't he stop it, etc.) It's time for him to be strong by admitting that he may need help.
You can't punish a kid out of having encopresis. With all the reading you are doing, you must have come upon the fact that it is a physical condition, relating to a bowel that cannot function properly, and it does genuinely surprise the kid when the fecal material comes. Not like you or me, who would have some signals. Has the child been seen by a pediatric gastroenterologist (not just a pediatrician)? And if so, is he on long-term stool softeners, to give his bowel and lower intestine a chance to heal and function properly, rather than just some stool softeners for a short time? By long-term, I mean like many months to a year? The intestines lose their ability to compress in a natural way, and they need time to get well from this and heal and begin to function again.
If this were my child, I'd get him to the specialist and be sure he does not have any further impaction, and discuss something like Benefiber for a year, and then I would take the child in for counseling also. I am sure he is not unbothered, but to pretend and ignore issues has meant survival to him, up to now. I don't think it sounds so much like sexual abuse but like shame, hidden, and hiding emotional responses in general because they never worked for him before. I would put him into pullups in the meantime, and put a diaper pail type of trash can in the bathroom, and tell him that he can just take them off and toss them without being made to feel he will be in trouble. (I would specifically tell him he is NOT in trouble, that it's obviously a medical problem and nobody is to blame for a medical problem.) I would also get him some outside help with schoolwork, so he will begin to develop a feeling of confidence there.
When a kid is yelled at enough, and ignored enough, he will develop that blank emotional response. This kid sounds like he needs some understanding.
Sounds like a lot of punishing and grounding going on ...It could of course be the meds given for the ADHD as they are known to have side effects on emotions. You mention abuse who would be suspect ?
