you have tried lithium ? or volume?

another idea to help with the Go TO room will have to be placing all other garbage bins in a Locked closet it will be a inconvienience for you but when he only has one garbage.. also in that room perhaps make him a bean sifting bowl , you can buy dried beans or noodles and put a good amount of them in a large tupper ware bowl, have him sit and sift the beans from one bowl to the next use cups and spoons to fill the bowl or jars this may occupy and satisfy his need to place things from here to there.. put items of intrest in the bowls and that have covers or large storage containers , he may be sensory seeking too. or this is how he controls his anxiety.. you can use the bean bowls as a re-direction and put sight words in there too nice way to learn and a diversion..

Helper: the only meds that would control my son from aggression once he's ramped up are KNOCK-OUT drugs. Those come in shot form (not bills). I can not get those drugs because I'm not a RN. And I don't want to knock him out. The better solution is to continue our behavior plan which is to provide soothing activities when he's slightly upset before he ramps up too much. We're already doing that. But locking up the trash would ramp him up really fast. So I can't do it right now. Not if I want him to stay safe and for me to stay safe.

It sounds like an impulse control problem, but it could be something else. He might associate throwing stuff away with cleaning up, and he might have gotten a positive reinforcement for cleaning up once. Positive reinforcement in ASD can quickly become an obsession, and can create some very troublesome behaviors.

See if you can figure out the reason first, but I suspect it is just a repetitive behavior.

I would try traditional ABA with this one. Start by giving him something to throw away, and ask him to wait ten seconds before doing it. If he can wait ten seconds, then give him a reward. (We always try to keep a little candy hidden away somewhere.)

If he can't wait ten seconds, then try five. If he can wait ten, then gradually work it up to a few minutes. (If it helps, you can promise him the reward in advance, but you have to do it in such a way that he always ends up with a success and a reward. So if he fails at first, he can still earn the reward, it just takes longer.)

By creating a reward for self-control, you are using the same part of the brain where the fixation was created. This might stress him out, but it will eventually give him two positive results to choose from.

That's the theory, at least.

HE is frustrated and it is throwing him off his patterns the garbage picking is a special intrest. does he have any topic of intrest he likes ?? .Direct him to the Go TO room. and what does he like for a treat ? Get it in hand, try to coax him to the room . The issue Is his brain reads that pattern and the OCD is a comfort for a very over active brain...it is the same and repeditive. you are encourageing him to learn how to self sooth and use sensory tools, can you use picture word association? .. Changing his patterns This will be a challenge, I would be good if you had another helper, with you so you are safe. Creating a new pattern will aggravate him. Tell him we will go to the GO TO room "calm, quiet, and friendly. in a very monotone voice.continue the montra calm quiet and friendly, use things he likes treats to change his pattern.. if he continues to be self injuring you may need to get a sedative, talk to your doctor, there are so may that work. the challenge is finding the right one, but when he gets self injuring he is over frustrated you almost have to re-direct him again.. offer sensory sticks or balls those sort of vibrate, get a message chair, I have seen those ones you plugin to the wall that sit on the chair.. and for many they are a big help, if he hit's with the sensory tools of course take it away, but I think I would look into a sensory type stick you can google those used in OT therapys.. if he maintains getting violent with you he needs a sedative. do some bean sifting you sit down in the middle of the floor in the GO TO room even when he is having a fit and repeat his name very calm and sift the beans... engage with him pick up things your self and put them in the new garbage or pail in the GO TO room see if he will engage. put a tootsie roll or a treat in there and try to see if he will engage .. GOD Bless.
