To think that stimming (especially destructive or very intense) is potentially not helpful or even harmful in the long run?

I’ve seen a lot of advice that stimming behaviour in individuals with autism or adhd is helpful and regulating, however instinctively this feels wrong to me.

The brain is plastic and can be trained to expect certain things and I feel like that failing to redirect ourselves or our children to more healthy ways of experiencing overwhelm is only making stimming worse. And possibly the overwhelm worse in the long term.

this is backed up by several Reddit threads, where people said allowing themselves to stim, made the stimming worse, but the mainstream opinion is to let the stimming happen.

Instead of teaching life skills and how to get through day in an off ten overstimulating world, is it healthier to rely on potentially problematic behaviour as a way of getting by.

I know I’m probably kicking a hornets nest here, but this is not to suggest that ALL stimming is bad or anything like that. We don’t know everything about the brain or our behaviour, so I think it’s good to discuss things so we can work towards helping everyone rub along together. I hope this makes sense.

The OTs that i spoke to in regards what to say to parents said that the only one they say to reduce in children is spinning as it stimulates rather than regulates and to try to redirect towards rocking or have it as a very controlled spin. Other than that allow the child to do what they need to do to regulate their sensory systems.

Thankyou for that. One of the GS is a spinner among other things so I will try calming that or redirecting because I have been wondering as it does seem to make him go some after! I have been letting him spin a bit in the kitchen Also he jumps all over the settee and then spins off rather wildly! No amount of telling him stops him day in day out and it can be dangerous so I'm thinking a distraction technique is needed there similarly?

Don't mean to be hijacking the thread.

Did I say you just tell them to stop and problem solved? No I didn’t. But what you certainly don’t do I tell them and their parents that actually the ocd compulsions are their way of regulating.

Who says? You’re a psych now are you?🤣 Pacing is soothing for my son and always will be. His OCD which is being treated with therapy and medication is completely separate and different to his stimming .

I completely agree with you.

I have a child with the most severe form of autism, GDD and suspected ADHD (GP wanted a sign off from a teacher to confirm his diagnosis).

When my child was a toddler he would suddenly rock so violently that I would get injured. I put a stop to that along with the flappy hands, vocal stimming and walking on tippy toes.

I also found that when he was encouraged to do things like spinning (by his speech therapist) he would go absolutely feral. I told her not to do that because he would get himself into a situation where he wouldn’t stop. She argued that autistic kids like it. So I sat back and let her deal with him. It didn’t calm his nervous system - it put him into a state where his behaviour continued to escalate until the point he would physically injure himself.

At home he would need more and more to satisfy his sensory needs and would run full force into furniture.

My concern was all of his behaviours were preventing him from making friendships as well as preventing him from interacting with the world. His Paediatrician told me that we need to get him out of his world before the age of 9-10. So that’s what I focused on.

I was so successful in stopping his behaviours that new Paediatricians told me they could not tell he was autistic.

He talks (previously he was non verbal), he’s made friendships and he plays with others.

I absolutely refused to lean in to his behaviours. I told him if he felt it necessary to carry on then he should go up to his room and do in private and that he shouldn’t annoy me.

I support him. I’ve given up my amazing career for him. I refused to be home all day with a kid that was non-verbal, who groaned, moaned, yeeped, rocked, self harmed (he used to hit himself in the head), who flapped his arms like a bird and walked around on his toes.

The GP might have wanted information from a teacher to support a referral for assessment, but they didn’t need this to “confirm a diagnosis” - because GPs don’t diagnose ADHD. Why wouldn’t the teacher provide the requested information?

If you found telling him to stim in private so he didn’t “annoy” you so effective that his stims disappeared, he became verbal, and he started playing with others and making friends, with your terribly caring interventions making such a difference that a paediatrician genuinely said they “could not tell he was autistic”…you’ve either found a miracle ‘cure’ (not a thing) and should get in touch with some medical journals, caused intense masking which is likely to cause him a ton of issues as he gets older, or he wasn’t autistic at all in the first place.

Either way, what you’ve described isn’t “the most severe form of autism” is it? (Not that he could have that anyway, as it isn’t a thing).

You don’t stop OCD by telling children to stop pacing. Quite the opposite, if you tell a child with ocd who paces to stop pacing- you make it worse!

ocd Is very common with autism so I’d say it’s enough to be wary of the potential negative side to certain stimming behaviour, especially when it’s children.

@Muffinmam

GPs don’t diagnose ADHD though?

No, they don't, nor do teachers 'sign it off'. I've not heard professionals use the term 'most severe form of autism' either, what is that @Muffinmam ? Have you reversed it now that your child is verbal and doesn't engage in repetitive behaviour? Communication and repetitive behaviour is part of the diagnostic criteria. Have you cured him autism or reduced him from being the 'most severe form'. If so, have you contacted medical professionals about this? I'm sure there will be many interested in your method used to cure autism.

Ok, but have you considered that chronic anxiety and threat-load increase OCD risk? Or that masking and suppression increase anxiety? And that suppression is more plausibly a risk factor than stimming?

These would be examples of stimming behaviour that I have witnessed from children close to me. Pacing, spinning, loud noises, jumping, rocking, head shaking. Instead of calming or grounding it seems to create a negative cycle that leads to them doing the behaviour more often or more loudly, violently etc if it’s not interrupted and replaced with a different behaviour.

I do not think these children just not get over it and their struggles should be dismissed. But I don’t think this behaviour is helpful and instead seems to be leading to more harmful behaviour and I worry about the potential harm letting them behave in such intense repetition is for their mental health.

I’m very sure you don’t understand but I think you have good intentions. It’s very difficult to explain over a Mumsnet post. Have you heard of Temple Grandin? She is a professor of science in America, and a very famous autism advocate as she was one of the first individuals to publicly share her experience of autism. There is a film about her life which covers these topics in detail. I think you would find it really interesting.

Yes so proper evidence then?!

Far better to stim than self injury/meltdown etc.

That was literally my first thought when I read this post! “Oh people on a REDDIT thread said this? It must be true!

FWIW my son’s stimming has changed over the years as he’s grown physically and emotionally.

"I just feel like encouraging children to behave in intensive repetitive behaviours is not going to be good for their brain."

Firstly, this is just your feeling, it's not based on anything at all that's objective. Secondly, in general parents don't encourage stimming, and ignoring it is not to encourage it. Thirdly, the stimming behaviour originates from the child, it isn't being imposed on their brain, it is part of their make up. People have clearly described how being forced or required to mask their stimming causes them issues, which is the total opposite of your "feeling" about this.

I think you have some specific issues with how the children or adults that you know with autism are being parented or cared for, and you personally find stimming to be something that upsets you. That's my feeling about this.

Only because I am questioning if it IS harmless. Maybe it is maybe it isn’t, I just feel like encouraging children to behave in intensive repetitive behaviours is not going to be good for their brain. BUT obviously it heavily depends on the person and how the behaviour is being displayed. Ie is it escalating in intensity or occurrence or leading to anxiety or in itself masking something that could be fixed.

not saying this is the case with you necessarily, more talking generally

Suppressing non-harmful autistic regulation in favour of cognitive “skills” doesn’t eliminate dysregulation, it postpones and internalises it. The long-term risks of that are VERY well documented.

You can teach, emotional literacy, planning, exits, boundaries, breathing, grounding etc which can be useful, but none of them discharge sensory load the way a stim does in real time. Replacing a reflexive nervous system response with a conscious override is masking, which keeps a nervous system in a state of unresolved stress.

You're not talking about autistic stimming, then. You're talking about OCD.

  • Autistic stimming stimming does not cause OCD
  • Allowing stimming does not increase OCD
  • OCD is driven by intrusive thoughts and threat reduction, not sensory regulation.

Sure, they can be co-morbid or exist in isolation, and a clinician would need to assess what the route cause of the repetive movement is, and what purpose it serves, before decreeing it "harmless" or "problematic".

ocd Is very common with autism so I’d say it’s enough to be wary of the potential negative side to certain stimming behaviour, especially when it’s children.

My DS stims a LOT by bouncing on his heels and uttering a little groany noise. It’s how we know he's content. If he’s unwell or unhappy the stimming stops and we are always relieved her hear him resume his bouncing again. Politely, OP, you know very little about this and probably need to have a lot more experience of being around neurodiverse individuals before you make sweeping conclusions about their natural behaviours.

Yes, my adult son has his happy noise. When he stops making it it's the first sign I have that he is feeling unwell or anxious.

If stimming helps soothe someone whose nervous system is heightened why is that a problem? I have two autistic grandchildren. One stims by jumping up and down and arm flapping and the other doesn’t but masks very effectively. She tends to explode or have a meltdown so they both cope with a disregulated nervous system in different ways. So long as they don’t inflict harm on themselves or others why worry?

@ThatWaryGreenBiscuit

You seem to be saying that you are against destructive behaviour and self harm, which I feel we would all agree upon but you go on to say that it’s the repetition that isn’t good, and give the example of a dog chasing its tail.

I know that we don’t fully understand the brain. I think that only the smallest percentage of people in this world consistently do everything in their power to maximise their mind and body. The rest of us often choose to not stop doing something, because it simply makes us feel better. That is the most normal approach.

So when it comes to people with ASD, why should we expect them to fight against something that is helpful to them in favour of a possible undefined benefit in the long term. No one else does this to such an extreme.
Would it be better if I did more exercise? Probably yes, but because I’m a human and not a robot, I don’t feel the need to be programmed into the best possible model of myself. I don’t need an upgrade!

Of course not everyone needs to do everything all the time, but there’s a difference between saying a potentially harmful behaviour is actually good for someone and saying, this behaviour isn’t probably good for me, but I don’t have the headspace to deal with it right now.

Could you give some concrete example of what you consider non-helpful stimming, and why you think it intensely repetitive behaviour might cause escalation to harmful acts?

I have met a couple of parents whose children have autism and I have wondered when they have asked them to calm down why they are stopping them stimming and this has been in their own homes. I don't understand why they ask them to calm down. And both these parents are highly educated. Other parents I have been in contact just seen it as part of autism. So I have privately questioned whether they are right to say calm down.
Personally I feel better to be natural and let a person's nervous system function in its own way. I feel blocking things makes a pipe burst further down the line.
I'd never stop anyone stimming to fit in with a perception of conformity unless they were going to hit someone or something in the vicinity like in a shop.
People obviously stim for a reason. I would personally compare stopping stimming similar to when people used to try and get left handed people to write with their right hand.

Some points as I don’t know how to reply:

If the activity is genuinely non helpful then of course I don’t have a problem with it, why would I?

I am questioning whether certain stimming behaviour that is often seen as harmless or beneficial to the person is actually harmful. For example intensely repetitive behaviour could actually be feeding into a loop of behaviour that will escalate into more harmful behaviour or ocd type behaviour who’s definitely not healthy to a person. Especially as many individuals who stim may also have ocd struggles or tendencies.

I only mentioned Reddit as it’s difficult to find open discussions on this without it spiralling into defensiveness. a this thread was discussing what I was thinking.

No I would never tell a child off for stimming or make them out to be a bad person.

I don’t see why it’s not possible to discuss the best methods for helping autistic or adhd people when you have them in your life. Not every piece of professional advice is solid so just because the research has a conclusion right now doesn’t mean it’s right or right for everyone.

You're not talking about autistic stimming, then. You're talking about OCD.

  • Autistic stimming stimming does not cause OCD
  • Allowing stimming does not increase OCD
  • OCD is driven by intrusive thoughts and threat reduction, not sensory regulation.

I can no more stop my severely autistic non verbal DS from stimming than I could part the seas. He gets plenty of looks and stares from people like you, you get used to it. It's in every noise, every movement, every second. If he's not hurting himself or anyone else then happy days, he has no sense of where he is in space, bouncing, jumping, stomping wiggling his arms are the way his brain is compensating for that, without it, he has inadequate vestibular input. It's quite clever really, very interesting to research if you wish to educate yourself.
Imagine you're in a car going backwards with a blindfold on, four different songs playing at in your ears at once. That's how he feels if he doesn't stim, in a crude way it's similar to how a blind person's other senses compensate. Why would you want to stop that? Would you prefer his meltdown? It involves headbanging, concussion, biting himself down to the bone, unbelievable screaming, serious violence. I know which I prefer.
There can be harmful or antisocial stims, which require redirection, this requires work, and effort I suspect you have no idea about. I won't go into them as I expect that will reinforce your negative stereotype, but please understand it's not as simple as just stopping them, especially if coinciding with a learning disability.
