Do folks with ADHD 'stim' (and what is it)?

Isabelle and David talk 'stimming'-AKA "Self-stimulating behavior": what is this word, where does it come from, and what does it mean to 'stim'? Perhaps spoken of more in the autism community, stimming applies to ADHD also, and can connect to not just how we use sensory inputs as ballasts or balance systems, but also unique indicators of a ADHD culture of our own. David and Isabelle dig deep with some adorable sneezes, more on the ballast systems of ships, and the tail expressions of animals along the way.----David and Isabelle describe how cat and dog tails are completely different in indicating their state. David’s cat was so still with just the tip of its tail bobbing back and forth, and David pointed out that that’s how you can tell a cat is happy. Which is the exact opposite of how you can tell a dog is happy, with an exuberantly wagging tail. And maybe this relates a little bit to stimming, in that someone might interpret Isabelle’s bouncing leg as an indication of one internal state, when actually she is stimming and feeling very calm as she does it. There could be two ADHD camps here: one for dogs, one for cats. Perhaps most ADHDers would align with dogs, as in we tend to vibrate when we’re happy. David knows when he’s still and quiet he is very alert and something’s wrong. Isabelle’s dog is currently whining at the door and she is like her dog in that she gives her all her needs and yet she has more needs? Isabelle is curious about internal stimming, like when she ruminates or revisits things in her head to self-stimulated. David talks about this as acting in or acting out, and maybe he’s doing some action, or he’s thinking or connecting with an internal world. Stimming is thought of as an action, that is repetitive or relieving in some way. Acting in and acting out was something David was naming 20 years ago, but now we use the term “stimming” — and it’s doing something to keep your heart rate up. Isabelle did not see it used around ADHD but it does connect, but she sees it a lot around AuDHD — it comes from diagnostic origins, but the function of it is what David describes as exhaust. If his engine is running, there’s going to be something going on somewhere. Slowly picking at a nail, feeling the tension of his pants, something to help him regulate his attention—like a ballast. This sends Isabelle off on a tangent about being a tween going to see “Titanic” because she was into boat architecture after seeing documentaries about the Titanic about the ships ballast getting flooded—the idea that you have these big walls that are designed to bring on some water  in order to balance the ship. Isabelle walks around with Trex arms, and it’s like she is letting some of the world in and that helps her pick what’s coming at her on a sensory level, because she can’t really tune out the rest anyway, it's like taking in some stimulation to stay afloat. David describes how other ballasts could be biting down on leather when getting an amputation. If you give your body something to do it can distract it. While Isabelle isa bout to go on a tangent about pain theory, her dog needs to go outside, and so indeed, behavior is communication. Now David sneezes. And it’s adorable. And he has to fight the reflex to not say “F you” back, because he has sneezed adorably for a long time now and his friend David C. Would always tease him and so he’d respond lovingly with an “F you!” And so he now needs to describe it all. David then segue ways to a definition of culture. Isabelle studied anthropology and archaeology in college, and remembers a professor saying that you know a culture exists when there is an in-group and an out-group and that culture is a set of adaptations to a human’s environment. For example, chimpanzees, they stick a twig in a termite mound and then they eat the termites, and thinking about it archaeologically that a being used a thing to do something that nature did not use it for, so when archaeologists speak of a culture its around distinct patterns of how things were made and the area where people lived in. If we were archaeologists of the future, if we came back to earth, could we notice distinct enough artifacts that would indicate there is some difference in this group? Or we could think of it as a series of adaptations for the environments in which we find ourselves. Referencing the NYTimes article, the parts we can resonate with, ADHD is about so many more things than that. So dysregulating because it’s 70% accurately, you just left out so many important details and experts and points—that thing that pains Isabelle is that this article is so long and takes so much energy to digest and is just an aspect of the book. David points out that it states that medicine has diminishing returns, because OF COURSE it doesn’t mention that medication is intended to be used with therapy and of course the medication doesn’t help you with the self esteem repair or accommodation strategies so in a vacuum you get diminishing returns. Isabelle is so on board and also frustrated that this is coming at a time when the world is extra scary and intense. David names that he thinks we would see signs of ADHD culture--organizing in piles, the sheer volume of fidget spinners, etc. Isabelle agrees, the material culture alone would create an interesting set of indicators that something different is happening in certain households that is unique and also in common with one another.Stimming (aka "Self-Stimulatory Behavior) -originally attributed to autism spectrum disorder (ASD), but also occurs in neurodivergent AND neurotypical or allistic (non-autistic) folks. It means repetitive physical movements, sounds, or actions that someone engages in (aka leg bouncing, finger tapping, hand flapping, twirling hair, humming, repeating words, staring, pacing, doodling, playing with fidgets, chewing gum, smelling or touching things..so many stims!).Useful for: so many things! For when your senses are overloaded or your understimulated, can help you focus and concentrate, can be a way to learn about or interact with your environment, or to cope with anxiety, stress, excitement, or big feels.Culture (Source: Oxford Language Dictionary): "the customs, arts, social institutions, and achievements of a particular nation, people, or other social group." OR, "anthropologically, culture is defined as a complex, shared system of learned beliefs, values, behaviors, and symbols that allows a group of people to understand and interact with the world. It's a dynamic, evolving set of practices and ideas that shape a group's identity and way of life" (from sapiens.org)The notorious NY Times article ("Are we thinking about ADHD all wrong?" by Paul Tough) David and Isabelle are referencingChimpanzees eating termites like a lollipop (AKA chimps having a material culture)Ballast: YES these are compartments designed to be flooded and dispense with water to help balance a ships weight and regulate how buoyant it is in water (how it floats) (see Wikipedia definition of "Ballast Tank" for more) AND superintricate maps and explanations of the...
