Afaik, there is only so much that can be done there without medication. Medication is the single biggest impact on ADHD (not so much other things, such as Autism, but ADHD definitely).

Otherwise, the main thing that will need to be trained is you. You could have her write out an outline of what she wants to cover and cross off each item as she gets through it, so the visual reminder helps her... but she won't remember to even start on the outline unless you remind her, right?

I am no expert, but this video helps me understand things: https://youtu.be/SCAGc-rkIfo.

I think the best thing to help her-because I have a friend who is strongly on the AuDHD spectrum and is helped a lot by his incredible girlfriend, is converse with her in a series of questions that creates external structure.

Not everyone's brain is the same of course, but the communication issue is that her brain is running faster than her memory can keep track of and her mouth hole can finish thoughts coherently. The information is there, its always been there, she struggles to parse it in a neurotypical way. What you have to do is take away the ADHD "decision matrix hell" that our brains get trapped inside and create a single track with limited offshoots so we do not get immediately overwhelmed and derailed.

Try sitting her down and simply ask a series of questions about whatever topic at hand. Who? What? Where? Why? Don't ask how because that can trigger a tornado of thought train processes. But get her to work inside of a structure that's simple. Each of those questions should boil down to an answer less than 10 words for most things. It might help to start this on paper too, leave her one to two lines for each statement.

This could help in professional communication too if she can start to practice answering everything in the four-W format, it will be a lot easier to keep things clear.

Glad to see she’s medicated, and that’s a bummer that it isn’t helping. One thing I make great use of (and I am well aware I will be immediately downvoted into oblivion for saying this) is an LLM. I can feed my disjointed and unorganized thoughts into it, and then ask it to spit me out a coherent run down of the idea I am trying to get across. LLMs excel at this because of what they are: Large Language Models. Self-explanatory. They are utter shite at numerous other things; for example, it simply cannot give me a mockup of what my kitchen cabinets will look like because it’s not a a Large Image Model. It can’t “see” the difference between 3 or 4 cabinets. But it nails the linguistic organizational tasks for me. I know this is lemmy, and I will receive much scorn for my use of this specific tool, but with my AuDHD this thing is a game changer when I am thinking faster than I can get the words out verbally.
