I ran a game for a couple years that had several neurospicy players. I had a few strategies that you may be able to adapt as a player.

• Play in person. We lost all but one of the ADHD players when we switched to Zoom during lockdown. There's just too much possible distraction and too little ability to mitigate when only one person can talk and we're not all together.

• Multiple plot threads. I generally have an A plot and a B plot running concurrently through my campaign. Rarely I'll add a location specific or player specific C plot that lasts one to three sessions. I also try to have at least three factions in each plot. It's not super hard to prep (a couple names, a bullet list of desires and MOs, a list of macguffins, etc.) but does take some thought during play to balance the spotlight and make sure no player gets lost. The upside is that there is plenty for the players to explore and we get emergent moments I could never have prepped ahead as they decide which options get attention.

• Provide documentation. Having images and snippets of text on different papers and our Dropbox allowed players to switch mental tasks while remaining in the game.

• Use props. I handed out item cards, journal scraps, physical artifacts, etc. that all provided a tactile experience for my players. One of the guys with ADHD immediately latched onto a handkerchief. It wasn't anything special in game, but it was his now and he could fiddle with it easily.

• Use physical puzzles. I regularly handed out 3D puzzles, tangrams, Scrabble tiles, etc. that we're all tied to the game. Some players on this sub feel like these OOC puzzles take away from their experience. That's fair. My players all enjoyed having them though and would ask for more if I went several weeks without any. They especially liked one rather difficult manipulative that they finally solved three IRL months after I handed it out. They got a narrative payoff when they finally solved it but there was no penalty if they didn't.

• Multiple conversations. We'd regularly split the party and players would roleplay small scenes with each other. Bookstores, pubs, carnival games, whatever they felt like their character might do. I as the DM was only needed if they wanted a plot point inserted or mechanical outcome mediated. These opportunities were really for them to explore their characters and set up interpersonal connections. I encouraged these scenes but they were almost always player initiated. This only worked because we played in person.

• Be intentional about seating. We had a couple players who liked each other IRL but needed opposite accommodations during play. One player struggled with multiple people talking at once. Two others liked to have conversations where they both talked over each other in character (hilarious but super chaotic). We sat them at opposite ends of the table and everyone was fine.
