It seemed relevant when I started typing, but idk, I'm tired 😂

Understanding that hyperactivity is secondary to an underactivation of the brain in ADHD was very enlightening for me. Since then I've taken to napping whenever I feel tired instead of deathmarching through these phases whenever possible. Yes, it messes with my sleep schedule a little bit but it's better than the alternative.

I know when I dream o seem to have ultra ADHD, nothing is consistent and I'm constantly moving from one subject to another and not able to focus on a single plot/conversation/idea etc

I don't have a diagnosis, I only score quite high on autism self-tests, but something I also experience is that the mental exhaustion seems to build up in the background over the course of an eventful day, and then in the evening when I'm home, it takes maybe half an hour before it feels like my brain is pushing against my skull in all directions and it becomes really difficult for me to take in new information.

I can also kind of work against those symptoms by meditating or perhaps rather not taking in new information for a few minutes. Naps don't work as well, because it seems like blood circulation is vital for fighting off those symptoms, but I'm also just likely to fall into a really intense, yet not very deep, sleep for a few hours.

It kind of feels my brain caches everything it wants to retain throughout the day and then starts processing it in the evening all at once. And then as it's processing it, it builds up something which needs to be transported off. The closest thing I've heard in that regard, is that mental exhaustion leads to a glutamate buildup: https://www.newscientist.com/article/2333230-why-thinking-hard-for-several-hours-can-leave-you-mentally-exhausted/
It does feel like an extreme version of mental exhaustion.

And yeah, long story short, maybe others' brains are able to start processing in the middle of the day, due to this sleep-like brain activity?
Could also be, though, that my social anxiety prevents me from doing this sleep-like brain activity.
I do also have a reputation for exceptionally good memory, so maybe my brain just caches the whole day, because it can. Or this intense post-processing is how it's able to achieve the exceptional memory in the first place, which also seems very likely.

This braindump brought to you in the middle of the night, after one of those multi-hour naps. My brain is still not done processing the day, but about 90% there. 🥴

Doesn't matter if I nap or not though, I can't go to bed early enough ever because I suck (and I like videogames too much and staying up late is how I can get alone time to play them).

I think sleep schedules are the same though. You need people to do the gathering during the day, but you also need someone to watch for lions all night. I think I'm very thoroughly the latter. While it does take some doing and a little caffeine, I'm much happier and better adjusted sleeping during the day every day.

For example sleep deprivation alters dopamine receptors and signalling, which is thought to be one reason people feel temporarily “wired” or oddly alert after being very sleep-deprived.

I imagine it’s related to that.

I'm sure I'm oversimplifying.

anecdata

Oooh, I like this word. 🤣😜🤌🏼

I'm glad they're finding some stuff they can actively track, though. For the longest time it seemed diagnosis was solely based on subjective testing. I'd really like to see some objective things - just to shut up the deniers, if nothing else.
