Yup. Everyone will experience the symptoms of adhd, which is why it's so relatable. It's a disorder when those symptoms are an all day every day thing.
Also, any neurodivergent person will share some common experience coming from not being part of the matin group... I have many friends with ASD, while I'm ADHD.
While we are very different, we also get along so well because we share the fact that our behaviours and tastes are unexpected. We have much greater patience for other people's "quirks"!
True but there is definitely a threshold, above which it is considered to be a disorder. For me I definitely don't forget things, a lil bit too much tbh. Which often causes me extreme anxiety, as is the case in obsessional disorders. But i also find relatively easier tasks difficult, but sometimes I'm solving trigonometric problems in my head trying to sleep. And i also often seem lazy because of some of these issues
I'm pending diagnosis for ADHD but if I had to take a stab at it I'd say both groups have tasks they simply can/cannot do without some kind of help or personal system of ways to accomplish any number of things
Something unifying about having obtuse yet ironclad processes for doing things that should be simple and others find baffling
I would say both ADHD and OCD have issues with not having control of what takes the center of attention. For OCD you get stuck on whatever compulsion and can't move past until it's resolved. ADHD has issues with being stuck on arbitrary things that capture their attention and can't reassign their focus at will even for important matters.
They don't really seem that different in terms of the consequences they have on someone's ability to function.
That's a very informal opinion though. Not a doctor and all that.
