does ADHD give you 'brain fog'? like having your head just filled with static or white noise, or feeling like it's "heavy" and being held underwater? because I regularly have a lot of pressure in my head, accompanied with this 'foggy' feeling in it that makes it impossible to concentrate on anything and a friend told me it's a symptom of ADHD. I have no idea why or where it comes from, because it seems to happen regardless of how much sleep I get or whether I eat/drink or not...
The static thing is a yes. And brain fog is definitely a thing with ADHD. It’s one of those things, however, that it’s hard to find reputable advice about. I would personally go through a bunch of these articles over at ADDitude Magazine.
