i tell people that the key symptom for me at least is hyper-focus its just that sometimes i hyper-focus on one thing to the exclusion of everything else even peeing my pants as a kid because i couldnt stop what i was doing to go to the bathroom other times though my brain is trying to hyper-focus on everything with every little noise or flicker of light or thought being a distraction that cannot be ignored so i am not able to concentrate on any one thing
