10 years ago when I was 6, I was tested for autism and ADHD. I didn't have them. I don't remember what they did, I found the paperwork one day when I was digging through my stuff. My parents had followed through on their promise of "If you keep misbehaving we're taking you to a doctor." Anyway, I feel like I have ADHD or ADD. I am easily distracted and I have trouble paying attention, and I'm pretty forgetful. I brought it up one day and they said they had me tested and I didn't have it. I couldn't find any other paperwork from 2010-2019, so the last time I was tested was 2010, soon to be 11 years ago. Would the test still be accurate?
