I have been dxd with ADHD since I was young. First dx we got I believe... I have also often wondered if I belonged on the Autism spectrum as well. I had neuropsych testing done last year. Asked him about how they test for Aspbergers in adults. He told me that generally speapking they don't after out of school age. He told me that the treatment for adults is really just learning to compensate with behavior modification therapies mostly CBT or DBT. The only reason they test for ASD in adults would be on the lower functioning end if it were somehow missed in childhood. But I do have to still get all my imaging done...so Idk if the neurologist I have been referred to for imaging diagnostics will have a different opinion to offer. (The testing i have been referred for is to check for any signs of brain injury or trauma because I have sustained quite a few blows to the head various types and also because I carry a rare Comt gene mutation that they believe may put me at higher risk for early onset dementia, alzheimers, or possibly even Parkinsons even tho I don't have family history my genetic mutation is not hereditary.)
