ADHD Test?

Does anyone know of a good online test to determine likelihood of ADHD? Having done more and more research on the crossover of Autism and ADHD i'm realising a lot more of my behaviours that perhaps fit ADHD, possibly even fit them more than autism depending on the day. 

Any help would be appreciated :)

  • Both often run along side eachother which doesn't help as some trates are contradicting which makes it harder to tell which 1 is more dominant. The NHS criteria for diagnosis is quite helpful then u can score yourself. I have high functioning autism but 10.5 out of 12 I scored for ADHD
