The general understanding is that ADHD is characterized by a spectrum of attention deficit to an extreme. The process of diagnosis usually involves a self-questionnaire. In my case I somehow managed to fail the questionnaire and the psychologist performed an IQ test. The IQ test is analyzed to see if you have a processing speed subscore that is significantly lower than your other subscores (all subscores should be roughly equal).
