I somewhat agree that there is a problem but there is a glimmer of hope. As these medical terms are used more in everyday speech they lose their medical connotations and just become new words for personality traits. A lot of people who casually describe things as ADHD are using it more as an adjective than a diagnosis. We have had medical terms make it into this usage before: moron, hysterical, humourous (we're going all the way back to the four humours).
