Evaluation: You should have an evaluation by a psychiatrist to be accurately diagnosed. If you are already seeing one, mention to them that you think may have symptoms of the disorder so they can explore it further.

get tested: There are tests to take (performance based) that will help identify executive functioning problems and susceptibility to distraction. Only a psychologist can administer these tests.
