If you have at least six out of nine symptoms on the axis of inattention, but not on the axis of hyperactivity and impulsivity, then you have ADHD, predominantly inattentive. This is what used to be called ADD. If you have six out of nine symptoms on both axes, then you have ADHD, combined type. And if you are one of the extremely rare people who has symptoms only on the axis of hyperactivity and impulsivity, then you have ADHD, predominantly hyperactive-impulsive.
