ADHD is best described as impaired self-directed behavior.
The kernel of motivation may exist, but an ADHD victim would fail to follow through on that motivation, to their own detriment.
Either due to lack of concentration, lack of planning, or lack of execution. Often all of the above.
It is a general dysexecutive syndrome that that may impact all higher order cognitive functions.
Motivation, on the other hand can also be impaired by depression (aka "learned helplessness" - which is not uncommon in ADHD), but that would not be ADHD in itself.
