This, of course, is not a full proof sign that she does have ADD
, but it is something to think about.
Finally, you can not say that what worked for you will work for her. You are not the same. And, by the way, strong intelligence is fairly normal for those with ADHD. Some learn to cope and many do not and pay for it in later years.
I can give you many more resources if you want them. Thanks for asking such a good question!
