yes, I have had very good results with an approach that works by reversing retained reflexes. Google it, you may find a practitioner near you. Also, a good book is 'Stopping ADHD' - works just as well with ADD.
In addition, all sorts of balancing exercises works wonders for these condition.
ADD and ADHD comes from the lower part of the brain - the cerebellum - and if that is not developed well it will inhibit higher cognitive functioning. the problems with cerebellum can be cured through physio-therapeutic approaches
DS14 has worked with these approaches from from age 7 on and off through to age 12. By age 12 all symptoms were gone. 
However, his self-esteem has taken some knocks during that time and is now healing as he is slowly gaining it back.
So, my point is - heal the ADD and the lack of self-esteem will look after itself.
The mainstream establishment says that these learning problems cannot be cured, NOT TRUE!!! They are only saying that because they don't know how to cure it.
And no doubt, someone will pipe up here in a minute and try to tell us that ADD cannot be cured. But they have nothing to prove it - they are just parroting what they have been told by people who simply don't know how to cure it.
The book 'Stopping ADHD' has been written by two professors of education and brings fantastic results. Unfortunately, it has been largely ignored by the mainstream.
