It sounds like there is more going on than just ADHD. I am thinking some executive functioning deficits that almost always accompany ADHD. Here are a couple of good resources:



Executive Function...
"What is this anyway?"
Chris A. Zeigler Dendy, M.S.

Parents and teachers are often baffled when students with attention deficits, including those who are intellectually gifted, teeter on the brink of school failure. Recently researchers may have solved part of this challenging puzzle; deficits in critical cognitive skills, known as executive function, may interfere with a student's ability to succeed in school. Practically speaking, executive function deficits may cause problems for students with ADD or ADHD in several important areas: getting started and finishing work, remembering homework, memorizing facts, writing essays or reports, working math problems, being on time, controlling emotions, completing long-term projects, and planning for the future.

Executive function: A new lens for viewing your child
This theory of how we mentally navigate life offers a new way to view a child's strengths and struggles.

As each of us goes about daily life, numerous mental processes and skills help us plan for � and respond to � the tasks, challenges, and opportunities we face. Researchers and psychologists have coined the term executive function to describe this constellation of cognitive controls. The dynamics of executive function affect every one of us � young and old, as well as those with and without disabilities. It influences our performance at school, on the job, our emotional responses, personal relationships, and social skills. Yet executive function plays itself out a little differently in each of us; each individual is uniquely strong or competent in some cognitive control areas and weaker in others.


Based on the the neurodevelopment web site you posted - it seems that they are promising to help in these areas. While outside assistance may be great, as you've found it is expensive. I suggest you pursue these issue through the school first. In theory, if EF is what is causing so much trouble for your very bright child, they should teach the strategies to help her initiate, plan, organize and execute on her work so that her gifts are recognized.

How can you do this?

When you said she has been tested twice - was this by the school? Have you ever referred her for a special ed evaluation? If not, I would start with the school. If she has been evaluated already for special ed, you are entitled to an IEE (Independent Education Evaluation) by a credentialed independent evaluated of your choice paid for by the district. This professional can use diagnostic testing to help understand what is going on and what is needed to help your child. If your child qualifies for special ed (and doing well in school does not necessarily preclude one from sped), the school should provide the needed instruction to help your child be more efficient, productive and successful.

If she hasn't been evaluated by the district yet, their evaluation may be sufficient to shed light on what is going on. But, again, if you disagree with the results for any reason (ie they don't have comprehensive enough recommendations), you can then request an IEE.

Even if you find a medication that works, it doesn't magically provide the EF skills that are needed for success in school and life. They will simply make it easier for her to access instruction for the skills and will help her better remember to use the strategies.

As far as techniques at home - I like these two practical books:

"Late Lost and Unprepared"
"No Mind Left Behind"
