difficult child 2 is not diagnosis'ed with ADD but I have thought she has had it for a long time. I recently had a neuropsychologist exam done on her and her official diagnosis is cognitive disorder - not otherwise specified. However, I have been told that she would appear in the classroom as a child with ADD. I think the only reason she didn't get that label was that I took her to a neuropsychologist that specializes in Lyme Disease and other brain injuries so he used that diagnosis instead.
I am taking her to a tutoring place that works on study skills for kids with ADHD. The director of this center told me that ADHD/ADD are really a description of symptoms with many different causes.
My daughter's neuropsychologist exam revealed weaknesses in visual comprehension, slow processing speed, and working memory when interrupted as well as other areas. Some of the suggestions were teaching her note-taking skills and active listening skills, having the teachers give her copies of their class notes several days before class so she could pre-study, and teaching her to read out loud to herself to add auditory comprehension to her reading.
I don't know if most kids with ADD have the same weaknesses as my daughter's. Has your daughter ever had a neuropsychologist exam? Whether they call it ADD or not, it might uncover areas that you could then address. If this isn't possible, I can look for more details from my daughter's report to share if you are interested. I would think some of the weaknesses would be similar in kids with the same symptoms.
