ADHD inattentive type is sometimes hard to detect. Both my children have it, and it wasn't until my daughter was a Freshman that it even hit our radar. Since inattentive types rarely have behavioral issues (other than maybe forgetting, getting lost in thoughts, taking an inordinate amount of time to get things done or spacing out), the signs are easy to miss. With my daughter especially, she has good organizational strategies and can be very self - sufficient. But, when she started complaining about an inability to stay focused during class, while reading and even during some sports activities we took notice.

Here are some good books that provide excellent strategies to manage ADHD and executive functioning problems:

Understanding Girls with ADHD, by Kathleen G. Nadeau, Ph.D.,
ADD Women and Girls: Late Diagnosis, Little Treatment http://www.additudemag.com/adhd/article/1626.html

My son takes stimulant medication for his ADHD. The combination of ADHD and severe dyslexia is too much to handle alone. The medication makes a huge difference in the way he can focus and attend. We are not treating my daughter - although I often wonder if we should. We have hired an academic support tutor that has helped her with study skill strategies and she is on a 504 that gives her extra time, class notes and outlines for class lectures. This has made a huge difference.

Inattention is a misnomer - ADHD inattentive is actually a deficit in tuning out unimportant information. People with this type of ADHD are often able to hyper focus if the task is very interesting. This may be what you are seeing. APD (auditory processing disorder) can often look like ADHD. And, it is important to realize that the two conditions are often comormid.

Good luck!!
