Attention Deficit Disorder and Attention Deficit Hyperactivity Disorder are behavioral disorders, not disorders of learning. In various studies as many as 50% of those diagnosed with a learning or reading difference have also been diagnosed with ADD/ADHD.
Although disabilities may co-occur, one is not the cause of the other.
That means that treatment for ADD/ADHD will not be effective as treatment for a learning disorder such as dyslexia.
And treatment for learning disorders doesn’t treat ADD.
However, if an individual is having trouble understanding something (learning disorder), he/she may appear to be inattentive. And an attention problem will get in the way of an individual’s ability to learn. So it’s tricky to manage, especially since ADD/ADHD can be difficult to diagnose.
