Sleeping,

I bet your borderline ADD diagnosis was just that. Mild ADD does not mean much. Many people have a variety of the symptoms that lead to a diagnosis of ADD. 10 years ago, it was the classic diagnosis for anybody who was not succeeding academically as expected.

The divided attention, easy distractability and other ADD like symptoms have different causes when caused by concussion. There are a myriad of work-arounds and other accommodations for dealing with focus and distractability. Stimulant medications can be counter to recovery. I would try many other things before ADD meds.

Besides, many with ADD/ADHD just have lazy brains that have not learned proper functioning. Our culture no longer allows brains to learn how to maintain focus because of media that over-rewards short attention and under-rewards developing good attention skills. The same techniques work with PCS and development caused ADD. Volitional qEEG based biofeedback can be helpful.

Either way, the question is, Where do you go from here?
