Hi,
I don't know much about AD/HD, but what my med specialist said to me was that once your mood improves from depression your concentration, focus and memory and attentionare also supposed to improve. If your concentration and attention does not improve once your mood improves, then it's possible that there is an underlying cause that is still hanging around. So, in my case my mood has GREATLY improved but my attention and concentration and memory are still in the toilet, thus suggesting that I be evaluated for AD/HD. Once that is either confirmed or denied then we will go from there....idk if this helps, but this is all I've got
