could lack of concentration be the cause of dpdr?

Just a question, I have very bad concentration and memory like many others. But sometimes I read story about people and they write very good and fluence. I always need to take so much time to write something, my concentration is so bad. Could it be that dpdr (for some people) can be caused by a lack of concetration, focus. Like people with low iq who take meds to concentrate, maybe I need to try some of those. Could ritalin work? I dont know im just thinking about every possible sollution for dp. Im so tired of not living.
