I'm wondering if anyone tested his ability to learn new languages (say from scratch) and compare it to how it used to be pre-medication? I've been diagnosed with ADD at 24 and I always wanted to learn more languages (advanced in 3 atm) but never really started doing anything toward this direction. Now when Concerta therapy starts I'll most likely finnaly get started and the simple question is: Do you learn "much" faster when on Methylphenidate (Concerta)? What's your dose?

Short version: Does concerta (Methylphenidate) speeds up learning of new languages?
