I have to disagree with the previous person saying to not use concerta for a mild TBI(traumatic brain injury). As a prior personal user of recovery, learner/administrator to my ADHD daughter, the results of the cognitive improvements gained from concerta's use were validated to be beneficial. I was previously non-adhd prior to a severe-TBI and usage post-TBI was documented medically to benefit. Yes I will agree that rest is required to heal the damaged cells (concussion trauma) however after all initial traumas to the body, give the body what it needs to progress to restored functions, including vitamins, minerals AND concerta (which'll act like an electrical system lubricant-better flow & processing).
This is speaking from personal experience & medical research. Take it for whatever it helps you with.
