I am by no means a doctor. I did ask a neurologist, some years ago, if a concussion could cause ADHD. His reply was that a concussion would not cause ADHD, however a concussion can cause ADHD symptoms to become mormore apparent. Hope this helps.
Remember our brain in neuroelastic, it might taktake time but your brain will heal from the concussion. Trust me.
I am on recovery from a 3 concussion #PostConcussionMom
