I have been having cognitive problems due to multiple concussions. I didn't recognize the symptoms for what they were for many months, because a lot of them just seemed like worsening ADHD symptoms. I felt like I was going nuts! ADHD symptoms aren't supposed to get worse like that, so I was afraid I was getting prematurely senile or just losing my mind! I probably never would have gone back to the doctor and figured it out if I hadn't crashed my husband's car due to extreme spaciness (another concussion) and been confronted by him about changes he'd seen in me. Has anyone else been in this boat? Any thoughts or advice? Thanks!
