I've had quite the number of concussions do to severe beatings from dear old dad, car accident, sports, and as a child I found it hard to pay attention when walking( I kept looking around at things) and wound up walking into things all the time.

I had a CT scan about 8yrs ago since I suffer from chronic migraines, but dr said everything was normal nothing stood out. I have a short attention span, an even shorter fuse, and have issues reading. I constantly get letters and number flipped.
