I forgot to mention:
I read about Chronic traumatic encephalopathy from frequent injuries such as concussions from fainting. I've fainted since I was 9 and in June I had another concussion and pretty severe neck sprain from fainting & falling into the corner of my tiled tub.
I'm sure this has played a part in my cognitive problems.
so sorry your going throught all of that sure sounds like a lot to handle, i really wish i could give you a answer but i really dont know i am so sorry.
i do know they are going to have a dr start coming on here to answer questions like you have and am very thankful, so plz hang in with us and am sure the dr can help you out.
that sounds very scary, and i hope you get some answers. I just wanted to comment on one part, and that was mixing up words. I do not forget the meaning of words, but I do use some interchangeably (like your example of table and chair--If someone asked if you were going to sit on the table, would you have known that was wrong?) i will say Thanskgiving when i mean Christmas, football when I mean basketball, gazelle when i mean deer. i don't usually notice when i do that, and i get annoyed when my husband points it out - he knows what i meant. i have done this since my cardiac arrest 13 years ago
