I'm sorry hon, I'm no expert, the mind is still a complex mystery and that question is probably not yet answerable. I've heard of people whose minds stays young due to a learning disability, chemistry, mental retardation, or t.b.i., but you come across as with all your mental faculties intact and with intelligence. I believe anything is possible when it comes to the brain, so I bet how you feel, you are most likely not alone. I hope that you find your answers, and if you do, please post your findings here.
