Savant syndrome can be caused by a brain injury. This is the acquired form.
My brain injury was a stroke. "Stroke" is specifically named in the video.
I got to wondering...just how much of this "savant syndrome" did I already have?
I played the above (Hungarian Rhapsody by Franz Liszt) at my first piano recital. I was 5 years old. I was already hearing the word "prodigy." So congenital or acquired savant syndrome becomes a question. I was in gifted classes growing up. I left high school when I was 16 years old. I had a Bachelor's degree when I was 19.
It was off to work then. Forget school. Real life beckoned. I got my M.A. while working two part-time jobs. I moved and had my first child. It had been full-time work and my children until now.
That stopped when I was hospitalized. I actually decided to use these other skills you see when I got out of the hospital. Namely it was just the memory and ability to learn at that time.
The writing thing that you see now has evolved to this. My writing is due to my ability to learn. So I wonder how much is acquired? It's not even there yet of diagnosing savant syndrome. Medical records still have me as unconscious...and that's a battle! I don't even know if savant syndrome is the proper disorder.
(Just because savant syndrome never occurred so low before, doesn't mean it can't now. Medicine has advanced.)
