Could having a brain injury cause you to have some gifts?

I have CP from birth. And, this is going to sound weird and maybe even fake, but I can read really really fast with 100% comprehension. Usually when people hear fast, they think like 1,000 wpm or something, which is for sure a good rate. But, I can read at 5,000-7,000 wpm. I look at the 1st and last letter of each line and that "counts" as reading it for some reason. I don't know if this works for "normal" people or is it some kind of gift. The thing is, with my CP I have a learning disability with memory and have to read things many times to remember it. But, reading slow never helped. It's like I remember just as well as 200wpm as I do at 6,000 wpm. I obviously understand what I am reading because I take "comprehension" test and score perfectly on them after 10-15 reads. I am just wondering if this is some kind of "gift" or is it normal to be able to read so fast and still comprehend. It's funny now because reading it 10-15 times at this rate is about that amount of times if takes to the average person to read it 1-3 times. WHich is awesome for me since I am going back to school.
