I have had a head injury and post concussion syndrome which resulted in me losing my ability to read, which was incredibly frustrating and actually pretty frightening as someone who wrote as an editor/magazine journalist for a living.
I love words, books and creative writing, and was an above average avid reader, devouring books as a child. Now, I actually find it very hard to sustain any length of time reading long prose, and sadly if I tried to read a novel in one sitting, it'd be impossible.
I just don't have the reading stamina any more, which is something that devastated me a lot when it first happened. I still feel depressed about how I lost my mind's eye, when I banged my head too, which was an integral part of me enjoying reading.
I have to say, my alexia (loss of reading ability) was one of the most difficult things to deal with, and I'd literally give anything to turn back time and not have a head injury. My degree involved a lot of reading too, and I'd never be able to do it as well now.
Reading is such a key skill and to lose it is absolutely awful. If you enjoy reading, I salute you.
