Yes, I believe it is. I had a very difficult time reading and understanding the information I read. Because there wasn't a way to diagnose Dyslexia then, my mother had me memorize poems, bible passages, sort buttons, and play Pacman. All those things greatly helped.
My daughter had the some problems, she was diagnosed, although her school was unable to help. She went to an outside professional, along with sorting buttons and memorizing, she placed a blue transparency film over the words. This stopped the words from swimming around the page.
