My mom has dyslexia. When i was little i dont think i showed any signs of dyslexia, i mean i would mess up some words occasionaly. Im in 8th grade & 14 and in all advaned classes & taking geometry honors. Recently i've noticed some words & letters getting mixed up when i read or write. the other day i was writing down a date (1968) and i wrote 1689 instead. I'm reading a book for a book report too and when i read sometimes the words look like they're moving or printed in a wave instead of a line. I can only read a few pages at a time or i'll start to get a headache. Is it possible for me to have dyslexia?
By the way i have not hit my head recently or anything.
