It runs throughout our family. I have learned hundreds and hundred of "compensations" i.e. a lower-case "b" and "d" confused me so much that I would put the upright staff through the middle of the "o" so the letter could be "interpreted" by the reader as either one. Then when I was about age 35 a dyslexic child told me, "it's easy, you can spell the word BED can't you "B".."E".."D"....the up part of the letters make the head and foot boards....bed....I am VERY VERY VERY happy to be dyslexic. As far as I am concerned it is a "gift" that allows me to veiw the world, its problems and solutions, differently.
My brothers and father and I didn't have a name for it until the 1980's.
