Reading disability.The most common learning disability. Of all students with specific learning disabilities, 70%-80% have deficits in reading. The term "dyslexia" is often used as a synonym for reading disability; however, many researchers assert that there are different types of reading disabilities, of which dyslexia is one. A reading disability can affect any part of the reading process, including difficulty with accurate and/or fluent word recognition, word decoding, reading rate, prosody (oral reading with expression), and reading comprehension. Before the term "dyslexia" came to prominence, this learning disability used to be known as "word blindness."
Common indicators of reading disability include difficulty with phonemic awareness -- the ability to break up words into their component sounds, and difficulty with matching letter combinations to specific sounds (sound-symbol correspondence). -wiki
