Page "Dyslexia" Paragraph 9

Some early symptoms that correlate with a later diagnosis of dyslexia include delays in speech, letter reversal or mirror writing, and being easily distracted by background noise.

At later ages symptoms can include a difficulty identifying or generating rhyming words, or counting syllables in words ( phonological awareness ), a difficulty segmenting words into individual sounds, or blending sounds to make words, a difficulty with word retrieval or naming problems, commonly very poor spelling which has been called dysorthographia ( orthographic coding ), and tendencies to omit or add letters or words when writing and reading are considered classic signs.

Other classic signs for teenagers and adults with dyslexia include trouble with summarizing a story, memorizing, reading aloud, and learning a foreign language.
