Hyperlexia They are extremely good at decoding language and thus often become very early readers. Some hyperlexic children learn to spell long words (such as "elephant") before they are two years old and learn to read whole sentences before they turn three. An fMRI study of a single child showed that hyperlexia may be the neurological opposite of dyslexia. The word hyperlexia is derived from the Greek terms "hyper" ("over") and "léxis" ("diction", "word"). Although hyperlexic children usually learn to read in a non-communicative way, several studies have shown that they can acquire reading comprehension and communicative language after the onset
Reading disability (e.g. attention-deficit/hyperactivity disorder, math disability, etc.). Although not an intellectual disability, it is considered both a learning disability and a reading disability. Dyslexia and IQ are not interrelated, since reading and cognition develop independently in individuals who have dyslexia."Nerve problems can cause damage to the control of eye muscles which can also cause diplopia" (WEBMD, 2005) Hyperlexic children are characterized by word-reading ability well above what would be expected given their ages and IQs. Hyperlexia can be viewed as a superability in which word recognition ability goes far above expected levels of skill. However, in spite of few problems with
