The term comes from Greek meaning “hard" and is characterized by a difficulty in the area of reading, writing and spelling, and it was first identified in 1881 by Berklan but the term 'dyslexia' was coined in 1887 by Rudolf Berlin, in Germany.

People with dyslexia have difficulties in the association of sound to the letter (the beginning of the alphabet); also tend to exchange letters, or even write them in reverse order.
These symptoms may coexist or be confused with the characteristics of various other factors of learning disabilities such as attention deficit hyperactivity disorder. Nevertheless dyslexia and disorders of attention and hyperactivity disorder are not correlated with development problems, and it can even occur to children’s with a intelligence Quotient (IQ) above average.

In the case of school-age child, the Psycholinguistics defines dyslexia as an unexpected failure in reading (dyslexia), writing (dysgraphia) and spelling (disortographia) provided the age at which these skills have to be automated. Is what we called of developmental dyslexia.

Is there any physical causes?
There isn’t a consensus among scientists about the causes of dyslexia; recent studies find strong evidence for neurological dyslexia. Several researchers have suggested a genetic origin. According to this approach dyslexia, is a condition that manifests itself throughout life with no cure. In some cases medication and compensation strategies help dyslexics to live and overcome their difficulties with written language.

Is it possible to identify some reading and writing mistakes?
* Errors due to confusion around particular:
* Confusion on the proximity and sequel of articulatory speech disorders:
The linguistic features, involving the skills of reading and writing, the most striking of dyslexic children are: the accumulation and persistence of their spelling errors when reading and spelling; confusion between letters, syllables or words with subtle differences in spelling; confusion between letters, syllables or words with similar spelling but with different orientation in space; confusion between letters that have a common point of articulation; partial or total inversion of syllables or words.

Are there any other learning disorders accompany the dyslexics?
Some times we can find changes in memory series, written language, difficulties in mathematics, Poverty vocabulary, Shortage of prior knowledge (long-term memory)

Can an adult be dyslexic?
In the case of adults, such difficulties may occur after a stroke accident (CVA) or brain trauma, when that happens we say that it is acquired dyslexia.

Can  it be treated, can they be successful in there life’s?
In case of dyslexia, the most appropriate treatment is thru the rehabilitation of the brain; meaning, by reaped exercises we try to transform the num automatic process of reading and writing in an automatic process. Usually dyslexic people can have a normal live, and they can be very successful. 

Examples of dyslexics that have been or still are successful in several different areas:
  • Agatha Christie
  • Alexander Pope
  • Albert Einstein
  • Charles Darwin
  • Cher (Singer)
