The word 'dyslexia' comes from the Greek and means 'difficulty with words'.

It is a difference in the brain area that deals with language. It affects the under-lying skills that are needed for learning to read, write and spell. Brain imaging techniques show that dyslexic people process information differently.

Around 4% of the population is severely dyslexic. A further 6% have mild to moderate problems. Dyslexia occurs in people from all backgrounds and of all abilities, from people who cannot read to those with university degrees. Dyslexic people, of all ages, can learn effectively but often need a different approach.

Dyslexia is a puzzling mix of both difficulties and strengths. It varies in degree and from person to person. Dyslexic people often have distinctive talents as well as typical clusters of difficulties.
