Dyslexia

The word 'dyslexia' comes from the Greek and means 'difficulty with words'. The British Dyslexia Association suggests that around 4% of the population is severely dyslexic and a further 6% have mild to moderate problems.

Dyslexia is one of the most common learning disabilities. It can vary in severity from person to person and can range from minor difficulties with spelling to severe problems with reading itself.

People with dyslexia often have normal (or above average) intelligence, yet perform below that ability in reading and writing tasks than in non-reading tasks. They have difficulty processing language, and in particular in the use, meaning, spelling and pronunciation of words.

Dyslexia is more common in males than females. It tends to be genetic (run in families) and continue into adult life.
