What is Dyslexia?
Dyslexia is a hidden disability thought to affect around 10% of the population, 4% severely. It is the most common of the Specific Learning Difficulties, a family of related conditions with considerable overlap or co-occurrence. Together these are believed to affect around 15% of people to a lesser or greater extent.
Specific Learning Difficulties (SpLDs) affect the way information is learned and processed. They are neurological (rather than psychological), usually hereditary and occur independently of intelligence. They include:
- Dyspraxia or Development Co-ordination Disorder
- Attention Deficit Disorder
Contrary to popular misconception, Dyslexia is not only about literacy, although weaknesses in literacy are often the most visible sign. Dyslexia affects the way information is processed, stored and retrieved, with problems of memory, speed of processing, time perception, organisation and sequencing.
