Dyslexia is a hidden learning difficulty that primarily affects the skills involved in accurate and fluent word reading and spelling. It is a life-long, genetic condition that is thought to affect around 10% of the population. Dyslexia affects the way information is processed, stored and retrieved, with problems of memory, speed of processing, time perception, organisation and sequencing. Students with dyslexia tend to have difficulties in phonological awareness, verbal memory and verbal processing speed.
