According to wikipedia, Dyslexia is a disorder in the development of literacy which generally occurs in children aged 7-8 years. Dyslexia can occur to anyone, including in children who have relatively high levels of intelligence.

There are two types of dyslexia, yaitudevelopmental dyslexsia (congenital) fundquired dyslexsia (acquired due to disorder or changes in the way the left brain reads). Developmental dyslexia is suffered throughout the life of the patient and is usually genetic. Some studies suggest that the disease is associated with gray area dysfunction in the brain. The dysfunction is related to changes in connectivity in the phonological (reading) area. Some of the earliest signs of congenital dyslexia are late speech, obscure and reversed articulation, difficulty learning the shape and sound of letters, confused between the concept of space and time, as well as the difficulty of digesting verbal, quick, and sequential instructions.
