Dyslexia is a disorder that manifests as a difficulty in the distinction and memorization of letters or letter groups, lack of order and rhythm in the placement and bad structure of phrases. These symptoms make their first appearances in both reading and writing.
This disease can result from multiple causes, which may include neurophysiological factors, by a slower maturation of the nervous system or mental distress, caused by the pressures and stresses of the environment in which the child develops.
The development of this condition varies with each individual; in its various cases may be a bad lateralization. This factor is the process by which the child develops a preference or dominance of one side of his body on the other. In general, laterality is not established before 5 or 6, although in some cases may occur earlier.
Those who see little altered this process for some reason, tend to have problems of organization in the vision of space and language. Often children with dyslexia have some form of impaired motor skills, i.e. a general clumsiness of movements, which may look poor balance and poor knowledge of the body scheme.
Children who suffer from this disease usually suffer from lack of attention as a result of intellectual effort they have to do to overcome their specific perceptual difficulties. Dyslexia is usually diagnosed in a more concrete when children begin life in the school, where reading and writing abilities are affected and are quickly detected the first problems by teachers.
