There is talk of language delay when the emergence and development of speech and language in children are more delayed than usual, considering his age. Generally, this delay occurs at various levels of language, especially in the expressive and syntactic. The delayed speech has no clear origin, since it appears in children who do not have any intellectual, sensory or motor disorder, so it is not related to any pathology. However, the causes that can cause a child to suffer this delay in language usually due to emotional, cultural or hereditary factors. Anyway, it is necessary to diagnose whether this type of dysfunctions are observed from two years of age, when children have already started learning. Other manifestations that accompany the language delay are: psycho and relationship with other children, school learning difficulties, delayed oral and written expression and difficulty in learning to read problems.
