[Language and neurodevelopmental disorders. A review of their clinical characteristics].
BACKGROUND
Language is a keystone in the normal social and cognitive development of any group of children and early, fitting interventions can largely reduce the repercussions that the deficit has in this area. The article analyses the definition of language as 'the result of a complex nervous activity that allows individuals to communicate mental states by the production of multi-modal signs that symbolise these states in accordance with a linguistic community's own convention'. Other language-related terms are also dealt with.


METHODS
Different classifications of language disorders are also discussed and we analyse its characteristics in different neurological disorders, such as motor disorders with a central origin, autistic spectrum, learning disorders, mental retardation, and attention deficit and disruptive behaviour disorders.


CONCLUSIONS
Disorders affecting language clearly display semiological heterogeneity, and therefore it is advisable to take into account the classifications and terms related to it. It is also necessary to be familiar with the specific features of each alteration in the different neurological disorders so as to be able to reach an accurate diagnosis that allows the implementation of suitable lines of behaviour and interventions. Additionally, this will also allow timely measures to be taken in order to avoid later complications.
