[Characterization of language disorders in children with lead poisoning].
BACKGROUND
lead poisoning can have a negative impact on the neuropsychological functions, including language, due to the damage it causes to the development of the Central Nervous System.


OBJECTIVE
to verify the occurrence of language disorders in children who suffered from led poisoning and to verify the correlation between the lead concentration level in the blood and the language disorders presented by the children.


METHODS
language evaluation of 20 preschoolers, with lead concentration level in the blood above 10 microg/dl.


RESULTS
13 children presented language impairment involving only phonology or more than one language subsystem. The statistical analysis indicated that no correlation exists between the severity of the language impairment and the concentration levels of lead.


CONCLUSIONS
the number of children with language impairment indicates lead poisoning as a risk factor for the present alterations, even though other risk factors for language disorders were found and the absence of correlation between the investigated variables.
