[Language characterization in the X-fragile syndrome: a review study]

Abstract

Background: X-Fragile Syndrome.

Aim: To compile information about the language, cognitive and behavior alterations in the X-Fragile Syndrome, using the results of previously published studies and to present the standardized instruments used as testing materials.

Conclusion: studies used formal and informal testing to assess language. The results present variability regarding the linguistic deficits, which are influenced by the level of the cognitive deficit and behavior alterations. Alterations of the oral praxes and of speech articulation are also expected.
