Klinefelter syndrome: a speech-language and neuropsychological assessment
Abstract
ABSTRACT The Klinefelter syndrome is a chromosomal aneuploidy caused by additional X chromosomes in men. The diagnosis is made by clinical observation and karyotype examination. Besides other characteristics, the phenotype involves infertility, hypogonadism, gynecomastia, and cognitive alterations, mainly in the language domain. This paper describes the case of a teenager with Klinefelter syndrome and history of difficulties in the learning process, behavioral and communication problems. The ethical guidelines were followed in the present report. The cognitive-communicative, pragmatic and syntactic profile was drawn from the speech and neuropsychological evaluations. The speech-language assessment showed deficits in expression and comprehension. Difficulties were also found in phonological awareness, mathematical operations, reading and writing, access to the lexicon, alterations in pragmatics and occasionally, in syntactics. The neuropsychological evaluation indicated impairments in tasks that require the identification of similarities, establishment of cause-effect relationships and analogies, demonstrating a compromised reasoning for logical operations, with intellectual level incompatible with the chronological age. This interdisciplinary clinical study favors intervention approaches in rehabilitation, to maximize the potential of the individuals affected, contributing to improve their quality of life.
