Abstract [en]

Klinefelter syndrome (KS) is the most common sex chromosome disorder, which is caused by an extra X chromosome in males (47, XXY). Sixteen males (8 KS, 8 controls) with a mean age of 37.94 (SD = 7.38), and matched for education participated. The objective of the study was to examine whether group differences in cognitive performance between KS patients and healthy male controls existed. The participants received an extensive cognitive test battery on tasks assessing executive functioning/working memory, attention, cognitive speed, spatial ability, episodic memory, emotion identification and semantic memory. ANOVA analyses showed significant group differences in executive functioning/working memory. MANOVA analyses showed a significant group difference in audio attention. No group differences were found in spatial ability, cognitive speed, episodic memory, emotion identification, and semantic memory. The lack of group difference in episodic memory may suggest spared function.
