Background: Apart from classic phenotype there is a specific intellectual profile in patients with Turner syndrome (TS).
Objectives: The aim of the study was the assessment of intellectual functioning in patients with TS and the evaluation of the age, growth deficit and karyotype influence on the intellectual profile in this group.
Material and methods: 29 girls with TS were followed up and had the IQ measured by Wechsler test.
Results: There were lower results in subtests of non-verbal score but normal in full scale IQ and verbal IQ. We also affirmed the presence of disturbances in visual-spatial area, which were more intensive in older patients. We have observed no correlation between the degree of the growth deficit or the kind of karyotype and IQ test results.
Conclusions: The basic outcomes of our study are agreed with previous reports. In contrast to them we have not observed worse intellectual functioning in patients with 45,X karyotype and younger patients have had better visual-spatial organisation.
