Abstract


Background: Assessing disparity in IQ is important in selecting an occupation and thus helping people lead a productive life. In Turner syndrome patients, this shall be more important as assessment of verbal IQ- and performance IQ disparity could be used in helping them select an occupation so that productivity and quality of life is not grossly compromised.

Methods: Based on karyotyping, 30 patients with turner syndrome and 30 patients with primary amenorrhoea due to other aetiologies were selected for the study. Cytogenetic analysis was done for every case using G-banding technique. Assessment of intellectual functions was done using Wechsler Adult Intelligence Scale (WAIS).

Results: Mean value of PIQ of X0 (turner) was 74.67 and that of XX (other amenorrhoea patients) was 90.30. Mean value of VIQ of X0 (turner) was 93.67 and that of XX (other amenorrhoea patients) was 93.60. Mean value of VIQ and PIQ disparity of X0 (turner) was 18.67 and that of XX (other amenorrhoea patients) was 3.

Conclusions: Turner syndrome patients have high VIQ-PIQ disparity when compared to other primary amenorrhoea patients.
