| dc.description.abstract | Purpose: In recent years evidence of an association between bipolar disorder (BD), and specific neuropsychological impairment and familial transmission of BD has been mounting. The aim of this study was to identify the clinical and neuropsychological features of BD in adolescents, to assess the clinical and neuropsychological parameters in adolescents with a high risk of familial transmission of BD, and to identify probable early markers of the disorder. Materials and Methods: The study included 25 patients aged 12-18 years that were diagnosed as BD (case group), 25 adolescents without a mood disorder that had a parent and/or sibling diagnosed as BD, (risk group), and 25 typically developing adolescents (control group). To determine neuropsychological profiles the participants were administered the Wisconsin Card Sorting Test (WCST), Stroop Color Word Test (SCWT), and Continuous Performance Test (CPT), and to evaluate clinical and behavioral profiles the Children's Depression Inventory (CDI), Parent-Young Mania Rating Scale (P-YMRS), Youth Self-Report (YSR), and Conners' Parent Rating Scale (CPRS-48) were administered. Results: The case group performed significantly lower on the WCST, SCWT, and CPT in terms of executive and attention functions, whereas there wasn't a difference between the risk group and control group. In addition, significantly more of the adolescents in the case and risk groups had clinical and behavioral problems than those in the control group. Conclusion: The findings show that behavioral and clinical problems were more common in the risk group than in the control group, and that the frequency of attention and executive function impairment was similar in both of those groups. The findings suggest that BD itself may be associated with attention and executive function impairments, whereas a familial risk of BD may be associated with some behavioral problems. Follow-up and neuroimaging studies conducted with a larger number of participants, and neuropsychological test profiles may provide more detailed information about the neuropsychological profiles of individuals with a genetic risk for BD and may provide descriptive data about where and how the biological and psychometric deterioration initiate. | en_US |
