| Abstract | Executive dysfunction is common and impairing in youth bipolar disorder (BD), and oxidative stress (OS) and brain-derived neurotrophic factor (BDNF) have been implicated in executive deficits of adult BD. This study aimed to determine the association between OS and executive dysfunction in BD adolescents and the influence of BDNF on this association.Serum levels of lipid hydroperoxides (LPH) and 4-hydroxy-2-nonenal (4-HNE) and BDNF levels were measured in 29 BD and 25 control adolescents. The intra-extra-dimensional (IED) set-shifting task assessed executive function. Lower IED scores indicated better performance. High and low BDNF subgroups were defined by median split.IED Z-scores were impaired in the BD group compared to controls, whereas biomarker levels were not significantly different between groups. LPH-BDNF correlations were significantly different between BD and controls (Z = 2.046, p = 0.041). In high BDNF BD subjects, LPH was significantly positively correlated with IED completed stage trials (ρ = 0.755, p = 0.001) and pre-extra-dimensional shift errors (ρ = 0.588, p = 0.017). Correlations were opposite in controls. In a linear model, LPH, BDNF, and the LPH-BDNF interaction each significantly explained variance of IED total trials (adjusted) (model r 2 = 0.187, F = 2.811, p = 0.035).There is a negative association between LPH and executive function in BD adolescents, which may be modulated by BDNF. LPH and BDNF may be useful biomarkers of executive function in BD. These findings highlight the importance of examining multiple peripheral biomarkers in relation to cognitive functions in BD adolescents. Future studies should explore these factors in longitudinal designs to determine the directionality of observed associations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
