    The Reflection of Self-Esteem on the Brain Structure: A Voxel Based Morphometry Study in Healthy Young Adults
    (Turkish Neuropsychiatric Society, 2023) Erata, M.C.; Eroğlu, S.; Özkul, B.; Uslu, Ö.; Erdogan, Y.; Kitis, Ö.; Gönül, A.S.
    Introduction: Low self-esteem is a known risk factor for mental illnesses. Neuroimaging studies have identified evidence for a functional association between default mode network (DMN) and self-esteem levels. However, it is not clear whether there is a similar association between trait self-esteem and the structures composing DMN. This study aimed to investigate the relationship between the DMN associated brain structures and trait self-esteem. Methods: We obtained 3T structural magnetic resonance imaging (MRI) data of 75 healthy subjects and detected anatomical regions correlated with their Rosenberg Self-Esteem scores via voxel-based morphometry (VBM). Results: We found positive associations between self-esteem and regional grey matter volumes in the right temporoparietal junction/ inferior parietal lobule (BA 39), cortical midline regions at precuneus/ dorsal cingulate cortex (BA 31), rostral and dorsal anterior cingulate cortices (BA 32). Conclusion: The results of the current study support the fMRI studies suggesting self-esteem levels associated with DMN. Further neuroimaging studies should consider the functional and structural coupling of the default mode network during the execution of the functions related to self-esteem. © 2022 by Turkish Association of Neuropsychiatry-.
