Bipolar disorder (BD) is a complex psychiatric illness characterized by recurrent changes of mood, thought and behavior. Moreover, BD exhibits heterogeneous clinical features and variable degrees of cognitive deficits, which influence the patients' clinical and functional outcome. Therefore, over the last decades, sophisticated non-invasive brain imaging techniques have been increasingly employed to increase our understanding of the etiology of this disabling disorder. However, up until now, the results of structural and functional MRI studies on BD have been rather inconsistent, leaving the neurobiological determinants of this complex illness largely unknown. This chapter provides an overview of the most relevant findings from the Magnetic Resonance Imaging studies on BD. It will focus on both neuroanatomical alterations-in terms of gray matter volume and white matter diffusion-and neurofunctional deficits-linked to emotional processing-associated with BD. Overall, morpho-functional and connectivity evidence points towards the hypothesis that BD is a brain disorder characterized by deficits in selective brain networks, which may ultimately explain the specific clinical and cognitive alterations of this disabling disorder. Nonetheless, despite a tentative neurobiological model of BD has been delineated, the mechanisms underpinning this disorder have not been fully elucidated yet. Therefore, further research on biomarkers is needed in order to push the shift towards personalized medicine and more tailored pharmacological treatments.

Abstract
Bipolar disorder (BD) is a complex psychiatric illness characterized by recurrent changes of mood, thought and behavior. Moreover, BD exhibits heterogeneous clinical features and variable degrees of cognitive deficits, which influence the patients' clinical and functional outcome. Therefore, over the last decades, sophisticated non-invasive brain imaging techniques have been increasingly employed to increase our understanding of the etiology of this disabling disorder. However, up until now, the results of structural and functional MRI studies on BD have been rather inconsistent, leaving the neurobiological determinants of this complex illness largely unknown. This chapter provides an overview of the most relevant findings from the Magnetic Resonance Imaging studies on BD. It will focus on both neuroanatomical alterations-in terms of gray matter volume and white matter diffusion-and neurofunctional deficits-linked to emotional processing-associated with BD. Overall, morpho-functional and connectivity evidence points towards the hypothesis that BD is a brain disorder characterized by deficits in selective brain networks, which may ultimately explain the specific clinical and cognitive alterations of this disabling disorder. Nonetheless, despite a tentative neurobiological model of BD has been delineated, the mechanisms underpinning this disorder have not been fully elucidated yet. Therefore, further research on biomarkers is needed in order to push the shift towards personalized medicine and more tailored pharmacological treatments.File | Dimensione | Formato | |
