SOTO-VEGA, Jorge Guillermo; GARCIA VALENCIA, Jenny; VARGAS, Cristian  and  LOPEZ-JARAMILLO, Carlos. Resting-state functional nuclear magnetic resonance imaging in patients with bipolar disorder: beyond euthymia. rev.colomb.psiquiatr. [online]. 2022, vol.51, n.2, pp.153-157.  Epub Aug 09, 2022. ISSN 0034-7450.


imaging in the resting state (R-fMRI) Functional nuclear magnetic allows the identification of complete functional connectivity networks and the possible resonance neuronal correlations of psychiatric disorders. The literature on R-fMRI and bipolar disorder (BD) will be reviewed, emphasising the findings in the phases of mania, hypomania and depression.


It is a narrative review of the literature in which articles were searched in PubMed and Embase, with the key words in English "bipolar disorder" AND "resting state", without limit on the date of publication.


The studies of BD patients in the mania and hypomania phases who underwent R-fMRI show concordant results in terms of decreased functional cerebral connectivity between the amygdala and some cortical regions, which indicates that this functional connection would have some implication in the normal affect regulation. Patients in the depressive phase show a decrease in functional brain connectivity, but as there are seve-ral anatomical structures involved and neural networks reported in the studies, it is not possible to compare them.


There is a decrease in functional connectivity in patients with BD, but current evidence does not allow establishing specific changes in specific functional brain connectivity networks. However, there are already some findings that show correlation with the patients' symptoms.
