Advanced neuroimaging findings provided insights into the neurobiological underpinnings of PMDD. However, the role of the glymphatic system and hypothalamus\u2010related functional connectivity (FC) remains unclear. We aimed to investigate the abnormalities of glymphatic system and hypothalamus\u2010related FC in PMDD patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this study, 23 PMDD patients and 27 healthy controls (HCs) underwent diffusion tensor imaging (DTI) and functional magnetic resonance imaging scan. The DTI along the perivascular space (DTI\u2010ALPS) indices were used as an indirect evaluation of glymphatic function. Altered hypothalamus\u2010related FC was detected between PMDD patients and HCs, and machine learning was performed to assess the classification performance of these FC abnormalities in distinguishing PMDD patients from HCs. Leave\u2010one\u2010out cross\u2010validation was used for modal validation. Classification accuracy and area under the receiver operating characteristic (ROC) curve were evaluated. Furthermore, the associations between DTI\u2010ALPS index, clinical features, and hypothalamus\u2010seeded FC were explored.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared to HCs, PMDD patients exhibited: (1) significantly higher value of left DTI\u2010ALPS index; (2) increased intrinsic connectivity between the hypothalamus and anterior\/middle cingulate cortex (ACC\/MCC), middle frontal cortex (MFC), orbitofrontal cortex (OFC), insula, inferior temporal cortex (ITC), inferior parietal lobe (IPL), caudate, lentiform nucleus, and thalamus. The right and mean DTI\u2010ALPS indices were positively correlated with the hypothalamus\u2010right ACC\/MCC FC in PMDD patients. Significantly positive correlations were observed between the hypothalamus\u2010right ITC FC and anxiety, depression scores, as well as between the hypothalamus\u2010bilateral lentiform nucleus FC and severity of symptoms in PMDD patients. Hypothalamus\u2010related FC showed superior discriminative ability in differentiating PMDD patients from HCs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The increased glymphatic system activity and hypothalamus\u2010related FC might be associated with the supersensitive reactivity of emotional processing in PMDD patients.
