      abstract     = {It remains unclear whether functional brain networks are
                      consistently altered in individuals with subjective
                      cognitive decline (SCD) of diverse ethnic and cultural
                      backgrounds and whether the network alterations are
                      associated with an amyloid burden.Cross-sectional
                      resting-state functional magnetic resonance imaging
                      connectivity (FC) and amyloid-positron emission tomography
                      (PET) data from the Chinese Sino Longitudinal Study on
                      Cognitive Decline and German DZNE Longitudinal Cognitive
                      Impairment and Dementia cohorts were analyzed.Limbic FC,
                      particularly hippocampal connectivity with right insula, was
                      consistently higher in SCD than in controls, and correlated
                      with SCD-plus features. Smaller SCD subcohorts with PET
                      showed inconsistent amyloid positivity rates and FC-amyloid
                      associations across cohorts.Our results suggest an early
                      adaptation of the limbic network in SCD, which may reflect
                      increased awareness of cognitive decline, irrespective of
                      amyloid pathology. Different amyloid positivity rates may
                      indicate a heterogeneous underlying etiology in Eastern and
                      Western SCD cohorts when applying current research criteria.
                      Future studies should identify culture-specific features to
                      enrich preclinical Alzheimer's disease in non-Western
                      populations.Common limbic hyperconnectivity across Chinese
                      and German subjective cognitive decline (SCD) cohorts was
                      observed. Limbic hyperconnectivity may reflect awareness of
                      cognition, irrespective of amyloid load. Further
                      cross-cultural harmonization of SCD regarding Alzheimer's
                      disease pathology is required.},
