Synopsis

Keywords: Brain Connectivity, fMRI, T2DMTo investigate the underlying neural mechanism of T2DM-related brain damage, the functional connectivity density (FCD) mapping method was used to examine the density distribution of whole-brain resting functional connectivity from 77 patients with T2DM under different cognitive states (with normal cognitive function, DMCN and mild cognitive impairment, DMCI) and 40 healthy controls (HCs). The decreased long-range FCD in the left superior temporal gyrus (STG) in DMCI patients and its correlation with Rey Auditory Verbal Learning Test (RAVLT) score in all T2DM patients, which suggested left STG may be involved in the neuropathology of auditory memory in T2DM patients.
