These alterations encompass cerebral atrophy, vascular damage, increased white matter hyperintensities, microbleeds, a reduction in gray matter volume in the cerebellar cortex, modifications to the structure of the cerebellar dentate nucleus, and frontal cortex damage. Moreover, it may result in neuronal apoptosis and injury, a decline in the generation and maturation of neurons, disrupted or weakened neuronal autophagy, among other consequences. Investigators are employing sophisticated methods such as diffusion tensor imaging, diffusion kurtosis imaging, resting-state functional magnetic resonance imaging, cerebral blood flow examinations, and voxel-based morphometry to investigate these affected brain areas.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The pathogenesis of T2DM-related cognitive dysfunction is not fully understood.
