On the cover: Patients with type 2 diabetes mellitus (T2DM) have a considerably high risk of developing dementia, especially for those with mild cognitive impairment (MCI). Investigation of the microstructural change of white matter between T2DM patients with amnesic MCI and T2DM patients with normal cognition can help to understand the brain variations in T2DM-related amnesic cognitive impairment. This image is of the right inferior fronto-occipital fasciculus and the right inferior longitudinal fasciculus correlations with episodic memory and attention function impairment in T2DM patients with amnesic MCI.
