Abstract:

Hyperglycemia is an independent risk factor for cognitive dysfunction and may accelerate the progression of mild cognitive impairment to dementia. Diabetes mellitus is one of the most serious public health problems in the 21st century around the world. With the number of diabetic patients increased, more attention has been paid to type 2 diabetes mellitus related cognitive dysfunction. The type 2 diabetes mellitus related cognitive dysfunction mainly displays in the memory, attention, information processing speed and executive functions, etc.. Magnetic resonance imaging (MRI) studies have shown that, compared with patients without diabetes, type 2 diabetes mellitus patients can be present more often with the reduction of the brain volume, the incidence of lacunar cerebral infarction, the loss of cerebral white matter fiber tracts integrity, and the diminishment of brain activation function, the decline of brain function of interval nuclear structure connection, and the change of the cerebral metabolic material level.

Key words: Type 2 diabetes mellitus, Cognitive impairment, Magnetic resonance imaging
