Risk of cognitive deficits due to oxidative stress in type 2 diabetes

Data presented at the ANZSGM conference showed that patients with type 2 diabetes were likely to have a greater number of infarcts and smaller hippocampal and grey matter volumes on MRI compared to people without diabetes.

In addition, neuropsychological testing showed that type 2 diabetes was associated with poorer visuospatial function and planning function, the conference was told. 

The reduction in brain volume could be partially due to oxidative distress, said research leader Associate Professor Velandai Srikanth, the head of the vascular brain ageing division of stroke and ageing research at Monash
