Elevated hippocampal copper in cases of type 2 diabetes.

ABSTRACT:

Background

Type-2 diabetes (T2D) is characterized by chronic hyperglycaemia and glucose-evoked organ damage, and displays systemic copper overload, elevated risk of impaired cognitive function, and epidemiological links to sporadic Alzheimer's disease (sAD). Contrastingly, sAD exhibits impaired cerebral-glucose uptake, elevation of cerebral glucose but not blood glucose levels, and widespread cerebral-copper deficiency. We hypothesized that sAD-like brain-metal perturbations would occur in T2D.

Methods

We measured nine essential elements in an observational case-control study of T2D without dementia (6 cases and 6 controls) in four brain regions and compared the results with those from our study of brain metals in sAD (9 cases and 9 controls), which employed equivalent analy
