Trial summary

Type 2 diabetes mellitus and dementia are two of the commonest and most disabling conditions worldwide, responsible for an enormous and growing burden of disease. There is increasing awareness that the two conditions are linked, with cognitive impairment (worsening memory, thinking, perception) common in patients type 2 diabetes, and a strong association between type 2 diabetes and Alzheimer’s disease, the most common form of dementia.  Better markers are needed for the prediction of cognitive decline in people with diabetes. Left ventricular hypertrophy (LVH) is an enlargement and thickening (hypertrophy) of the walls of the hearts main pumping chamber, which is common in type 2 diabetes. To date there have been no studies on the association between LVH and cognitive decline in type 2 diabetes. The purpose of this study is to establish whether people with type 2 diabetes and LVH have increased rates of brain volume changes and cognitive impairment. An understanding of whether LVH is contributing to cognitive decline will allow us to identify patients at particular risk.
