New research has established a link between diabetes and long-term cognitive decline, following a correlation between blood sugar levels and brain function.
This study found that worse controls of blood sugar levels - regardless of whether someone is diabetic or not - could lead to a decline in brain function later in life.
The study, published in the Diabetologia journal with scientists from the School of Public Health Imperial College London and Peking University Clinical Research institute, discovered that a higher level of glycated haemogloblin could result in a higher rate of decline in memory, executive function and cognitive function.
"Our study provides evidence to support the association of diabetes with subsequent cognitive decline," researcher Dr Wuxiang Xie said.
"Our findings suggest that interventions that delay diabetes onset, as well as management strategies for blood sugar control, might help alleviate the progression of subsequent cognitive decline over the long term."
