Type 2 diabetes mellitus is increasingly common, and previously unrecognized complications are emerging; namely, cognitive impairment and dementia. The mechanisms that link these factors together are still unknown, but likely result from the interplay of several variables, including vascular change, poor glycemic control, inflammation, and hypothalamic pituitary adrenal overactivity. At present, it is still too early to propose best practices related to the management of diabetes-induced cognitive change. All things considered, however, patients should be aware that proper management of metabolic and vascular complications may minimize the adverse effects of type 2 diabetes on cognitive function and quality of life.
