Cognitive Impairment and Dementia in Type 2 Diabetes Mellitus

Diabetes mellitus affects millions of people, causing many complications. Recent studies have shown a link between diabetes and mild cognitive impairment (CI) in persons with earlier onset and greater severity of diabetes. Although the pathophysiology of CI is multifactorial, there is stronger evidence that lack of glycemic control resulting in hypo- or hyperglycemia leads to CI among diabetic patients. With a growing geriatric population and increasing obesity trends in America, the prevalence of diabetes and the related CI, caregiving could be a challenge. Understanding the predisposing factors and the link between diabetes and CI or dementia can help improve the quality of life of diabetic individuals.
