In the United States, nearly 15% of all adults 18 years or older had diabetes in 2021, and more than 90% of them had type 2 diabetes. Worldwide, it is estimated that the prevalence of diabetes will drastically increase over the next 20 years, according to projections by the International Diabetes Federation.
Type 2 diabetes occurs when a person’s body can’t properly respond to insulin or develops insulin resistance. As the disease progresses, the pancreas produces less and less insulin.
Medical News Today regularly reports on peer-reviewed studies related to type 2 diabetes. In this article, we highlight key findings from two recent studies on the link between type 2 diabetes and brain health as well as experts’ perspectives on the significance of the findings and insights into type 2 diabetes prevention and management.
A study published August 2 in the journal JAMA Network Open suggests that an individual’s hemoglobin A1c (HbA1c) levels over time may be a key indicator in predicting dementia risk. The findings concluded that maintaining stable A1C levels in optimal ranges is linked to a decreased risk of developing Alzheimer’s disease and related dementias in older adults.
