Core Tip

Core tip: Diabetes mellitus increases the risk of cognitive impairment and dementia. Impairment of insulin signaling is a critically important factor and may be the cornerstone of the development of these cognitive sequences regardless of diabetic status. Therefore, anti-diabetic medications especially insulin therapy may have a significant role in the management of various cognitive and mental dysfunctions.
