For these with diabetes, sustaining wholesome blood sugar ranges helps to stop critical problems, like kidney issues and blindness — nevertheless it may also be vital for mind well being.
“The collective information on blood glucose and its results on cognitive well being, in addition to on dementia, proceed to quickly develop,” mentioned Dr. Michael S. Okun, medical advisor to the Parkinson’s Basis and director of the Fixel Institute for Neurological Illnesses on the College of Florida.
A latest U.Okay. research revealed in Journal of Diabetes Science and Know-how means that sporting steady glucose screens (CGMs) might decrease the danger of dementia.
DIABETES, HEART DISEASE CASES SKYROCKET — AND SCIENTISTS SUGGEST A KEY REASON
“Not solely does steady monitoring enhance glucose ranges within the blood and stop [low blood sugars], however we’ve additionally discovered that the availability of a gradual provide of glucose will improve mind operate,” he advised Fox Information Digital.
What to find out about steady glucose screens
CGMs are wearable medical gadgets within the type of a patch on the arm. A built-in sensor tracks sugar ranges and sends the outcomes to a smartphone, in accordance with GoodRx.

Diabetics who use CGMs now not should prick their fingers a number of instances a day to get their sugar readings earlier than meals and at bedtime.
These screens are extensively used amongst folks with diabetes – particularly these with sort 1 diabetes who’re on insulin, specialists say.
