Prediabetes and working memory in adults

27th Oct 2020

In a recent article in the British Neuroscience Association (BNA) journal, Brain and Neuroscience Advances, authors Gilda E. Ennis, Ursula Saelzler, Guillermo E. Umpierrez and Scott D. Moffatabout examined how glucose levels affect cognition and that prediabetes may increase the risk for cognitive decline. 

Prediabetes is a condition of intermediate hyperglycaemia that is highly prevalent in older adulthood. It's characterised by blood sugars that are higher than usual, putting a patient at high risk of developing type 2 diabetes

Looking at the effects of prediabetes on working memory

Nondiabetic older adults (≥ 65 years) who did not have dementia were tested to investigate if prediabetes was related to worse cognitive performance. Seventeen participants had normal glucose metabolism and 18 had prediabetes, as determined by World Health Organization criteria.

Four cognitive domains were examined across aspects of attention, thinking, and memory.

The prediabetes group performed similarly to the normal glucose metabolism group in three out of the four cognitive domains. However, the group did worse in a cognitive domain representing working memory - the ability to pay attention to, store and manipulate information for a brief period of time.

That prediabetes may worsen working memory in older adults deserves further investigation considering that the number of adults who have prediabetes increases from younger to older adulthood.
