Summary: New analysis reveals that elevated blood sugar ranges might hurt mind well being, even in folks with out diabetes. The examine confirmed decreased connectivity in mind networks linked to cognition, reminiscence, and emotion regulation, with stronger results in older adults and ladies.
Elevated blood sugar was additionally tied to decrease coronary heart charge variability, an indicator of mind well being. These findings underscore the significance of managing blood sugar by means of a nutritious diet, common train, and medical checkups to help each physique and mind well being.
Key Facts:
- High blood sugar reduces connectivity in mind networks important for cognition.
- Older adults and ladies confirmed stronger results from elevated blood sugar.
- Low coronary heart charge variability, linked to mind well being, correlated with greater blood sugar.

A examine by Baycrest discovered that prime blood sugar might impair mind well being even in folks with out diabetes.
While the hyperlink between blood sugar and mind well being is effectively documented in people dwelling with diabetes, Baycrest is the primary to look at this connection in folks with out this prognosis.
“Our outcomes present that even when somebody doesn’t have a diabetes prognosis, their blood sugar might already be excessive sufficient to be negatively impacting their mind well being,” stated Dr. Jean Chen, senior writer on the examine and Senior Scientist on the Rotman Research Institute, a part of the Baycrest Academy for Research and Education (BARE).
“Blood sugar exists on a spectrum – it isn’t a black and white categorization of wholesome or unhealthy.”
The examine, titled “The associations amongst glycemic management, coronary heart variability, and autonomic mind operate in wholesome people: Age- and sex-related variations,” was just lately printed within the journal Neurobiology of Aging and examined 146 wholesome adults aged 18 and older.
For every particular person, researchers analyzed blood sugar, mind exercise utilizing magnetic resonance imaging (MRI) scans and coronary heart charge variability by means of electrocardiogram (ECG) readings.
“The findings spotlight the significance of managing your blood sugar by means of nutritious diet and train, not solely in your physique but in addition in your mind,” stated Dr. Chen, who can be Baycrest’s Canada Research Chair in Neuroimaging of Aging and Professor of Biomedical Physics on the University of Toronto.
“It’s additionally vital to get common checkups and to work with a healthcare supplier, particularly when you’ve got been recognized with pre-diabetes.
Main examine findings
- Higher blood sugar was related to decreased connection in mind networks. These networks play an important function in all points of cognition together with reminiscence, consideration and emotion regulation.
- The impact was stronger in older adults, but it surely was current throughout all ages; older adults usually had greater blood sugar than youthful adults.
- The impact was additionally stronger in girls than in males.
- In addition, there was a hyperlink between greater blood sugar and decrease coronary heart charge variability – that’s, the beat-to-beat change in a person’s coronary heart charge. Previous analysis signifies that greater heart-rate variability is related to higher mind well being.
In future work, the researchers may additional examine easy methods to enhance mind operate by altering heart-rate variability, which is a neater goal for intervention than blood sugar, particularly in non-diabetic people.

“The associations among glycemic control, heart variability, and autonomic brain function in healthy individuals: Age- and sex-related differences” by Jean Chen et al. Neurobiology of Aging
Abstract
The associations amongst glycemic management, coronary heart variability, and autonomic mind operate in wholesome people: Age- and sex-related variations
Introduction
The function of this examine was to make clear the relationships between glycemia and performance of the autonomic nervous system (ANS), assessed by way of resting-state purposeful connectivity (FC) and heart-rate variability (HRV).
Methods
Data for this examine had been extracted from the Leipzig Study for Mind-Body-Emotion Interactions, together with 146 wholesome adults (114 younger, 32 older). Variables of curiosity had been glycated hemoglobin (HbA1c), resting-state FC within the salience facet of the central-autonomic (S-CAN) and salience community (SN) and HRV (RMSSD and high-frequency HRV (HF-HRV)).
Results
HbA1c was inversely correlated with FC within the S-CAN however not SN. HbA1c was inversely correlated with HRV. Both RMSSD and log(HF-HRV) had been correlated with FC within the S-CAN and SN. Age- (not sex-related) variations had been noticed within the Hb1Ac-FC associations (stronger in older adults) whereas sex- (not age-related) variations had been noticed within the HRV-FC (stronger in females).
Conclusions
These findings prolong the diabetes literature to wholesome adults in relating glycemia and mind operate. The age- and sex-related variations in these relationships spotlight the necessity to account for the potential results of age and intercourse in future investigations.
