In a nutshell
This review examined the findings from studies which looked at the connection between low blood glucose levels and brain function.
Some background
Diabetics who experience hypoglycemia (dangerously low blood sugar levels) may have a higher risk of experiencing dementia. Dementia is a group of brain disorders, including memory changes and personality changes. Dementia generally affects elderly individuals. Diabetic patients who have dementia may also have a higher risk of experiencing low blood glucose (sugar) levels.
Methods & findings
This review examined the relationship between hypoglycemia and dementia. Five studies investigating the relationship between low blood glucose levels and brain function in diabetics were included. These studies included elderly diabetic patients over the age of 55. All diabetic patients were treated with glucose-lowering medication. The results of these five studies were combined and analyzed together.
Low blood glucose levels increased the risk of dementia by 68%. Dementia increased the risk of having low blood glucose levels by 61%.
The bottom line
This study concluded that low blood glucose levels can increase the risk of dementia. Likewise, dementia can also increase the risk of having low blood glucose levels. The authors suggested that treatment for elderly patients at risk of dementia be carefully monitored.
The fine print
This review pooled together results from individual studies. The measurements of low blood glucose levels and dementia therefore differed slightly between studies.
What’s next?
Consult your physician regarding the strategies which can be taken to prevent or treat low blood glucose levels.
