Episodes of low blood sugar may put an older person at risk for dementia. Researchers followed nearly 800 patients with diabetes. They were at least 70 years old at the start of the study, which lasted for 12 years.
Those who needed to be treated for hypoglycemia had double the risk of developing dementia during that time. Hypoglycemia is severe low blood sugar and often results from aggressive treatment for diabetes. If too many medications are taken or the dose of diabetes drugs is not adjusted properly, hypoglycemia is a common complication of treatment. Guidelines have often encouraged physicians to lower blood sugar into a normal range. But such recommendations sometimes result in more hypoglycemic bouts.
The brain relies on glucose as its energy source. When blood sugar falls too low, it leads to cognitive impairment. This is a vicious cycle since people with dementia have a much harder time managing their diabetes appropriately. The take-home message of this new research is that aggressive diabetes management that leads to hypoglycemic episodes may do more harm than good.
