Hypoglycemia Episodes May Not Damage Brain

In one major study, Harvard University researchers concluded that repeated bouts of hypoglycemia may not result in long-term cognitive weakening. The study was based on an 18-year tracking survey of more than 1,000 diabetic adults.

Over the course of the study, about a third of patients reported regular bouts of hypoglycemia, or low blood sugar, which were sometimes serious enough to result in loss of consciousness or seizures. In the vast majority of cases, researchers found that hypoglycemic episodes were not related to any changes in brain function. However, researchers affirmed past studies that warned that extremely severe and prolonged hypoglycemia can lead to permanent cognitive impairment.
