Acute hyperglycemia (high blood glucose levels) is a common event among patients of type 1 and type 2 diabetes. According to a latest study, acute hyperglycemia is associated with mild cognitive dysfunction.
The researchers felt that the cognitive-motor slowing associated with hypoglycemia is well documented; the acute effects of hyperglycemia have not been studied extensively, despite patients’ reports of negative effects.
The study findings revealed that hyperglycemia resulted in increased errors and slower responses when performing basic verbal and mathematical tasks. These tasks plays an important role in numerous daily functions such as balancing checkbooks, calculating insulin dosing, and school and work performance. However, further research is needed to determine the impact of hyperglycemia-related cognitive disruption on the daily lives and functioning of individuals with type 1 and type 2 diabetes.
The studies also indicated that excessive carbohydrate loading before exams and any other cognitive-sensitive tasks intended to avoid the negative consequences of hypoglycemia may in fact be counter productive, if such actions lead to hyperglycemia. Instead, optimal cognitive functioning would be anticipated with optimal blood glucose control (5 – 14 mmol/L). The study authors concluded that acute hyperglycemia is not a benign event for many individuals with diabetes, but is associated with mild cognitive dysfunction.
For patients benefits they can be trained to both recognize and accurately interpret disruptions in cognitive performance. By this training they may better recognize hyperglycemia and will be able to take quick actions to treat it
