糖尿病患者血糖波动异常与认知功能障碍关系的研究进展.

Diabetes can not only cause pathological changes in both large vessels and microvessels, but also accelerate the occurrence and development of cognitive dysfunction, increasing the risk of dementia. Studies have shown that diabetes-induced cognitive dysfunction is associated with elevated blood glucose and abnormal glucose fluctuation, and its pathogenesis is closely related to insulin resistance, oxidative stress, cerebrovascular lesions, inflammatory damage, brain cell apoptosis, as well as amyloid 卩-protein accumulation. At present, drug therapy for diabetic patients with cognitive dysfunction is still in the exploratory stage. It has been found that some hypoglycemic drugs, such as glucagon like peptide -1 receptor agonist, can improve cognitive dysfunction in these patients. However, it still needs to be further clarified by randomized controlled trails with large sample size. This article reviews the assessment methods of cognitive dysfunction, the effects of abnormal glucose fluctuation on cognitive dysfunction, and the pathophysiological mechanisms involved, as well as the effects of different hypoglycemic agents on cognitive dysfunction in patients with diabetes.
