Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄45-80岁。 2.糖尿病前期或近期诊断的2型糖尿病患者。 糖尿病前期的诊断符合美国糖尿病协会的指南即:(i)空腹血糖水平在5.6 mmol/l至6.9 mmol/l之间,或;(ii)餐后后两小时(口服葡萄糖耐量试验)血葡萄糖水平在7.8 mmol/l至11 mmol/l之间,或;(iii)糖化血红蛋白在5.7%至6.4%之间。2型糖尿病的诊断标准基于美国糖尿病协会指南。 近期诊断的2型糖尿病患者要求在过去12个月内被内分泌医生诊断为2型糖尿病的,2型糖尿病的诊断符合以下情况之一:(i)空腹血糖水平>=7.0 mmol/l;(ii)挑战后2小时(口服葡萄糖耐量试验)血糖水平>=11.1 mmol/l或;(iii)HbA1c>=6.5%。 3.内有记忆力障碍(6个月内)主诉 4.患者意识清楚,能够自己或者在家人的帮助下配合完成检查操作、问卷调查、病史采集等。 5.同意参与本研究,签署知情同意书。

Inclusion criteria

1. Age 45-80 years old. 2. Patients with prediabetes or recently diagnosed type 2 diabetes. The diagnosis of prediabetes meets the American Diabetes Association guidelines as: (i) fasting blood glucose levels between 5.6 mmol/L and 6.9 mmol/L, or; (ii) blood glucose level between 7.8 mmol/L and 11 mmol/L two hours after a meal (oral glucose tolerance test), or; (iii) glycosylated hemoglobin between 5.7% and 6.4%. Diagnostic criteria for type 2 diabetes are based on American Diabetes Association guidelines. Patients with recently diagnosed type 2 diabetes who are required to have been diagnosed with type 2 diabetes by an endocrinologist within the past 12 months should be diagnosed with one of the following: (i) fasting blood glucose level >=7.0 mmol/l; (ii) blood glucose level 2 hours after challenge (oral glucose tolerance test) >=11.1 mmol/l or; (iii)HbA1c>=6.5%. 3. Complaints of memory impairment (within 6 months). 4. The patient is conscious and able to complete the examination operation, questionnaire survey, medical history collection, etc. by himself or with the help of his family. 5. Agree to participate in this study and sign the informed consent form.
