| その他関連情報/Other related information | 本研究は糖尿病患者の血糖変動と認知機能の関連を解明することを目的とし、国立循環器病研究センター通院中の軽度認知障害(MCI)を認める高齢(65-85歳)2型糖尿病患者100名に、CGM(リブレPro)、認知機能試験(Montreal Cognitive Assessment、Alzheimer's Disease Assessment Scale)を登録時、1年後、2年後と縦断的に行い、得られた血糖変動指標と認知機能試験スコアの変化との関連を解析する。 | This is a prospective, single center, observational study to elucidate the relationships between glucose fluctuation and cognitive function. The observation period is 2 years and in this study glucose fluctuation assessed using continuous glucose monitoring (Libre Pro) and cognitive test (Montreal Cognitive Assessment and Alzheimer's Disease Assessment Scale) are evaluated at baseline, 1-year visit and 2-year visit in elderly patients (65-85 years) with type 2 diabetes mellitus (DM) showing mild cognitive impairment (MCI). The target number of enrolled patients was set at 100 subjects who regularly attended the outpatient diabetes clinic at National Cerebral and Cardiovascular Center in Japan. |
