- 探索这种组合对认知功能和神经生物学标记物的有效性.
- 为大规模随机临床试验奠定基础.
主要方法:
- 一个随机,双盲,安慰剂控制的可行性试验,涉及80名年龄大于60岁的参与者,患有MetS和MCI.
- 四个治疗臂:INI/口服黄胺,鼻内安慰剂/口服黄胺,INI/口服安慰剂,鼻内安慰剂/口服安慰剂12个月.
- 通过易用性,坚持性和安全性评估可行性;通过认知测试和神经成像生物标志物评估有效性.
主要成果:
- 自2024年3月以来一直在进行数据收集;迄今为止有19名参与者随机选择.
- 选发现了满足MCI和MetS标准的挑战.
- 随机选择的参与者 (N=19) 年龄为~67岁,肥胖 (BMI 32.8),轻度认知障碍 (MMSE 25.0),并控制HbA1c (5.6%).
结论:
