Brief Summary
Objective A growing body of evidence supports diabetes as a risk factor for cognitive decline. Diabetes is significantly associated with accelerated cognitive decline, poorer cognitive function, and mild cognitive impairment and dementia. Cognitive training is an effective intervention to improve cognitive function. However, the current cognitive training does not fully consider the different areas and degrees of cognitive function impairment of older adults. This study aims to evaluate the effect of adaptive cognitive training on cognitive function of older adults with hypertension in the community. Participants Age 60 years or older, diagnosis of diabetes, fasting blood glucose≥6.1mmol/L and cognitive function assessment showed no dementia. Design The study was designed as a double-blind randomized controlled trial. 120 diabetes participants without dementia aged 60 years or older in Shijingshan, Beijing and Haidian, Beijing were included. Participants will be randomized to adaptive cognitive training (intervention group) and placebo cognitive training (control group) at a ratio of 1:1. Both training will be delivered by using PADs with the same appearance. The interventions will last for 6 months and follow up to 12 months, and both groups will be followed up on the same time schedules for all outcome measurements. The primary outcome is changes in MoCA scores from baseline to post-intervention, 6 months. The current trial has been reviewed by the Ethics Committee of Plastic Surgery Hospital, Chinese Academy of Medical Sciences \& Peking Union Medical College (approval number: 2024-162).

Outcome Measures
Primary Outcomes (1)
Montreal Cognitive Assessment (MoCA)
MoCA has been widely used in the cognitive function assessment of middle-aged and elderly people in China, including executive function, memory, orientation, computation, conceptual thinking, visual perception, language, and attention. The MoCA scale scores ranged from 0 to 30, and the lower the score, the worse the cognitive function.

Study Arms (2)
adaptive cognitive training
EXPERIMENTALThe intervention lasted for 12 weeks. Participants will revieve 30 minutes of training per day, at least five days per week. In each task, once a high accuracy (e.g. \>80%) is achieved, the task is automatically upgraded to the next difficulty level.
placebo cognitive training
PLACEBO COMPARATORThe intervention lasted for 12 weeks. Participants will revieve 30 minutes of training per day, at least five days per week. The tasks will be set to a fixed level of difficulty.
Interventions
The intervention was computerized, multi-domain, adaptive cognitive training. Training areas include processing speed, attention, perception, long-term memory, working memory, computation, executive control, reasoning, and problem-solving. Embedded in the Adaptive Cognitive training application is an adaptive algorithm that will help provide each participant with a cognitive training task at the right level of difficulty based on their profile and real-time performance.
Participants received cognitive training tasks of fixed difficulty.
