Clinical Trial Summary

Hypertension is an risk factor for cognitive impairment. The primary objective of this study is to evaluate the efficacy of 12-week computerized cognitive training in people with hypertension and mild cognitive impairment. The researchers will further investigate the long-term effects of cognitive training by prolonging the intervention for 24 weeks among a randomly selected sub-group.

Description:

This study is a double-blinded, randomized controlled trial. A total of 200 hypertension patients with mild cognitive impairment will be recruited to participate in this study after screening. These patients will be randomized to two arms under masking. The intervention arm will receive multi-domain adaptive cognitive training using a tablet. The control arm will receive an active control treatment and use the same tablet to receive the cognitive training tasks with weak difficulty change. Both arms will receive the same intervention dosage for 12 weeks, 5 times a week, and 30 minutes per time. After the 12-week intervention, the intervention arm will be re-randomized into two groups. One group will stop their intervention at 12 weeks; the other group will continue to receive the multi-domain adaptive cognitive training till the 24-week follow-up assessment. The neuro-psychological assessment will be administered at baseline, 12-week, and 24-week assessments for all participants. The structural and functional MRI will be administered at baseline, 12 weeks, and 24 weeks to evaluate the effect of cognitive training on brain structure and function.

Intervention

Behavioral:
• Multi-domain adaptive cognitive training
The multi-domain adaptive cognitive training covers seven aspects of fundamental cognitive function, including sensory perception, cognitive flexibility, attention, memory, language, logic calculation, and emotion recognition and management. A self-adaptive algorithm is embedded in the tablet-based cognitive training platform, which will help deliver suitable tasks at the right difficulty level for each participant according to their personal profile and real-time performance. The intervention dosage is 30 minutes per time, 5 times a week.
• Basic cognitive training with no difficulty change
The basic cognitive training for the control arm will also be delivered via a tablet. The training tasks will be fixed at a primary difficulty level without adaptive algorithm. The intervention dosage is also 30 minutes per time, 5 times a week.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Global cognitive function change measured by BCAT in 12 weeks	The proportion of patients whose global cognitive function improves 0.67SD compared to the baseline cognitive function measured by Basic Cognitive Ability Test (BCAT). BCAT is a set of neuropsychological battery tests which was designed to measure global cognitive fucntion and cognitive function of sub-domains. Higher scores of BCAT means a better global cognitive function.	12 weeks after randomization
Secondary	Global cognitive function change measured by BCAT in 24 weeks	The proportion of patients whose global cognitive function improves 0.67SD compared to the baseline cognitive function at 24 weeks measured by Basic Cognitive Ability Test(BCAT).	24 weeks after randomization
Secondary	Sub-domain cognitive function improvement including memory, attention, and execution memory	The proportion of patients whose sub-domain cognitive function, including attention, memory, execution function improves measured by the individual capability test in BCAT.	12 weeks, 24 weeks after randomization
Secondary	Cognitive score change	Mean change from baseline in global cognitive function score measured by basic cognitive ability test (BCAT) at 12 weeks and 24 weeks.	12 weeks, 24 weeks after randomization
Secondary	Self-efficacy score	Mean change from baseline in self-efficacy score measured by the General Self-Efficacy Scale at 12 weeks, and 24 weeks	12 weeks, 24 weeks after randomization
Secondary	Quality of life score	Mean change from baseline in the patient's quality of life score measured by EQ-5D-3L at 12 weeks and 24 weeks.	12 weeks, 24 weeks after randomization
Secondary	Anxiety score	Mean change from baseline in the patient's anxiety score at 12 weeks and 24 weeks. Anxiety status will be measured by GAD-7 questionnaire. Higher score of GAD-7 scale represents more anxiety status.	12 weeks, 24 weeks after randomization
Secondary	Depression score	Mean change from baseline in the patient's depression score at 12 weeks and 24 weeks. Depression status will be measured by PHQ-9 questionnaire. Higher score of PHQ-9 scale represents more depression status.	12 weeks, 24 weeks after randomization
