Does computerized cognitive training improve diabetes self-management and cognition? A randomized control trial of middle-aged and older veterans with type 2 diabetes
Authors' conclusion
The adaptive computerized cognitive training was not substantially better than non-adaptive, but may improve memory. Post-hoc results for the combined arms suggest computer-related activities may improve diabetes self-management and other outcomes for middle-aged and older patients with type 2 diabetes. Practice effects or awareness of being studied cannot be ruled out.
Study context
- Population
- Veterans without dementia aged 55+ with T2D, Bronx, NY and Ann Arbor, MI90 per arm
- Participants
- 90 vs 90
- Comparison
- Adaptive vs non-adaptive computerized cognitive training
- Adaptiven = 90
- Non-adaptiven = 90reference
- Primary endpoint
- Diabetes self-management, improvement from baseline in the adaptive arm
- Follow-up
- 6 months post-intervention

Primary result
As reported in the abstract
Diabetes self-management
- Contrary to the hypothesis, adaptive arm did not show more improvement in self-management than non-adaptive (only memory did)
- Intention-to-treat analysis
- Linear mixed model analyses
Secondary outcomes
| Outcome | P value |
|---|---|
| MemoryMore improvement in adaptive arm | P < 0.01 |
Self-management, arms combined (post-hoc) · six-months post-intervention
- Self-management improved
- P < 0.001
- Post-hoc analysis
Other outcomes, arms combined (post-hoc)
- Memory, executive functions/attention, prospective memory, diastolic and systolic blood pressure improved
- P < 0.05
- HbA1c and medication adherence did not improve significantly
- Post-hoc analysis
