=0.03), indicating improved executive function. No significant differences were found in attention or memory domains. Also, the HCT group exhibited improvements in psychological profiles. A home-based HCT program improved frontal executive function in CU older adults. The hybrid analog-digital design may help reduce digital barriers, support usability, and foster sustained participation. Larger trials with active controls, modality-specific comparators, and extended follow-up are warranted to confirm benefits and optimize delivery. Trial Registration: Clinical Research Information Service Identifier: KCT0007922.
Key findings
- =0.03), indicating improved executive function.
- No significant differences were found in attention or memory domains.
- Also, the HCT group exhibited improvements in psychological profiles.
- A home-based HCT program improved frontal executive function in CU older adults.
- The hybrid analog-digital design may help reduce digital barriers, support usability, and foster sustained participation.
Why it matters
This pilot randomized controlled trial found that a home-based hybrid cognitive training programme improved frontal executive function, with no significant differences in attention or memory. It suggests possible benefit for executive function, but it does not show that the training treats, cures or prevents Alzheimer's disease.
