NCT05791994

Brief Summary

The main objective is to compare changes in information processing speed after 30 days of intervention in participants with a dysexecutive mild cognitive impairment (MCI) and receiving either cognitive stimulation by adapted visual exercises (Emeraude® software) or the broadcasting of a television program without cognitive stimulation. Secondary objectives are:

  • To compare, after 30 days of intervention, in participants with a dysexecutive MCI and receiving either cognitive stimulation by adapted visual exercises (Emeraude® software), or the broadcasting of a television program without cognitive stimulation :
  • changes in information processing speed of each subtest,
  • changes in cognitive performance,
  • changes in executive functions,
  • changes in walking performance.
  • To compare the quality of life, after 30 days of intervention, of participants with a dysexecutive MCI and receiving either cognitive stimulation by adapted visual exercises (Emeraude® software) or the broadcasting of a television program without cognitive stimulation.
  • In the "Intervention" group, to study correlations between changes in information processing speed index and the final level reached for each cognitive stimulation exercise.

Outcome Measures

Primary Outcomes (1)

  • Changes in information processing speed

    Changes in information processing speed is assessed by processing speed index

    Baseline and after 30 days of intervention

Secondary Outcomes (8)

  • Changes in information processing speed of each subtest

    Baseline and after 30 days of intervention

  • Changes in cognitive performance

    Baseline and after 30 days of intervention

  • Changes in executive functions (cognitive flexibility)

    Baseline and after 30 days of intervention

  • Changes in executive functions (cognitive inhibition)

    Baseline and after 30 days of intervention

  • Changes in executive functions (working memory updating)

    Baseline and after 30 days of intervention

  • +3 more secondary outcomes

Study Arms (2)

Intervention group

EXPERIMENTAL
Procedure: Visual cognitive stimulation exercises

Comparator group

ACTIVE COMPARATOR
Procedure: Broadcast of a television program

Interventions

Patients included in Intervention group will receive a 30-minute session of complex visual stimuli on a touch screen (3 10-minute exercises : saccade exercises, then pursuit exercises, then matching exercises) every other day for 30 days, with increasing difficulty of the exercises as the sessions progress.

Intervention group

Patients included in Comparator group will watch a 30-minute television program (Allô Docteurs) on a touch screen every other day for 30 days.

Comparator group

Data Sharing

IPD Sharing
Will share

Data will be shared upon reasonable request. Only de-identified data will be shared. Any data collected during the study may be shared. The protocol will be shared initially. Other documents may be shared at a later date upon request (e.g., the CRF to allow a collaborator to select the data they wish to access). The recipients of the data will be researchers. The data will be available for any purpose deemed relevant by the study investigator, based on a protocol provided by the requester, after verification of the obtaining of regulatory approvals, including the favorable opinion of an ethics committee.

Shared Documents
STUDY PROTOCOL
Time Frame
The data will be shared after signing a negotiated data transfer agreement ( data access agreement), for the duration specified in the agreement.
Access Criteria
The data will be made available via secure transfer (sharing platform approved by the university hospital: BlueFiles or Oodrive).
