MSReactor offers a scalable, reliable tool for monitoring cognitive function in multiple sclerosis (MS) remotely. This web-based battery effectively tracks subtle cognitive changes, aiding in disease progression assessment.
Area of Science:
- Neuroscience
- Clinical Psychology
Background:
- Current multiple sclerosis (MS) cognitive tests are resource-intensive and limited by practice effects, hindering frequent retesting.
- There is a critical need for brief, reliable monitoring tools to detect subtle, subclinical cognitive changes in MS patients.
- Longitudinal cognitive monitoring could redefine disease progression, complementing existing clinical assessments.
Purpose of the Study:
- To evaluate MSReactor, a web-based cognitive testing battery, for its reliability, validity, and feasibility in monitoring cognitive function in people with MS.
- To assess the correlation of MSReactor with established cognitive tests and its sensitivity to MS-related cognitive changes.
- To determine the acceptability and practice effects associated with MSReactor, particularly for remote home-based testing.
Main Methods:
- MSReactor, a web-based battery, was used to measure psychomotor speed, visual attention, and working memory via simple reaction time tasks.
- Participants completed clinic-based assessments at baseline and semi-annually, with remote home testing conducted quarterly.
- Acceptability, quality of life, depression, and anxiety were assessed alongside correlations with the Symbol Digit Modalities Test (SDMT), practice effects, and test-retest reliability.
Main Results:
- A cohort of 450 MS patients was recruited, with 81% engaging in home-based testing, demonstrating high adherence.
- The MSReactor tasks showed high participant acceptability (96% willing to repeat) and minimal anxiety reported.
- Practice effects stabilized within three tests, and MSReactor performance correlated with SDMT scores, with MS patients performing slower than controls.
Conclusions:
- MSReactor is a scalable and reliable cognitive screening tool suitable for both clinic and remote use in multiple sclerosis management.
- The tool demonstrated correlation with a validated cognitive test and sensitivity to MS, identifying baseline predictors of cognitive performance.
- MSReactor facilitates frequent, accessible cognitive monitoring, supporting early detection of changes and potentially refining disease progression assessment.
