Area of Science:

  • Neurology
  • Neuropsychology
  • Digital Health

Background:

  • Cognitive impairment (CI) monitoring is crucial for multiple sclerosis (MS) patient management.
  • The Brain on Track (BoT) is a web-based tool for cognitive screening.
  • Validating BoT for MS cognitive assessment is needed.

Purpose of the Study:

  • Validate the Brain on Track (BoT) test for multiple sclerosis (MS) patients.
  • Assess BoT's ability to differentiate MS patients from controls.
  • Evaluate BoT's capacity to detect CI in MS patients.
  • Analyze BoT's correlation with standard cognitive tests and its reliability.

Main Methods:

  • Applied BoT to 30 MS patients and 30 matched controls.
  • Administered BoT in-clinic and remotely.
  • MS patients repeated BoT every 4 weeks for 3 months.
  • Correlated BoT with a baseline neuropsychological battery.

Main Results:

  • BoT demonstrated high reliability (Cronbach's alpha = 0.89).
  • Significant differences found between MS patients and controls (p < 0.01).
  • BoT detected CI in MS patients (p < 0.001) and correlated with standard tests, especially information processing speed.
  • High test-retest reliability for most subtests (>0.70).

Conclusions:

  • The Brain on Track (BoT) test exhibits strong neuropsychological validity in MS patients.
  • Supports the use of self-administered computerized cognitive tests for MS.
  • BoT is a reliable tool for monitoring cognitive function in MS.
