The researchers will use technology-assisted ambulatory assessment techniques to examine cognitive dysfunction in people with Multiple Sclerosis (MS). The researchers will determine if ambulatory assessments are sensitive to subtle declines in cognitive functioning. They will also explore the impact of modifiable factors, such as sleep, physical activity, mood, and somatic symptoms on cognitive function. These efforts will uncover behavioral and medical intervention methods. Finally, they will explore whether variability in cognitive functioning predicts short- and long-term changes in other patient-centered functional domains, social participation and physical functioning.

Change in Cognitive Function - Ambulatory measurement via Dot Memory Test
Reported in terms of Euclidian distance/error Cognition Covariates may include: age, sex, disease duration, Multiple Sclerosis (MS) subtype (relapsing vs. progressive subtypes combined), personality variables, and cognitive reserve (education plus scores on test of vocabulary).
Time frame: Baseline up to year 2
Change in Cognitive Function - Ambulatory measurement via Symbol Search Test
Reported in Reaction Time (milliseconds) Cognition Covariates may include: age, sex, disease duration, Multiple Sclerosis (MS) subtype (relapsing vs. progressive subtypes combined), personality variables, and cognitive reserve (education plus scores on test of vocabulary).
Time frame: Baseline up to year 2
Change in Cognitive Function - clinic-based neurocognitive measurement via NIH Toolbox Cognitive Battery
Test Battery reported in T-scores. Covariates may include: age, sex, disease duration, MS subtype (relapsing vs. progressive subtypes combined), personality variables, and cognitive reserve (education plus scores on test of vocabulary).
Time frame: Baseline up to year 2
Change in Cognitive Function - clinic-based neurocognitive measurement via Symbol Digit Modalities test
Covariates may include: age, sex, disease duration, MS subtype (relapsing vs. progressive subtypes combined), personality variables, and cognitive reserve (education plus scores on test of vocabulary). The score is the number of correct answers in 90 seconds. Higher scores indicates better attention and processing speed.
Time frame: Baseline up to year 2
Change in Cognitive Function - clinic-based neurocognitive measurement via Paced Auditory Serial Addition Test
Covariates may include: age, sex, disease duration, MS subtype (relapsing vs. progressive subtypes combined), personality variables, and cognitive reserve (education plus scores on test of vocabulary). The score range is 0-60 and higher numbers indicate better sustained attention, speed of information processing, and working memory.
Time frame: Baseline up to year 2
Change in Cognitive Function - clinic-based neurocognitive measurement via Rey Auditory Verbal Learning Test
Covariates may include: age, sex, disease duration, MS subtype (relapsing vs. progressive subtypes combined), personality variables, and cognitive reserve (education plus scores on test of vocabulary). The scores from the test represent the total immediate recall (over 5 learning trials), delayed recall, and recognition. Higher scores indicate better verbal learning and memory.
Time frame: Baseline up to year 2
