Cognitive impairment is nowadays more and more recognized as an important feature of the multiple sclerosis (MS) disease which contributes largely to disability. Cognitive assessment using classical neuropsychological tests are poorly correlated with patient's complaints and daily functioning. Ecological evaluations, recent and innovative way to assess cognitive functions with the true impact of cognitive impairment in everyday daily life of patients. One goal of an ecological test could be to identify MS patients in whom cognitive impairment has a strong interaction with daily life. Different type of ecological evaluation have been recently proposed in MS, including assessment cognitive tasks in a virtual reality environment using the Urban DailyCog® software developed in our laboratory (Hamel et al, 2015). Virtual reality environment assessments are promising in detecting cognitive impairment while providing friendly assessments for patients and simulating daily activities. . Cognitive dysfunction is correlated with white matter diffuse injury in relapsing-remitting MS (RRMS) patients and brain atrophy However, the relationships between structural brain damage and brain connectivity with cognitive functioning assessed by ecological evaluation are also unknown. The use of new techniques for morphological and functional MRI can study the contribution of diffuse white matter (WM) alteration and diffuse gray matter (GM) alterations in cognitive impairment and on their evolution.
The objectives are to evaluate the ecological assessment (Urban DailyCog® and actual reality) to detect cognitive impairment in everyday daily life of patients and their changes and to investigate structural WM and GM damages and the dynamic of functional connectivity for explaining and predicting cognitive disability during two years in RRMS patients treated by the same treatment Aubagio®.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Change of composite z ecological score based on individual ecological scores.
The composite z ecological score is the average of z ecological scores of virtual reality task (Urban DailyCog©) and actual reality tests. Z-scores will be calculated for each cognitive score with the following formula: (patient's score - mean value of HC group matched for age, sex, and education level)/standard deviation of the matched HC for each evaluation time (baseline and 2 years).
Time frame: At baseline (day 0) and at 24 months from baseline
Change of composite z cognitive score based on individual neuropsychological scores
The composite z cognitive score is the average of z individual cognitive scores. The score from each cognitive test is transformed into z-scores. Z-scores will be calculated for each cognitive score with the following formula: (patient's score - mean value of HC group matched for age, sex, and education level)/standard deviation of the matched HC for each evaluation time. Individual neuropsychological scores included in composite z cognitive score : the Alertness subtest, the divided attention subtest and the visual-scanning subtest from the TAP, The Symbol-digit-modalities-test, the Paced-Auditory-Serial-Addition-Test 3s, reversed span, the Stroop test, the Verbal fluency, Trail Making test, the California Verbal memory learning test and the Brief visual memory test -revised.
Time frame: At baseline (day 0) and at 24 months from baseline
Correlation of composite z cognitive score and ecological score with MRI parameters reflecting grey and white matter integrity and anatomic/functional connectivity
The composite z cognitive score and the composite ecological score are the average of z individual cognitive and ecological scores. The score from each cognitive and ecological test is transformed into z-scores. Z-scores will be calculated for each cognitive score with the following formula: (patient's score - mean value of HC group matched for age, sex, and education level)/standard deviation of the matched HC for each evaluation time.
