The goal of this randomized controlled trial is to compare the effectiveness of two innovative interventions aimed at preventing cognitive decline and work-related problems to enhanced usual care in improving quality of life in people with multiple sclerosis. Secondary objectives are: * to compare the effectiveness of the investigated interventions in improving cognitive, psychological, and work functioning, and in enhancing the brain's functional network * to examine which factors (i.e., baseline cognitive, psychological, work, and brain MRI-parameters) are predictive of the response to the investigated interventions * aim to qualitatively reflect on the process and outcome of the investigated interventions considering the perspectives of relevant stakeholders to allow for smooth and successful implementation in clinical practice Participants will follow the intervention for four months, with follow-up measurements at six months after intervention and 12 months after intervention.
Background Up to 65% of the people with multiple sclerosis (PwMS) develop cognitive deficits that severely affect daily life functioning and PwMS' quality of life. Moreover, approximately 65% of all patients end up unemployed within five years after diagnosis. Current treatments mostly focus on symptom management and return to work, which may be too late. It is hypothesized that timely interventions will help prevent or delay cognitive decline and work-related problems in PwMS, thereby improving quality of life. Objectives Primary Objective: To compare the effectiveness of the investigated interventions with enhanced usual care in improving quality of life. Secondary Objectives: 1. To compare the effectiveness of the investigated interventions in improving cognitive, psychological and work functioning, and in enhancing the brain's functional network. 2. To examine which factors (i.e. baseline cognitive, psychological, work and brain MRI-parameters) are predictive of the response to the investigated interventions. 3. To qualitatively reflect on the process and outcome of the investigated interventions considering the perspectives of relevant stakeholders to allow for smooth and successful implementation in clinical practice. 4. To compare the cost-effectiveness of the investigated interventions. Material and methods A randomized controlled trial with three arms and three follow-up visits over a total time period of 16 months. During these visits researchers will gather information from questionnaires, neuropsychological examination, MRI and blood sampling. All participants (N= 240) have a confirmed MS diagnosis according to the McDonald 2017 criteria, have subclinical cognitive impairment and are aged between 18 and 67. Participants will be randomly assigned to one of the three arms (N=90 in each arm). Interviews will be conducted with 12-15 participants from both interventions, 10-12 sport coaches, 8-12 work coaches and 10-12 supervisors from the workplace. 'Strengthening the brain' (4 month-program) consists of weekly 30 minutes 1-on-1 exercise and lifestyle coaching in combination with two moments per week unsupervised exercises at home and a home-based online computerized cognitive training. 'Strengthening the mind' (4 month-program) consists of biweekly contact with work coaches who are all diagnosed with MS themselves. 'Enhanced usual care' entails an appointment with a researcher in addition to usual care. Results The primary outcome is change in quality of life as measured with the 36-item Short Form. Several secondary outcomes will be collected: cognitive, psychological, cost-effectiveness, structural- and functional brain, neurological, physiological, and qualitative measures.

Lifestyle intervention containing physical exercise, lifestyle coaching, and cognitive training. The programme contains weekly 30 minutes 1-on-1 fitness and lifestyle coaching with two moments of exercise at home for 20 minutes. Online computerized cognitive training will be done for 60 minutes per week.
Work-focused intervention combining the capability approach and the participatory approach. Together with a work-coach who has been diagnosed with MS themselves, participants will assess important work values, discover challenges participants are facing, think of solutions for these challenges, develop a plan of action and implement these solutions.

RECRUITINGQuality of Life
Quality of life assessed using the 36-item Short Form. Item-scores are summed and transformed into a total score that ranges 0-100. Higher score corresponds with better quality of life.
Time frame: Baseline, Month 4, Month 10, and Month 16
Information processing speed
Information processing speed is assessed using the Symbol Digit Modalities Test (SMDT). The total responses made in 90 seconds is administered. Higher amount of correct responses equals better information processing speed.

Direct recall on the CVLT-II will be administered using number of correctly remembered items over learning trials 1-5. Delayed recall on CVLT-II will be administered using number of correctly remembered items 20 minutes after learning trail 5. Maximum scores for direct recall, delayed recall, and recognition are set at 80, 16, and 44, respectively. Higher score equals better verbal learning and memory.
