Given that up to 70% of people with secondary progressive MS are cognitively impaired, the search for effective treatments is considered a priority by people living with the disease. This proposal will address the effectiveness of cognitive rehabilitation (CR) and exercise, either alone, or in combination in this regard. A team of MS researchers has been assembled from the USA, Canada, the United Kingdom, Italy, Denmark, Germany and Belgium for this. A total of 360 people with progressive MS will make up the sample. Brain MRIs will be undertaken in a third of the sample before and after the 12 weeks of treatment to document the functional changes that are expected to occur with symptom improvement.
Aim: The broad aim of this proposal is to evaluate a multidisciplinary and multi-modal approach to rehabilitation in people with progressive MS. Cognitive rehabilitation and aerobic exercise will be evaluated individually and in combinations to address cognitive dysfunction as the primary outcome variable.
Over 20 years have passed since the introduction of the first disease modifying treatment, interferon beta-1betaseron (b), for multiple sclerosis (MS).Since then 13 treatments have been approved and made it onto the market. All are for relapsing-remitting disease (RRMS), apart from mitoxantrone which is limited to progressive disease with relapses, Interferon-beta-1b, which is for secondary progressive disease (SPMS), but does not delay disability progression and Ocrelizumab for primary progressive MS only. Thus, for a sizeable proportion of people with MS there is no therapeutic option to slow progression. This raises the question, how are patients with primary and secondary progressive MS (PPMS and SPMS) to be helped? While research is underway to find a medication that holds promise of halting further deterioration in a disease that has already entered a progressive stage, patients and their clinicians are left with basically symptomatic treatments.
Hypothesis: The investigators hypothesize that CR and aerobic exercise are effective treatments for cognitive impairment (processing speed deficits) in people with progressive MS. In particular a combination of these two treatment given twice weekly over 12 weeks is more effective than each individual treatment given alone or as sham. The investigators further hypothesize that improvements in processing speed will be matched on functional MRI (fMRI) by enhanced neural activity in networks associated with information processing speed.

Change from baseline cognitive Information processing speed at 12 weeks and 6 months
The Symbol Digit Modalities Test (SDMT) will be used to measure cognitive information processing speed The SDMT is a simple matching task that requires the participant to refer to a reference key, in order to correctly match a geometric symbol with the corresponding number. Participant will be under a 90 second time constraint to quickly and correctly match each pair. Test will be administered at index assessment, 12 weeks following cognitive rehab/ aerobic exercise, and at 6 months to examine cognitive retention
Time frame: Baseline, 12 weeks, and 6 month
Change from baseline cognitive verbal memory at 12 weeks and 6 months
The California Verbal Learning Test (CVLT) will be used to measure verbal memory The CVLT test begins with the examiner reading a list of 16 words, participants are then instructed to report as many of the words as they can remember. After recall is recorded, the entire list is read again, altogether, there are five learning trials. Test will be administered at index assessment, 12 weeks following cognitive rehab/ aerobic exercise, and at 6 months to examine cognitive retention
Time frame: Baseline, 12 weeks, & 6 month
Change from baseline cognitive visual memory at 12 weeks and 6 months
The Brief Visuo-Spatial Memory Test (BVMT) will be used to measure visual memory Participants are presented with six abstract designs for 10 seconds, the display is then removed from view and participant are instructed to draw the designs from memory via pencil on paper. Each design is scored from 0 to 2 points representing accuracy and location. There are three learning trials. Test will be administered at index assessment, 12 weeks following cognitive rehab/ aerobic exercise, and at 6 months to examine cognitive retention
Time frame: Baseline, 12 weeks, & 6 month
Change from baseline anxiety & depression, at 12 weeks and 6 months
The following self report scale will be used to measure anxiety and depression: The Hospital Anxiety and Depression Scale (HADS) - The HADS is comprised of seven questions for anxiety and seven questions for depression, each reply has a likert scale ranging from 0-3. Total score will indicate: 0-7 = normal 8-10 = borderline abnormal 11-21 = abnormal

Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. The EQ5D-5 also records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled "The best health you can imagine" and "The worst health you can imagine".
