1 Study Design 121 Relapsing-remitting MS patients randomized to –Stress Management Therapy MS active treatment* 16 individual sessions conducted over 24 weeks Additional 24 weeks of follow-up –Wait-list control* MS treatment as usual for 10+ months 5-hour workshop after 10th month MRIs performed at weeks 8,16,24,32,40, & Relapsing-remitting MS patients randomized to –Stress Management Therapy MS active treatment* 16 individual sessions conducted over 24 weeks Additional 24 weeks of follow-up –Wait-list control* MS treatment as usual for 10+ months 5-hour workshop after 10th month MRIs performed at weeks 8,16,24,32,40, & 48 *All patients continued their usual disease-modifying therapy.

5 Clinical Outcomes No significant differences between groups in confirmed exacerbations –Baseline to week in Stress Management Therapy-MS (SMT-MS) group vs 22 in control group (P =.84) –Week 24−48 15 in SMT-MS group vs 18 in control group (P =.40) No significant differences between groups in Expanded Disability Status Scale over the trial period (P =.15) No significant differences between groups in confirmed exacerbations –Baseline to week in Stress Management Therapy-MS (SMT-MS) group vs 22 in control group (P =.84) –Week 24−48 15 in SMT-MS group vs 18 in control group (P =.40) No significant differences between groups in Expanded Disability Status Scale over the trial period (P =.15) Mohr DC, et al. Neurology. 2012;79:

6 Follow-Up at 48 Weeks No statistically significant differences remained between groups in terms of Cumulative number of Gd+ lesions Cumulative number of new or enlarging T2 lesions Patients remaining free of Gd+ lesions Patients remaining free of new T2 lesions Levels of stress No statistically significant differences remained between groups in terms of Cumulative number of Gd+ lesions Cumulative number of new or enlarging T2 lesions Patients remaining free of Gd+ lesions Patients remaining free of new T2 lesions Levels of stress Mohr DC, et al. Neurology. 2012;79:

7 Possible Reasons Why Benefits Were Not Maintained Patients were able to employ the new coping skills as long as they were receiving treatment, but were unable to continue these behavioral changes without ongoing program support Expectations on the part of patients and/or the supportive relationship provided by treatment may have accounted for the benefits of the SMT-MS intervention Patients were able to employ the new coping skills as long as they were receiving treatment, but were unable to continue these behavioral changes without ongoing program support Expectations on the part of patients and/or the supportive relationship provided by treatment may have accounted for the benefits of the SMT-MS intervention Mohr DC, et al. Neurology. 2012;79:

8 Conclusions Stress management therapy: Effective in reducing new Gd+ lesions and new/enlarging T2 lesions, even in patients with higher disease activity Findings provide firm evidence of the link between stress and increased MRI activity Ongoing stress management therapy may be necessary to sustain the benefit of treatment Stress management therapy: Effective in reducing new Gd+ lesions and new/enlarging T2 lesions, even in patients with higher disease activity Findings provide firm evidence of the link between stress and increased MRI activity Ongoing stress management therapy may be necessary to sustain the benefit of treatment
