How Can Life Stressors Affect Multiple Sclerosis Flares?

A couple of stressors including poverty, abuse, and divorce were found to be linked to worsening health and functional outcomes for Multiple sclerosis patients ().

Using survey data from more than 700 people with MS, researchers discovered //that stressful events occurring both in childhood and adulthood contributed significantly to participants’ level of disability.

The results are published in Brain and Behavior.

“MS is the leading cause of non-traumatic disability among young adults, and additional research is needed to identify these external drivers of disability that can be addressed or prevented, including stress, to improve functional outcomes,” said co-author Tiffany Braley, M.D., M.S., director of the Multiple Sclerosis/Neuroimmunology Division and Multidisciplinary MS Fatigue and Sleep Clinic at University of Michigan Health.

“This knowledge is needed to inform MS research as well as clinical care. Referrals to resources, such as mental health or substance use support could help reduce the impact of stress and enhance wellbeing,” Braley said.

Multiple sclerosis is treated with drugs that modify the course of the disease, suppress immunity and relieve symptoms.

Incidence of Multiple Sclerosis

More than 2.8 million people in the world have MS (), an autoimmune condition that affects the brain and spinal cord, in which the protective layer of nerve cells is attacked by the body’s immune system. People with MS can experience unique, often painful, exacerbation of their symptoms known as a relapses, exacerbations or “flares”.

Initially in the study, both childhood and adult stressors were significantly associated with worse burden caused by relapse after the onset of the COVID-19 pandemic. However, the association between childhood stressors and disease burden lost significance when further accounting for experiences in adulthood.

Studies focused on stress and MS that don’t account for the full lifespan, researchers say, could miss vital information or overestimate the relationship between childhood stressors and health outcomes.

“It is important to use a lifespan approach in future work to better understand patterns and inform symptom management. For example, we are expanding upon this work to investigate mechanistic pathways through sleep, smoking and mental health, through which stressors may lead to worse MS outcomes including increased disability, pain and fatigue.”

Diet and Nutrition for Stress Management
Eating plans may go haywire during stress, but with a little effort you can put up a well balanced nutritious meal that can help with stress management.

This work was supported in part by the National Institutes of Health and the National Institute of Nursing Research.
