This research looked at the capacity to work, either full or part time, in a group of people with MS in Sweden. It found that fatigue and heat sensitivity played a major part in limiting the ability to work. Those with a higher level of education were more likely to stay in employment possibly because they were more likely to have a desk-based, rather than a physical, job. Being able to work was strongly linked to a better quality of life.
Work plays a very important part in many people's lives. For people with MS, some symptoms may affect the ability to work more than others. Fatigue is a very common symptom in MS which affects many aspects of everyday life.
This study looked at the capacity to work and the health related quality of life of people with MS and assessed the influence of fatigue, sensitivity to heat, cognitive symptoms, level of disability and anxiety or emotional distress.
How this study was carried out
257 people with a definite diagnosis of MS living in eastern Sweden completed a questionnaire. Three quarters (76%) were women and all were of working age (between 20 and 65) although the average age was 48. All the participants had an EDSS (Expanded Disability Status Score) of 6.5 or less meaning that the maximum level of disability was needing two walking aids (such as walking sticks) to walk 20m without resting.
Information was collected from each person on their age, disease course, level of education and family circumstances. In addition, whether they worked full time or part time or were not working and whether they were on full or part time sick leave or received a disability pension. People were also asked whether heat made their symptoms worse.
Other symptoms and aspects of their lives were assessed using a series of questionnaires:
- Health related quality of life using the SF-36 Health Survey
- The level of fatigue using the Fatigue Severity Scale (FSS)
- Problems with memory, attention and concentration using the Perceived Deficit Questionnaire (PDQ)
- Anxiety and emotional distress using the Hospital Anxiety Depression (HAD) scale
What was found
Six out of ten (60%) participants reported working full or part time and they were more likely to be younger (average age of 45), have a lower level of disability and to experience less fatigue, heat sensitivity, cognitive symptoms and anxiety/emotional distress.
Three quarters (75%) of participants with a university education were working compared with just over half (52%) of those with a secondary school education. The latter group reported significantly more cognitive difficulties than those with a university education.
Fatigue had a major impact on daily life and people with heat sensitivity rated their health as significantly worse than those who were not heat sensitive. All aspects of health related quality of life were rated significantly higher by those working full or part time compared with those who were not working.
What does it mean?
In this study, those able to work reported significantly less fatigue than those not working. In addition, people who did not experience heat sensitivity had a greater capacity to work. Previous studies have shown that heat sensitivity increases fatigue so the two effects may be linked together. The researchers suggest that fatigue is a key symptom in MS as it has a major influence on both ability to work and quality of life.
The authors suggest that those with a higher level of education may be able to stay in work longer because they are more likely to do paperwork. In contrast, anyone who has a more physically demanding job will be more affected by increasing disability and so may be unable to stay in work. They suggest that it is important that people diagnosed with MS at a young age are encouraged to continue their education to a higher level so that they are more likely to be able to work for longer.
As heat sensitivity interferes with the ability to work, they suggest that workplace measures to cool the environment, such as air conditioning, or to cool the individual, such as cooling garments, should be considered.

More about fatigue and heat sensitivity
Fatigue is a common symptom in MS but there are ways to manage it including planning carefully, deciding on priorities and putting aside the least important tasks, asking others to lend a hand and pacing yourself carefully. You can read more about fatigue in the A to Z of MS or order our book Living with fatigue.
Heat sensitivity is also common and can make many symptoms worse including fatigue. There are also several suggestions of ways to stay cool in the A to Z – everything from cool drinks to cooling scarves to air conditioning.
