Multiple sclerosis (MS) is a chronic progressive autoimmune disease. Fatigue, depression and cognitive impairments are the most common symptoms of patients with MS. Whereas there is extant research on fatigue, depression, and cognitive impairment of patients with MS during the clinical course, no research focused on the long term changes of psychological functioning, sleep problems, and physical activity on these patients. The aims of the present study were therefore to examine changes in physical activity, sleep disturbances, and mental toughness over a 1.5-year period of time in people with multiple sclerosis after the onset their MS.

A total of 18 patients with diagnosed MS (mean age: M = 33.61 years) took part in this study. They completed a booklet of questionnaires covering socio-demographic data, mental toughness, sleep disturbances, and physical activity, at the onset of disease and 1.5 years later.

In total, 1.5 years after the onset of MS, patients had lower levels of vigorous physical activity, but not statistically significant change in moderate physical activity. Patients with sleep disturbances at the onset of disease had statistically significant sleep disturbances also 1.5 years later.

Compared to the onset of disease, 1.5 years later, patients with MS reported similar mental toughness traits, sleep disturbances and levels of moderate physical activity. The pattern of results of the present pilot study suggests that the onset of MS is not an obstacle for doing moderate physical activity. Based on the result of this study, sleep disturbances remains stable by time.
