: Background Sleep disorders in multiple sclerosis (MS) patients are common. Dimethylfumarate is an oral disease modifying drug (DMT), whose impact on sleep is unknown. Objective The aim of this study was to characterize actigraphic patterns in MS patients treated with dimethylfumarate. Methods Twenty relapsing remitting MS patients with low to mild disability, aged 20-50y, treated with dimethylfumarate for more than 6 months were enrolled. All subjects had no history of sleep disorders. Actigraphy was used to study sleep patterns during a seven-day period. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Twenty healthy subjects served as controls. Results Our results showed statistically significant differences between some actigraphic patterns in MS patients treated with dimethylfumarate and healthy subjects, but the values for patients were still within normal limits. PSQI score was higher in MS patients compared to controls. Conclusions Our findings suggest that dimethylfumarate, an oral DMT with a favourable benefit-risk profile, does not strongly alter sleep patterns in MS patients with low to mild disability and with no history of sleep disorders. Actigraphy is a simple diagnostic tool, able to support an objective measure of sleep parameters. The simplicity of application may allow considering its use for a screening of sleep disorders in MS patients.

Abstract

: Background Sleep disorders in multiple sclerosis (MS) patients are common. Dimethylfumarate is an oral disease modifying drug (DMT), whose impact on sleep is unknown. Objective The aim of this study was to characterize actigraphic patterns in MS patients treated with dimethylfumarate. Methods Twenty relapsing remitting MS patients with low to mild disability, aged 20-50y, treated with dimethylfumarate for more than 6 months were enrolled. All subjects had no history of sleep disorders. Actigraphy was used to study sleep patterns during a seven-day period. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Twenty healthy subjects served as controls. Results Our results showed statistically significant differences between some actigraphic patterns in MS patients treated with dimethylfumarate and healthy subjects, but the values for patients were still within normal limits. PSQI score was higher in MS patients compared to controls. Conclusions Our findings suggest that dimethylfumarate, an oral DMT with a favourable benefit-risk profile, does not strongly alter sleep patterns in MS patients with low to mild disability and with no history of sleep disorders. Actigraphy is a simple diagnostic tool, able to support an objective measure of sleep parameters. The simplicity of application may allow considering its use for a screening of sleep disorders in MS patients.
