Sleep Disorders and Quality of Life in Patients With Multiple Sclerosis

Multiple sclerosis(MS) is a neurodegenerative disease of the central nervous system that commonly affects young adults. The disease is characterized by neurological symptoms that may lead to long-term physical disability. Patients with MS have many other problems associated with their disease, as obstructive sleep apnea (OSA) that characterized by obstructions of the respiratory tract throughout the night leadind to wake up the patients many times to achieve the right muscle tone and receive adequate oxygenation. Most patients with MS complain from poor sleep.It may be due to pain, fatigue, depression and immunotherapy that have been considered as potential factors, which could have role in sleep disturbances among MS patients.Restless leg syndrome (RLS) may trigger sleep disorders, especially insomnia, in patients with MS. Patients with sleep disorders may complain excessive daytime sleepiness, impaired concentration, altered mood, and fatigue. they are at risk to develop other problems,as vascular diseases, obesity, and diabetes, which further threaten long-term health.So patients with MS have lower quality of life(QoL) than healthy ones. Multiple Sclerosis Quality of Life-54 (MSQoL-54) questionnaire is the most common and standardized disease-specific questionnaire that based on the generic SF-36 QoL instrument.
