title: Sleep disorders in multiple sclerosis. Review.
abstract: Sleep disorders are common in patients with multiple sclerosis (MS) and play a crucial role in health and quality of life; however, they are often overlooked. The most important sleep disorders in this context are as follows: insomnia, restless legs syndrome, periodic limb movement disorders, and sleep-related breathing disorders (SRBD). It is unclear if MS-related processes (lesions, brain atrophy) can cause symptomatic forms of sleep apnea. MS-related narcolepsy-like symptoms are described in the literature and, in some cases, have resolved with methylprednisolone pulse therapy. Similarly, REM sleep behavior disorder (RBD) is very rare in MS, but it can be an initial sign of MS where cortisone therapy may be helpful and can be taken into account in this specific context. Independent diagnosis and treatment is required for all of the abovementioned conditions. Treating physicians and neurologists should be aware of these comorbidities and initiate specific therapy. Highly fatigued or sleepy MS patients should have polysomnography in order not to overlook these diagnoses.
