Objective: Restless Legs Syndrome (RLS) is a common neurological disorder that affects patients’ sleep, emotional state and daily life negatively. In this study it was aimed to determine the sleep quality, daytime sleepiness and depression frequency in patients with RLS and their relation with duration and severity of illness.
Materials and Methods: In our center, 41 patients with primary RLS diagnosis were included in the study. Patients were divided into groups as mild, moderate, severe and very severe, according to the RLS severity scale of the International Restless Legs Syndrome Study Group. Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and Beck Depression Inventory were filled in by all the patients, including identity and sociodemographic data with illness information. Statistical analysis was performed among groups divided according to disease severity. Depressive symptoms of the disease duration and its relation with sleep problems were investigated.
Results: In this study 41 patients, 30 (73.2%) female, 11 (26.8%) male, were included. Of the patients participating in the study, 2 patients (4.9%) had mild RLS while 7 (17.1%) were very severely ill. Fourteen patients (34.1%) had moderate disease and 18 (43.9%) had severe disease. Bad sleep quality was found in 68.3% (n=28) of patients with RLS, excessive daytime sleepiness in 14.6% (n=6) severe depression in 7.3% (n=3) and totally 29.3% of patients (n=12) depressive symptoms were observed. As the severity of illness increased, sleep quality deteriorated and depressive symptoms increased (p<0.01).
Conclusion: Most of the RLS patients had poor sleep quality, a significant amount of daytime excessive sleepiness, and about one third of them had depression. As the duration and severity of the disease increases, the intensity of depressive symptoms increases. Remembering that RLS may have serious consequences and effective treatment of depression when accompanied should be planned without losing time.
