Restless legs syndrome
The main characteristic of this disorder is the irresistible urge for patients to move the legs. Patients also reported unpleasant sensations of cramps and "pins", which can become very painful.
These disturbances are manifested during the resting, sitting or lying down and force the patient to rub hard to walk. The discomfort in the limbs mainly affect the legs, but not infrequently, the sensation also reaches the upper extremities (arms).
The discomfort usually begin during the vigil, at the end of the day or early night time. During the day the complaints refer or disappear completely. The RLS prevents an optimal sleep quality causing destructuring of the cycle, daytime sleepiness and depressive symptoms. These factors produce a reduction in the quality of life of patients. Epidemiological studies report a prevalence of 5-15% of the population and a very high percentage have family history of restless leg disorder.
