ABSTRACT

Restless legs syndrome is a sensory- motor disorder characterized by the presence of discomfort on the lower extremities. Appears at night, right before bed, and improves with movement. It has a high co-morbidity with periodic limb movements disorder, which causes involuntary and periodic, short and stereotyped limb movements while sleeping. Both disorders affect the quality of sleep of those who suffer from them. An alteration in the metabolism of iron, in addition to dopaminergic dysfunction has been described in these patients. Also cortical hyperexcitability had been described for this disorder. First choice treatment is the use of dopamine agonists; however, chronic use is associated with increase in symptoms. On the other hand, therapy with repetitive low frequency transcranial magnetic stimulation has been effective in some disorders characterized by cortical hyperexcitability. The objective of this work was to describe the effect of transcranial magnetic stimulation on the sleep pattern in a 33-year-old male patient with restless legs syndrome and periodic limb movements disorder. This patient was clinically evaluated in order to confirm the diagnosis, accompanied by a first Polysomnographic study. Ten daily consecutive sessions of low frequency transcranial magnetic stimulation (‹1 Hz, 1,000 pulses per day) were applied, registering improvement in objective data associated with restless legs syndrome and periodic limb movements by increase in total sleep time and decreased amount of movements and also by improvement in subjective data collected by the patient. Therefore the transcranial magnetic stimulation is considered an effective tool which should be studied in more detail.
