Restless legs syndrome (RLS), a neurological disorder, frequently co-occurs with psychiatric conditions. Patients with RLS and psychiatric issues exhibit fewer leg movements during sleep, highlighting the need for integrated care.
Area of Science:
- Neurology
- Sleep Medicine
- Psychiatry
Background:
- Restless legs syndrome (RLS) is a common neurological sleep disorder.
- A significant percentage of RLS patients (39%) also experience psychiatric comorbidities.
Purpose of the Study:
- To investigate the relationship between psychiatric comorbidities and RLS.
- To analyze the impact of psychiatric disorders on the presentation of RLS symptoms, specifically periodic leg movements in sleep (PLMS).
Main Methods:
- The study analyzed RLS patients with and without psychiatric comorbidities.
- Data on periodic leg movements in sleep (PLMS) were collected and compared between groups.
Main Results:
- Patients diagnosed with RLS and coexisting psychiatric comorbidities demonstrated a reduction in periodic leg movements during sleep.
- The presence of any psychiatric comorbidity was associated with fewer PLMS.
Conclusions:
- Psychiatric comorbidities are prevalent in Restless Legs Syndrome patients.
- The findings suggest that psychiatric disorders influence the polysomnographic features of RLS, specifically reducing PLMS.
- Clinicians should consider and assess for psychiatric disorders in individuals diagnosed with RLS for comprehensive patient management.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
