1. Criteria

There is an urge to move the legs, usually accompanied by or in response to uncomfortable and unpleasant sensations in the legs.
The urge to move or unpleasant sensations begin or worsen during periods of rest or inactivity.
The urge to move or unpleasant sensations are partially or totally relieved by movement.
The urge to move or unpleasant sensations are worse in the evening or at night than during the day or occur only in the evening or at night.

The symptoms in Criterion A occur at least 3 times per week and have persisted for at least 3 months.

The symptoms are accompanied by significant distress or impairment.

The symptoms are not attributable solely to another mental disorder, behavioral condition, substance effect, or medical condition.

2. Context

Restless legs syndrome is the uncomfortable urge to move the legs that tends to get worse at rest, worse in the evening, and at least partly better with movement. Patients often describe it as a sleep problem, but the key experience is the sensory-motor discomfort that makes resting and falling asleep hard.
Timing matters: Symptoms classically worsen in the evening or at night, which helps separate RLS from many other causes of leg discomfort.
Movement helps: Temporary relief with walking, stretching, or movement is a strong clue.
Medical review: Iron deficiency, pregnancy, renal disease, neuropathy, and medication effects all deserve attention in the workup.
Clinical focus: Standard measure for symptom severity and treatment response.

3. Validated scales

International Restless Legs Syndrome Rating Scale

Standard measure for symptom severity and treatment response.

Sleep diary

Helpful when symptoms are mainly discussed as difficulty settling or staying asleep.

Ferritin and iron studies

Not a psychiatric scale, but often clinically essential in the workup.

4. FDA approved treatments

FDA-approved medications for restless legs syndrome

Several medications have FDA labeling for moderate to severe primary restless legs syndrome, with selection shaped by augmentation risk, sedation, and comorbidity.

Common off-label medications

Interventional psychiatry modalities

Interventional psychiatry modalities are not standard treatments for restless legs syndrome.
Management usually depends on iron status, medication review, and sleep medicine or neurology-informed treatment.
ECT, TMS, and ketamine are not standard RLS interventions.
