Frequently asked
Plain-language answers about restless legs, this screener, and what evaluation costs at a Class A hospital in China.
- What's the IRLS severity grading?
- 0 none; 1–10 mild; 11–20 moderate; 21–30 severe; 31–40 very severe. Scores of 15 or above conventionally support pharmacological management alongside lifestyle measures.
- What's the workup for RLS?
- Evaluation includes serum ferritin (target ≥ 75–100 ng/mL — iron deficiency is a major modifiable contributor), TSH, B12, magnesium, and renal function. Polysomnography is rarely needed for typical RLS but may be indicated to rule out concurrent OSA. Cost USD 80–160 at a Class A sleep medicine centre.
- Treatment options?
- First-line: iron supplementation if ferritin low; address contributors (caffeine, alcohol, antihistamines, antidepressants where possible). Pharmacotherapy: gabapentin enacarbil / pregabalin, dopamine agonists (with augmentation risk awareness), low-dose opioids in refractory cases. All available at Class A sleep / neurology departments.
