Willis-Ekboms sjukdom (WED)/Restless legs (RLS)

Senast uppdaterad: Senast reviderad:
Sakkunnig:


Definition:
Willis-Ekboms sjukdom (WED), också känt som Restless legs syndrom, RLS, karakteriseras av episoder av obehagskänsla i benen och oemotståndligt behov av att röra på benen.
Förekomst:
Prevalensen uppges i Sverige vara 11 % hos kvinnor och 6 % hos män. Förekomsten ökar med åldern. Kan också förekomma hos barn.
Anamnes:
Obehagskänsla i benen och oemotståndligt behov av att röra på benen som inträffar vid vila, vanligtvis på kvällen och natten, och som försvinner med rörelse.
Kliniska fynd:
Vid undersökning inga tecken på neurologisk sjukdom.
Diagnostik:
Klinisk diagnos. Blodprov med tanke på eventuell järnbrist bör tas.
Behandling:
Information och rådgivning. Järnbrist, och även järndepåer i nedre delen av normalområdet (s-ferritin ≤75 µg/L), behandlas med järntillskott. Eventuellt annan läkemedelsbehandling om dagliga (eller nästan dagliga) besvär av måttlig till svår grad som påverkar sömn och funktion dagtid.
