ANECDOTE

1950s Discovery Linked RLS To Iron Treatment

  • In 1953 Dr. Nils Lördalén observed many RLS patients had anemic iron deficiency and improved after iron treatment.
  • Some patients’ symptoms disappeared entirely while iron levels stayed normal.
INSIGHT

Blood Iron Tests Miss Most RLS Cases

  • Only about 15% of RLS patients show peripheral (blood) iron deficiency despite historical assumptions.
  • This discrepancy prompted investigation into brain-specific iron deficits.
ADVICE

See A Sleep Specialist For Diagnosis

  • If you suspect RLS, get evaluated by a sleep specialist who will review history and symptoms for diagnosis.
  • Expect blood tests for iron and ferritin as part of the workup.
