Restless Legs: What It Is and What the Evidence Says

Restless legs syndrome is common, frequently misattributed to cramp or anxiety, and has a genuinely well-characterised link to iron status that is worth knowing about.

The defining features

Diagnosis rests on a specific symptom pattern: an urge to move the legs, usually with an uncomfortable sensation that is hard to describe; onset or worsening during rest or inactivity; partial or complete relief with movement; and worsening in the evening or at night. All four features are required, and that specificity is what distinguishes it from cramp, positional discomfort or general fidgeting. Sleep disruption is the main functional consequence.

The iron and dopamine link

Brain iron status, particularly in the substantia nigra, is implicated, and iron is a cofactor in dopamine synthesis. Low ferritin is associated with symptoms even where it sits within the conventional normal range, and treatment guidance often uses a higher threshold for restless legs than for anaemia generally. This makes serum ferritin one of the more useful tests to request. Secondary causes include pregnancy, kidney disease and certain medications including some antidepressants and antihistamines.

Management

Correcting low iron where present is a first-line consideration and can be genuinely effective. Reviewing medications that can provoke or worsen symptoms is worthwhile. Sleep regularity, moderate exercise, and reducing caffeine and alcohol in the evening help some people. Pharmacological options exist for more severe cases and should be discussed with a doctor, particularly given that long-term dopamine agonist use carries a risk of augmentation, where symptoms worsen over time on treatment.
