Restless Legs Syndrome: A Care Staff Guide to Recognition and Support

Restless legs syndrome (RLS) is easy to miss and easy to misunderstand. A resident who cannot settle at night, keeps walking the corridor, or says their legs feel strange may be labelled agitated or anxious when the cause is a treatable neurological condition. NHS Lothian's neurology advice for GPs gives a clear picture of how it is recognised and managed, and it shows where care staff can help.

What is restless legs syndrome?

According to the advice, RLS is diagnosed clinically, after other explanations are excluded. The typical features are an urge to move the legs, often with uncomfortable or unpleasant sensations. Symptoms begin or worsen at rest or inactivity and are relieved by movement such as walking or stretching. They are worse in the evening and at night, which disturbs sleep. RLS is often associated with periodic limb movements during sleep, and a family history is common.

A useful screening question is whether unpleasant restless feelings occur in the legs when trying to relax or sleep, and whether they are relieved by walking or moving. Staff can use this to describe what they have seen to the nurse or GP.

Conditions that can look similar

The advice lists mimics including peripheral neuropathy, cramps, varicose veins, akathisia, anxiety and spinal stenosis. Hypnic jerks, the sudden jolts people feel when falling asleep, are commonly misdiagnosed as RLS but are not the same condition. This is why a proper assessment matters.

Looking for causes

• Iron deficiency. The advice says all suspected RLS should have a basic blood screen including glucose and serum ferritin, and that oral iron should be replaced if ferritin is low or low-normal.
• Medicines. Tricyclic antidepressants such as amitriptyline may worsen symptoms, so medicines should be reviewed. Our guide to polypharmacy and deprescribing explains why regular reviews matter.
• Other sleep disorders. Any co-existing sleep disorder should be identified and managed.

Non-drug measures

The advice states that most people can be managed without medication. Suggestions include good sleep hygiene, including avoiding evening stimulants, cognitive behavioural therapy for insomnia, relaxation, walking or stretching before bed, a warm evening bath and massage. Care staff can help by building a calming evening routine, supporting short walks and avoiding caffeine late in the day.

Medicines and their risks

Medicines are reserved for symptoms with a major impact on quality of life, and the advice recommends using the lowest possible doses to reduce augmentation. Augmentation means that symptoms worsen, or start earlier in the day, after a period of successful treatment, and the advice associates it with dopamine agonists. Gabapentinoids, which are not licensed for RLS, are first line in many guidelines. Dopamine agonists such as ropinirole, pramipexole and the rotigotine patch are licensed, and the advice says patients should be counselled about impulse control disorders such as excessive gambling, shopping and hypersexuality. Our guide to gambling-related harms explains why NICE lists dopamine agonists among medicines that can affect impulse control.

Staff should watch for sudden changes in behaviour after starting or changing these medicines, such as new spending, gambling or preoccupations, and report them promptly. Never advise stopping a prescribed medicine suddenly.

How care staff can help

• Notice and describe. Record when symptoms occur, what the person does to relieve them, and how they affect sleep and mood.
• Do not label. Avoid describing restlessness as attention-seeking or agitation without asking about leg sensations.
• Support sleep. Keep evenings calm, limit evening stimulants and make it safe to walk at night.
• Report changes. Tell the GP or nurse about worsening symptoms, new behaviours or sleep problems.

Why it matters for wellbeing

Poor sleep affects mood, concentration, appetite and the risk of falls the next day. A person who walks the corridor at night to ease their legs may be tired and unsteady by morning. Treating sleep disruption as a care need, not a behaviour problem, helps the team to respond with patience and to ask the right clinical questions. Talk with the person about how their legs feel, listen for their own words, and share them with the clinician.

Recording and review

A simple sleep and symptom diary helps the GP assess whether iron, medicines or other causes are involved and whether a treatment is helping. Review the care plan regularly and involve the person in choosing what works for them. The advice notes that treatment options are limited and that neurology review is available for diagnostic uncertainty or management problems.

Supporting staff learning

Sleep problems affect mood, falls and daytime function. Learnsignal's CPD courses can help teams plan learning on common but under-recognised conditions.

Frequently asked questions

Is RLS just anxiety? No, although anxiety can mimic it. The key features are an urge to move the legs that is worse at rest and in the evening and relieved by movement.

Can iron help? The advice recommends checking ferritin and replacing iron when it is low or low-normal.

Are there risks with treatment? Yes. Dopamine agonists are linked with augmentation and impulse control problems, so prescribers use the lowest possible doses and review regularly.
