Restless leg syndrome and periodic limb movement disorder are common and broad conditions that are not exclusively associated with sleep. Their symptoms are at their worst when in bed and trying to sleep and can be disruptive to sleep if left untreated.
What is restless leg syndrome?
Restless leg syndrome is a disorder that causes unpleasant or tingling sensations in the legs. This can result in the urge to move or shake your legs frequently. It tends to occur in the evenings and at night and is usually relieved by movement.
What is periodic limb movement disorder?
Periodic limb movement disorder is characterised by repetitive movement of arms, legs, or both during sleep. Often, people are unaware of these movements, as they tend to occur primarily during sleep.
What are the symptoms of these conditions?
Symptoms of these two conditions generally occur in the evening or at night and can include;
- Unpleasant sensations in the legs, such as;
- Burning
- Tingling
- Aching
- Itching
- Pins and needles
- An urge to move your legs in response to these sensations
- The feeling of your legs being unable to stay still or be comfortable
- Uncontrolled jerking motions at night
- Similar sensations in your arms
These symptoms usually occur when you’re resting, lying or sitting down for a long time. They worsen in the evening and at night, especially when trying to fall asleep.
What are the causes of restless leg syndrome & periodic limb movement disorder?
The exact causes of these conditions are not entirely known; however, they have been associated with the following;
- Iron deficiency – due to inadequate iron intake or alternatively, blood loss. This is a common cause of restless legs.
- Having too much caffeine
- Alcohol
- Prescription medications – particularly antidepressants like venlafaxine and desvenlafaxine.
- Smoking
- Pregnancy
- Nerve damage in the legs
- Health conditions, such as;
- Chronic kidney disease
- Iron deficiency
- Anaemia
- Diabetes
- Arthritis
- Parkinson’s disease
What treatments for sleep disorders such as restless leg syndrome and periodic limb movement disorder can Manse Medical provide?
The initial step is to assess the possibility of iron deficiency so it can be treated. Treatment of iron deficiency is usually very helpful. It is also essential to see if medications that cause restless legs, such as antidepressants, can be stopped. Once iron deficiency has been addressed, various medications can be used to treat restless leg syndrome. The choice of appropriate medication for you will be guided very much by the rest of your medical history, as these medications do have the potential for side effects and drug interactions.
There is a connection between obstructive sleep apnoea and some cases of periodic limb movement disorder. As a result, it is possible that treating obstructive sleep apnoea can overlap and also be used to help treat restless leg syndrome.
An overnight sleep study measures limb movements and can help a specialist diagnose a periodic limb movement disorder. It can also show if the limb movements are a secondary response to another sleep disorder, such as obstructive sleep apnoea.
What lifestyle adjustments can I make to ease symptoms of restless leg syndrome and periodic limb movement disorder?
If you are experiencing the symptoms of these conditions, there are steps that you can take to alleviate them. These are relatively simple and can be done in the convenience and comfort of your own home.
Here are some things that you can try to ease your symptoms;
- Hot baths, heat packs, ice packs and leg massages
- Reducing caffeine and alcohol intake
