How Is Plmd Diagnosed

My kicking! PLMD Periodic Limb Movement Disorder-kicking during sleep

People may live with PLMD undiagnosed for some time. They may not even notice an impact on their sleep quality. Its actually more common for their sleep partner to experience disrupted sleep due to the movements. People typically seek treatment after their sleep partner notices the symptoms or once the other symptoms such as daytime sleepiness or fatigue begin to interfere with their daily functioning and wellbeing.

If you think you or your sleep partner may have PLMD, talk to your doctor. At your appointment, they will ask questions to better understand your sleep issues and determine if they may be caused by an underlying issue like an iron deficiency or diabetes. They may review your personal and family medical history, any medications you take, and your current sleep and lifestyle habits. Your doctor may collect a urine or blood sample, or order additional tests, to rule out another condition.

If your sleep partner describes your leg movements and your doctor suspects PLMD or a sleep disorder, they may refer you to a sleep specialist. A sleep specialist may order an overnight sleep study, known as a polysomnogram. While you sleep, your breathing will be monitored , as will your leg movements and other vitals. If the leg movements occur at least 15 times per hour you may receive a diagnosis of PLMD.

Diagnosis Of Plmd And Rls

  • For restless legs syndrome, a doctor’s evaluation

  • For periodic limb movement disorder, polysomnography

  • For either disorder, tests to check for a cause

Doctors can often diagnose restless legs syndrome based on symptoms reported by the person or the personâs bed partner. Doctors may suspect periodic limb movement disorder based on symptoms, such as insomnia, excessive daytime sleepiness, and/or excessive twitching just before going to sleep or during sleep.

These tests are done overnight in a sleep laboratory and are not done at home. In polysomnography, brain activity, heart rate, breathing, muscle activity, and eye movements are monitored while people sleep. People may also be videotaped during an entire night’s sleep to document limb movements. These tests may also be done after restless legs syndrome is diagnosed to determine whether people also have periodic limb movement disorder.

What Are The Symptoms Of Rls

According to the National Institute of Neurological Disorders and Stroke, people with RLS feel uncomfortable sensations in their legs, especially when sitting or lying down, accompanied by an irresistible urge to move the affected limb. These sensations less commonly affect the arms, trunk, or head. Although the sensations can occur on just one side of the body, they most often affect both sides.

Because moving the legs relieves the discomfort, people with RLS often keep their legs in motion to minimize or prevent the sensations. They may pace the floor, constantly move their legs while sitting, and toss and turn in bed.

A classic feature of RLS is that the symptoms are worse at night with a distinct symptom-free period in the early morning, allowing for more refreshing sleep at that time. Other triggering situations are periods of inactivity such as long car trips, sitting in a movie theater, long-distance flights, immobilization in a cast, or relaxation exercises. Many individuals also note a worsening of symptoms if their sleep is further reduced by events or activity.

RLS symptoms may vary from day to day and in severity and frequency from person to person.

People who have both RLS and an associated medical condition tend to develop more severe symptoms rapidly. In contrast, those who have RLS that is not related to any other condition and experience onset at an early age show a very slow progression of the disorder many years may pass before symptoms occur regularly.

Environmental And Dietary Factors

The following environmental and dietary factors can trigger or worsen RLS:

  • Iron deficiency. People who are deficient in iron are at risk for RLS, even if they do not have anemia.
  • Folic acid or magnesium deficiencies.
  • Smoking.
  • Caffeine. Coffee drinking is specifically associated with PLMD.
  • Stress.

Drugs that may worsen or provoke RLS include:

  • Antidepressants
  • Calcium channel blockers
  • Metoclopramide
  • Antihistamines
  • Spinal anesthesia

The limb movements, while usually in the lower extremities, can also occur in the upper extremities in certain cases. The movements can be described as a muscle twitching or jerking. The limb movements happen between 15 to 60 seconds of each other and can vary from night to night. Most of the time the person experiencing the limb movements does not know they are happening and are reported by a spouse or loved one.

Treatment For Periodic Limb Movement Disorder

In many cases where excessive daytime sleepiness and chronic insomnia are not present, treatment is not often necessary for PLMD. Unless the patient or the bed partner are experiencing negative symptoms of sleep loss or other medical issues due to the nocturnal movements, treatment may not be necessary.

The most common form of treatment for PLMD is prescribing the same medications as those for Parkinson’s disease, anticonvulsant medications, benzodiazepines, dopaminergic drugs, and narcotics.

There is no cure for periodic limb movement disorder and treatment for the disorder must be continued to reduce symptoms.

Patients with PLMD should also avoid certain substances that can exacerbate symptoms such as caffeine, alcohol, or antidepressants.

If your nocturnal leg movements are causing you or your bed partner to lose sleep, you may want to consult with your physician or a sleep specialist for diagnosis.

What Are The Symptoms Of Periodic Limb Movement Disorder

PLMD movements typically occur every 20 to 40 seconds in batches of 30 minutes or more during the night. They are more common in the legs but may occur in the arms as well. The limb movements typically occur during non-rapid eye movement sleep.

The most common symptoms of PLMD include the following:

  • repetitive leg movements in one or both legs and sometimes in the arms, which may involve flexing of the big toe, upward bending of the knee or ankle, or twitching of the hip
  • restless, unrefreshing sleep
  • multiple awakenings at night
  • daytime sleepiness and drowsiness
  • irritability, behavior problems, and decline in performance at school or work due to lack of quality sleep

People with PLMD may also have symptoms of RLS. This may include burning or tingling sensations in the legs when they lie down. Not everyone with PLMD has RLS, but according to the American Sleep Association, about 80 percent of people with RLS also have PLMD.

Diagnosing Restless Legs Syndrome

There’s no single test for diagnosing restless legs syndrome.

A diagnosis will be based on your symptoms, your medical and family history, a physical examination, and your test results.

Your GP should be able to diagnose restless legs syndrome, but they may refer you to a neurologist if there’s any uncertainty.

There are four main criteria your GP or specialist will look for to confirm a diagnosis. These are:

  • an overwhelming urge to move your legs, usually with an uncomfortable sensation such as itching or tingling
  • your symptoms occur or get worse when you’re resting or inactive
  • your symptoms are relieved by moving your legs or rubbing them
  • your symptoms are worse during the evening or at night

Prevalence Of Periodic Limb Movement Disorder

Restless Leg Syndrome and Periodic Limb Movement Disorder

PLMD is believed to prevalent in roughly 4-11% of adults, although it is more common in elderly women. PLMD is frequently a symptom of restless leg syndrome . Approximately 80% of patients with RLS have PLMD. However, while having RLS is a strong indication that a patient will also have PLMD, having PLMD is not a strong indicator of having RLS.

Periodic Limb Movement Disorder: Dancing In The Dark

My husband has Periodic Limb Movement Disorder. Its disturbing our sleep, and all the doctors want to do is give him dopamine. What else could he do?

Andrew Weil, M.D. | July 3, 2009

Periodic limb movement disorder causes repetitive limb movements that disrupt sleep. The movements usually involve the legs, particularly the big toe, ankle, and knee, but can also include movements of the hip and sometimes the arms. This often occurs during light sleep and at regular intervals of five to 90 seconds, but the frequency can vary from night to night. Most people with symptoms of PLMD arent aware that their limbs are moving, but bed partners are. Affected individuals are often tired or sleepy during the day as a result of frequent waking during the night and poor quality of sleep.

Diagnosis is made on the basis of overnight monitoring with a device that records body movements during sleep. Respiration is also monitored to make sure the cause of disrupted sleep is not a breathing problem .

PMLD hasnt been widely studied, and we dont know how prevalent it is. It occurs among both men and women and seems more common with advancing age. PLMD has also been linked to uremia, diabetes, iron deficiency, and spinal cord injury.

Dr. Naiman said that iron and vitamin C supplements can help many individuals with PLMD and suggested consulting a qualified physician or nutritionist for a personalized treatment plan .

Andrew Weil, M.D.

How Is Plmd Different From Rls

Patients with periodic limb movement disorder often aren’t even aware of the disorder as the leg movements occur involuntarily during their sleep. Patients with restless leg syndrome move their legs voluntarily to relieve feelings of discomfort that are often described as pulling, throbbing, itching, creeping, or other uncomfortable sensations. These symptoms manifest themselves during periods of rest such as when going to bed and the only temporary relief from the discomfort is to move the legs.

How To Treat Periodic Limb Movements

When it is necessary to treat periodic limb movement disorder, the same drugs that are used for restless legs syndrome also work. These include drugs that replace a chemical in the brain called dopamine. These drugs are also used to treat Parkinsons disease. However, if you have periodic limb movement disorder, you are not at an increased risk of getting Parkinsons disease. Other medications used include the following:

  • Sleeping tablets
  • Some anti-seizure medications
  • Narcotic pain killers

Low iron levels have been associated with periodic limb movements during sleep. Your doctor may recommend a blood test to check your iron levels and if low, an iron supplement may be recommended.

What Causes Restless Legs Syndrome

In the majority of cases, there’s no obvious cause of restless legs syndrome. This known as idiopathic or primary restless legs syndrome, and it can run in families.

Some neurologists believe the symptoms of restless legs syndrome may have something to do with how the body handles a chemical called dopamine. Dopamine is involved in controlling muscle movement and may be responsible for the involuntary leg movements associated with restless legs syndrome.

In some cases, restless legs syndrome is caused by an underlying health condition, such as iron deficiency anaemia or kidney failure. This is known as secondary restless legs syndrome.

There’s also a link between restless legs syndrome and pregnancy. About 1 in 5 pregnant women will experience symptoms in the last three months of their pregnancy, although it’s not clear exactly why this is. In such cases, restless legs syndrome usually disappears after the woman has given birth.

Periodic Leg Movements Research & Treatments

PLMS a sleep disorder characterized by involuntary movements of the legs while asleep. People who suffer from PLMS can be unaware of their limb movements, as they do not always wake from them.

These movements happen during the night, at regular intervals before one enters REM sleep. Sufferers often complain of the inability to fall asleep or to remain asleep in association with PLMS. Men and women are equally affected by PLMS children may develop it as well. This disorder is most common in people over the age of 65, although one may develop it at any age.

Is Periodic Limb Movement Disorder Related To Restless Leg Syndrome

Restless Leg Syndrome and Periodic Limb Movement Disorder by Dr. Ruchir P. Patel

Sufferers of PLMS may also experience some of the same symptoms of RLS like burning, tingling sensations or general discomfort in their legs when they lay down to rest. Not everyone who has PLMS has RLS however, about 80% of people who suffer from RLS also suffer from PLMS.

Often ones bed partner will be more aware of the movements than the sufferer is. Many times when one suffers from PLMS, they may not fully awaken from the movements, although it does disrupt their sleep. Additionally, one may find they frequently wake up just as they are falling asleep and not know what work them, as the leg movements usually last only a few seconds.

These movements will often occur in the first stage of your sleep cycle, before REM sleep. REM sleep is the dream cycle of sleep it is also the episode in which one obtains their most restful sleep. Constant disruptions of the sleep cycle can keep one from attaining REM sleep, leaving a person unrested in the morning. During the REM sleep cycle a persons voluntary muscles are paralyzed, which keeps one from acting out their dreams. It is possible that because of this paralysis, PLMS can only occur before or after REM sleep.There is cross over between individuals with PLMS and Restless Legs Syndrome .
