Restless Leg Syndrome in Parkinsonism with Dr. Abdul Rana MD

Having RLS in 2002 and/or 2008 was associated with a higher risk of constipation in 2012, compared with controls. Only individuals who had RLS in both 2002 and 2008 showed higher odds of having possible RBD alone, and both constipation and possible RBD in 2012, indicating a potential association between continuous/recurrent RLS and , according to the researchers.

They cautioned that constipation is a relatively non-specific Parkinsons symptom and may not indicate a direct link between RLS and Parkinsons.

No differences were found between olfactory scores of men with or without RLS. However, the team noted that olfactory scores were only available from a subset of participants. Additionally, the timing of the smell sense analysis may also have influenced this result, since a loss of sense of smell has been reported as a relatively late symptom in the early stages of Parkinsons compared with RBD and constipation, they said.

We assessed the association between RLS and prodromal signs, but not between RLS and incidence. However, our focus was on identifying whether RLS is an early indicator of the underlying common disease process in , the authors wrote.

The findings warrant future studies for RLS and Parkinsons incidence in the long-term, they said.

Among the studys limitations, the authors mentioned that the link between Parkinsons and RLS may differ by gender, since women, although they have a reduced risk for Parkinsons, are more susceptible to RLS.

Can Restless Legs Syndrome Develop Into Something More Serious

Most people with restless legs syndrome have the “idiopathic” form, meaning there’s no known cause. For them, there is no risk of RLS developing into something more serious, like Parkinson’s disease.

Restless legs syndrome can get worse in people with other medical conditions if they don’t get those conditions treated.

Parkinsons & Restless Leg Syndrome: Using Dopaminergic Medication

Because RLS is well-treated by medications that also treat PD, it is likely that some aspect of brain dopamine function is altered in RLS. However, unlike in PD, in which the deficit in substantia nigra dopamine-producing cells can be proven in many ways, no such abnormality has been shown in RLS. For example, studies show that DaTscan results are not abnormal in RLS.

Using dopaminergic medications to treat RLS however can be tricky. In some people they can lead to a phenomenon known as augmentation, in which long term use of dopaminergic medications can worsen the symptoms making them appear earlier in the day or migrating to the upper body in addition to the legs.

Evidence Of Dopaminergic Dysfunction In Rls

Observation studies of RLS in diseases which involve dopaminergic systems lend support to the hypothesis that dopaminergic dysfunction is present in RLS. One family with comorbidity of Huntington’s disease and idiopathic RLS has been reported. All family members affected by RLS also had HD, but not vice versa . Ondo and colleagues found a very high rate of undiagnosed RLS in their patients presenting with essential tremor. However, unlike other “secondary” forms of RLS, this finding was also associated with a high familial history of RLS . A study of comorbidities in Tourette syndrome including RLS investigated 144 probands with TS or chronic tics and their parents. RLS was present in 10% of probands and 23% of parents with no gender differences .

Does Having Rls Increase The Risk Of Developing Pd

Restless Leg Syndrome And Parkinson Disease

Since RLS affects as much as 4-10% of the US adult population, it is clear that the vast majority of those with RLS do not ever develop PD.

Despite this, it still might be the case that RLS increases the risk of subsequently developing PD. There have been many studies trying to figure this out with conflicting results. Some studies show that there is no increased risk and others show that having RLS confers about a two-fold increased risk of developing PD over the general population.

Detections Of The Levels Of Neurotransmitters In Csf And Serum

The levels of neurotransmitters, including DA, 5-HT, Ach and NE in CSF and serum from PD patients, were measured by high-performance liquid chromatography. Phenomenex 150×2mm, 150×3mm chromatographic column, and liquid chromatography tandem mass spectrometry 6410 instrument were from Agilent , and standard samples were from Sigma .

Parkinson’s And Restless Legs Syndrome

It is difficult to confirm exactly how Parkinsons can affect RLS or vice versa. RLS is a condition in its own right, occurring in people both with and without Parkinsons although it is thought to be almost twice as likely to occur in people with Parkinsons.

RLS can also be difficult to diagnose in Parkinson’s as it may come and go and can be confused with other symptoms of the condition such as akathisia or internal tremor. RLS can also cause night-time pain which may be mistaken for articular issues in people with Parkinson’s.

Restless Legs Syndrome Triggers

Sitting or resting are common triggers for RLS symptoms. Additionally, some substances can make symptoms worse. These include:

  • Alcohol
  • Nicotine
  • Medications, including certain drugs used to treat nausea, colds and allergies, and mental health conditions

Incidentally, most of these substances when taken in excess or too close to bedtime can also adversely affect our sleep architecture.

Is Rls More Common In Pd

Pain in Legs in Parkinsonism with Dr. Abdul Rana Neurologist

But what about the other possibility? Do patients with PD have an increased risk of RLS over the general population? Is it the same RLS as the person without PD has, or is it different? These questions have been difficult to answer. Of course, since PD affects about 1.5% of the elderly, and RLS in about 4-10% of the population, there will be some coincidental overlap. In addition to this however, patients with PD can have sensations that feel like RLS when their dose of dopamine medication is wearing off. These sensations are not truly RLS since they do not have the key features of RLS described above and fluctuate with medication timing, but they can be easily confused with RLS by the person with PD.

Studies of people with PD that assess for RLS and compare to a control group are hindered by the fact that the majority of patients with significant PD are under treatment with medications that affect RLS. Over the years, there have been multiple studies investigating whether RLS is more common in PD than in the general population. Different studies come to different conclusions. Studies conducted in which a group of people with PD are directly compared to a group of people without PD typically show that RLS is more common in PD than the general population.

Detections Of The Levels Of Iron And Related Proteins In Csf And Serum

The levels of iron and related proteins, including ferritin, transferrin and lactoferrin in CSF and serum from PD patients were detected by Enzyme Linked Immunosorbent Assay. Ab83366 kit for iron, Ab108837 kit for ferritin and Ab108911 kit for transferrin were from Abcam Company . E01L0224 kit for lactoferrin was from Shanghai Lanji Biological Limited Company .

People With Parkinson’s Disease More Likely To Have Leg Restlessness Than Restless Leg Syndrome

Date:
American Academy of Neurology
Summary:
People with Parkinson’s disease may be more likely to have a movement disorder called leg motor restlessness, but not true restless legs syndrome as previous studies have suggested, according to a new study.

People with Parkinson’s disease may be more likely to have a movement disorder called leg motor restlessness, but not true restless legs syndrome as previous studies have suggested, according to a study published in the Nov. 9, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Restless legs syndrome is a sleep and movement disorder. People with the disorder have the urge to move their legs to stop uncomfortable sensations. The urge occurs when the person is at rest, in the evening, and is temporarily relieved by movement. In leg motor restlessness, people also have the urge to move their legs, but it is either not worse when they are at rest or during the evening or it does not go away when they move their legs.

Because restless legs syndrome and Parkinson’s disease both respond to the drug dopamine, researchers have looked for connections between the two disorders. Some studies have shown that people with Parkinson’s disease are more likely also to have restless legs syndrome than people who don’t have Parkinson’s disease. But those studies have looked at people with advanced cases of Parkinson’s who have taken dopamine drugs for many years.

What Treatment Is Available

Restless Leg Syndrome & Parkinson

RLS is a condition that is treatable and generally susceptible to pharmacologic therapy. A wide range of different treatment options is available, including drugs that modulate certain calcium-channels, dopaminergic agents, opioids, and benzodiazepines. However, the medical condition most commonly associated with RLS is iron deficiency so your doctor should first check your ferritin levels . If levels are low you will be given an iron supplement. For some people increasing the ferritin levels will eliminate or reduce the RLS symptoms.

Some Parkinson’s medications can make RLS worse and should be avoided. For example, some people who take levodopa complain that RLS symptoms occur during the day, as well as evenings, and may also involve the arms and the face. These symptoms typically worsen late in the night as the medication wears off. It is therefore often preferable to use dopamine agonists such as pramipexole or ropinirole tablets, or rotigotine skin patches instead of levodopa when treating Parkinsons and RLS.;

If you are already taking dopamine agonists to manage Parkinson’s symptoms and you still experience RLS symptoms, then your doctor may suggest you try other medications, such as gabapentin, pregabalin, opioids or clonazepam, although these may or may not be licenced to treat RLS in your country.

How Can I Get A Good Night’s Sleep Despite Restless Legs Syndrome

Experts agree that simply changing your behavior can often help you sleep if you have restless legs syndrome. For people with mild to moderate RLS, these steps can reduce or prevent symptoms:

  • Cut down on caffeine.
  • Stop smoking, or at least cut back.
  • Go to bed and get up at the same time each day, including weekends.
  • Exercise regularly, but moderately .
  • Apply heat or ice, or soak in a hot bath.

In Vivo Corneal Confocal Microscopy

All participants underwent IVCCM bilaterally, or unilaterally if one eye met exclusion criteria. The central corneal subbasal nerve plexus was imaged as previously described. Briefly, a topically anesthetized eye was examined with the Heidelberg Retinal Tomograph 3 laser-scanning confocal microscope with the Rostock Corneal Module . A single examiner performed all eye scanning, recording images of the subbasal nerve plexus across a wide area of the plexus using the built-in fixation light to access paracentral regions and continually adjusting the focus to the plexus depth. Mosaics were generated with an automated computer algorithm to select nerve plexus images from the recorded data using tissue classification and to stitch together adjacent images. Depth variations of subbasal nerve fiber paths were mapped onto a single two-dimensional mosaic image. A separate automated algorithm was used for detection and tracing of nerve paths and branching points, from which the mean values of CNFL and CNBD were calculated,. Averaged values between both eyes were used where applicable.

Sensory Suggested Immobilization Test

The PD+RLS group was further assessed with the sensory SIT,. Patients were observed in the evening, between 8PM and 9PM, lying down in a 45° recumbent position and instructed to move as little as possible with legs extended. Patients were asked every 10min to indicate their perceived severity of leg discomfort, using a visual analog scale of 0100, generating seven individual values for each participant. A mean leg discomfort score >11 was used as supportive of RLS diagnosis. This cutoff value has previously been evaluated and proposed as appropriate in the context of RLS diagnosis in PD.

The sensations associated with RLS are distinct from normal sensations experienced by those who dont have the disorder. This makes them difficult to characterize. According to the International Classification of Sleep Disorders, the words and phrases most commonly used by RLS patients to describe the feelings are:

  • Twitchy

As a result of the sleep disturbances associated with RLS, patients often experience fatigue and daytime sleepiness. Sleep deficiency is associated with depression, anxiety, heart disease, and obesity. RLS patients are at greater risk for these issues as well. Concerns about sleep are the main reason RLS patients seek medical care for their condition.

Is There A Link Between Restless Leg Syndrome And Parkinson’s Disease

Previous studies have suggested that there is a link between RLS and PD due to both conditions sharing the common feature of dysfunction in the part of the brain that produces dopamine. Another commonality between these two conditions is that they have been shown to run in the family. About half of the cases are in patients that have relatives with the disorder. Another argument for the medical linkage of these neurological disorders is that they share the same treatments – no other common disorder is treated with the same dopamine agents.

Even though earlier studies have shown a significant prevalence of RLS in patients with Parkinsons, researchers have not been able to find a common patient demographic or Parkinsons treatment to reliably predict the development of restless leg syndrome. Also through studies, they have found that though both conditions present dysfunction in the dopamine-producing neurons in the brain, the actual mechanisms, or how the neurons are affected, are not identical.

Earlier studies involved patients with advanced cases of Parkinsons disease that have been taking dopamine drugs for years, which may account for the significance of RLS. The use of dopamine drugs makes it much harder to correctly diagnose restless leg syndrome. The dopamine can cause restlessness that may be confused with RLS.

Restless Legs Syndrome And Periodic Limb Movement Disorder

Most people who have RLS also have a condition called periodic limb movement disorder . PLMD involves repetitive flexing or twitching of the limbs while asleep at night. It is different from RLS in that these movements are not accompanied by uncomfortable sensations and because they occur during sleep, patients are often not aware of them. However, PLMD-associated movements can cause a person to wake up and therefore can compound sleep issues in patients who also have RLS.

Although most people with RLS have PLMD, many with PLMD do not have RLS.

Pd And Rls: An Overview

PD is a progressive neurodegenerative disorder characterised by pathologic intraneuronal alpha-synuclein-positive Lewy bodies and neuronal cell loss. In particular, involvement of dopaminergic cells in the substantia nigra pars compacta is associated with development of the motor features of the disease. The cardinal clinical symptoms and signs of PD are bradykinesia, rigidity, tremor, postural instability and freezing attacks . The prevalence of PD increases with age, affecting 1-2% of the population over the age of 65 years, and 3% of those over 85 years . Several monogenic forms of PD and numerous genetic susceptibility factors have been identified . Sleep disturbances have been widely reported in PD, although an increased incidence of periodic leg movements of sleep is debatable, with polysomnography studies revealing mixed findings .

RLS can be associated with medical conditions such as renal failure, iron deficiency, neuropathy, and pregnancy . Family history, with an autosomal dominant mode of inheritance may be present in more than half of the cases. Five genetic loci for RLS have been reported in different pedigrees, of which 4 are autosomal dominant and one autosomal recessive . The detection of PLMS during overnight polysomnography is the the most frequent objective abnormality and can be demonstrated in the majority of RLS patients . However, the absence of PLMS does not exclude RLS .

There are many ways you can help yourself but it does depend on how disruptive the symptoms are and what changes you are willing to make.

First, review your lifestyle and see what changes you can make to reduce or eliminate RLS symptoms. Suggestions include:

  • Establish the right level of exercise – too much worsens it, too little may trigger RLS. Some people find that a few minutes of exercise just before bedtime is particularly effective, although others find that exercise in the evening worsens the symptoms.
  • Avoid stimulants, such as caffeine, alcohol and smoking, particularly in the evening.
  • Eliminate from your diet foods that trigger RLS these may include sugar, triglycerides , gluten, sugar substitutes , or following a low-fat diet. Experiment to see what works for you but before significantly changing your diet, always check with your doctor or a dietician first.
  • Create a peaceful, cool sleeping environment.
  • Discuss with your doctor adding supplements such as potassium, magnesium, B-12, folate, vitamin E, and calcium to your diet. Whilst it has not been clinically proven, there is anecdotal evidence to suggest these supplements can ease RLS symptoms.

To relieve the symptoms, you could try:

These are simply suggestions and what works for some people, wont for others. If you have any concerns talk to your doctor or healthcare professional first.
