Do you have periodic limb movements while you sleep? Is this the cause? Let's learn about Periodic Limb Movements of Sleep (PLMS)?

You may have heard, or experienced it yourself, that some people have sudden jerks or jerks of their arms or legs while they sleep. Sometimes your bed partner may tell you, "You just thrash around at night." So, is this just a passing fancy, or is there a medical reason behind it? That's what we're going to talk about today. We call this condition `(Periodic Limb Movements of Sleep)` or `(PLMS)` for short.

What exactly is PLMS, this jerking of limbs during sleep?

Simply put, `(Periodic Limb Movements of Sleep)` or `(PLMS)` is a movement disorder that occurs during sleep. In this case, your arms and/or legs move repeatedly without you realizing it while you are sleeping. These movements can disrupt your sleep. Some people also call this condition `(sleep-related myoclonus syndrome)` or `(nocturnal myoclonus syndrome)`. Most of the time, these movements occur in your legs. Imagine, your big toe is pointing up, while your ankle, knee, and hip are bending. However, in some cases, these movements can also be seen in your arms. This condition called PLMS is often seen together (between 80% and 90% of cases) with the discomfort in your legs called `(Restless Legs Syndrome).` Not only that, it can also be associated with other medical conditions. Here are a few examples:

• `(Obstructive Sleep Apnea)` ( Sleep apnea )
• Narcolepsy (a condition in which you suddenly fall asleep)
• `(REM sleep behavior disorder)` (abnormal behavior during a certain stage of sleep)
• `(Uremia)` (accumulation of waste products in the blood due to kidney failure)
• Spinal Cord Tumor
• `( ADHD )` (Attention Deficit Hyperactivity Disorder )

PLMD and PLMS: Do you know exactly what the difference is between the two?

You may be confused when you hear these two names: `(Periodic Limb Movement Disorder - PLMD)` and `(Periodic Limb Movements of Sleep - PLMS)`. Although the symptoms of both are similar, there is a slight difference between the two. Doctors call these movements `(PLMD)` when no other underlying medical condition can be found that causes these movements. That is, when the cause of these movements is unknown. However, when these movements occur together with another medical condition (like `(Restless Legs Syndrome)` that we discussed earlier), then doctors call it `(PLMS)`. `(PLMD)` is a rare condition. However, `(PLMS)` is more common.

How common is this condition called PLMS?

Researchers estimate that both conditions, called PLMD and PLMS, affect between 4% and 11% of adults and 5% and 8% of children. These limb movements are common in sleep studies.

Do you have PLMS? Check out these symptoms

People with PLMS usually seek medical advice because they have sleep problems. What are they?

• Excessive fatigue or sleepiness during the day.
• Insomnia.

A person with either `(PLMS)` or `(PLMD)` may have their limbs jerk or move at intervals of 20 to 40 seconds during sleep. The important thing is that most of the time, these people do not feel that they are moving in this way. However, their bed partner may say something like, "You are kicking your legs at night." Some people with `(PLMS)` may wake up frequently from sleep because of these movements, and may also have difficulty falling asleep.

Why does this PLMS occur? What are the causes?

Researchers still don't know exactly what causes PLMS. They think it's because of a problem or abnormality in our spinal cord that causes these uncontrollable movements during sleep. However, there are some medications that can make PLMS worse. Some of these medications include:

• Some types of antidepressants: For example, Mirtazapine, Venlafaxine, Sertraline, Fluoxetine, and Amitriptyline.
• Antihistamines are medicines given for some allergies.
• Medicines given for certain mental illnesses (Antipsychotics / Neuroleptics)

Who is more likely to develop PLMS? (Risk factors)

If you have any of the following conditions or habits, you may be at increased risk of developing PLMS:

• A lack of hemoglobin in the blood, that is, anemia .
• Being 65 years of age or older.
• Diabetes -related neuropathy.
• If someone in your family has `(Restless Legs Syndrome)`, `(PLMS)` or `(PLMD)`.
• Obesity .
• Not being physically active.
• Smoking .

How do you know for sure if you have PLMS?

Doctors diagnose this condition called Periodic Limb Movements of Sleep (PLMS) based on your medical history and the results of an overnight sleep study called a polysomnogram. A polysomnogram is a test that records how your body's various systems (such as your heart, brain, and respiratory system) work while you sleep. Sensors are used to do this. If an adult moves their limbs more than 15 times per hour, or a child moves their limbs more than 5 times per hour, doctors diagnose PLMS. Doctors only diagnose PLMD if they can't find another underlying cause for these movements (such as sleep apnea or restless legs syndrome). A polysomnogram can also check for a number of related conditions. Your doctor may also order additional tests, such as blood tests, to check for other causes.

What treatments can be done for PLMS?

To be honest, there is no specific treatment for `(PLMS)` itself. However, doctors usually prescribe medications that are used to treat `(Restless Legs Syndrome)`. Because that condition is associated with `(PLMS)`, those medications may also be effective. Here are some such medications:

• `(Pramipexole)`
• `(Ropinirole)`
• `(Rotigotine)`
• `( Gabapentin )`
• `(Pregabalin)`

Researchers are currently studying several other medications to treat PLMS:

• `(Clonazepam)`
• `(Melatonin)`
• `(Valproate)`
• `(Selegiline)`

Important: If you think your PLMS is getting worse because of an antidepressant or other medication you are currently taking, your doctor may recommend switching to a different type of medication. Never stop taking your medication without talking to your doctor.

Is there a way to prevent these PLMS from occurring?

Since the exact cause of PLMS is not yet known, there is no known way to prevent it. However, managing the risk factors we discussed earlier (e.g., quitting smoking, being physically active) can reduce the risk of developing the condition.

What are the long-term effects of PLMS?

PLMS can affect your sleep quality. It can also disrupt the sleep of your partner. There isn't much research on the long-term effects of PLMS. However, some studies show that people with sleep-related movement disorders (such as PLMS) are more likely to have high blood pressure. This can increase your risk of stroke and heart attack in the future. It's important to talk to your doctor about how to manage this risk.

If you have PLMS, when should you see a doctor?

If you have `(PLMS)`, it's a good idea to see a doctor if:

• If you develop new symptoms, or if your existing symptoms get worse.
• If you are experiencing unpleasant side effects from your treatment for `(PLMS)`.

Is there a link between PLMS and Parkinson's disease?

People with Parkinson's disease (PD) may experience periodic limb movements (PLMS) during sleep as part of their condition. However, there is currently no research evidence to suggest that either PLMS or PLMD are an early sign of Parkinson's disease. So don't be alarmed.

Is PLMS a disease related to the nervous system?

Yes, researchers believe that `(PLMS)` is a neurological disorder. This is because it is thought to be caused by a problem in our spinal cord - a part of our nervous system. If you are having trouble sleeping, or if you feel tired even after sleeping well, it is important to talk to a doctor. Because good quality sleep is essential for our overall health. Your problem may not be caused by `(Periodic Limb Movements of Sleep - PLMS)`. However, your doctor will do the necessary tests to confirm it. If you have any questions, never hesitate to ask your doctor. They are there to help you.

The take-home message from this story is

Okay, so now you have a better understanding of what we talked about today, `(Periodic Limb Movements of Sleep - PLMS)`. Remember, if you feel like you are moving your limbs in your sleep at night, or if your partner says so, it is best to talk to a doctor about it.

Good sleep is essential for a healthy life, so don't underestimate sleep-related problems.

I hope you found this information useful. May you and your loved ones have a healthy and comfortable sleep!
