new Study published in JAMA Network Open Find out if people with restless legs syndrome (RLS) are more likely to develop Parkinson’s disease (PD). The findings suggest that having restless legs syndrome may increase your risk, but treatment can play a key role.
What is restless legs syndrome?
Restless legs syndrome It is a neurological sleep disorder in which people feel the desire to move their legs. There can also be uncomfortable sensations, often described as crawling, crawling or itching. These sensations usually get worse in the evening or at night. People with restless legs syndrome often have difficulty falling asleep or staying asleep. Symptoms may temporarily ease when they move their legs, stretch, or walk around.
the Causes of RLS It may vary from person to person. It can be related to low iron levels, diabetes, kidney failure, pregnancy, or certain medications.
RLS It may also be related – A defect in the part of the brain that controls movement. This part of the brain uses a chemical called dopamine to create smooth muscle movement. When dopamine levels are disrupted, it may lead to involuntary movements.
Restless legs syndrome is diagnosed by your doctor based on a description of your symptoms. No blood, radiation, or sleep test is necessary to diagnose restless legs syndrome.
For people with severe symptoms, prescription medications can help. Some of the most common treatments affect the brain’s dopamine system, including medications such as pramipexole, ropinirole, rotigotine, and levodopa. These dopamine agonists were once considered the gold standard for restless legs syndrome, but have recently been updated Clinical practice guidelines The American Academy of Sleep Medicine recommends that it not be used routinely due to potential side effects and long-term complications. There are other prescription medications that can treat restless legs syndrome that work on the dopamine, GABA, or opioid receptor systems.
Parkinson’s disease and dopamine
Parkinson’s disease It is a progressive disorder of the nervous system that affects movement. It develops when nerve cells in the brain weaken and die, leading to tremors, stiffness, slow movement, and balance problems. As the disease progresses, people may have difficulty walking, speaking, or completing daily tasks.
In Parkinson’s disease, the brain gradually loses dopamine, a chemical that helps control movement. Since both PD and RLS involve changes in dopamine, this may help explain why they cause similar movement problems and respond to some of the same treatments.
What the study found
Researchers in South Korea examined health data on nearly 20,000 people, including 9,919 with restless legs syndrome and a similar number without it. The average age of both groups was 50 years, and about 63% were women.
Over time, Parkinson’s disease develops in 1% of people without restless legs syndrome and 1.6% of people with restless legs syndrome. This means that patients with restless legs syndrome were more likely to develop Parkinson’s disease than those without the sleep disorder.
The study also looked at how medication affects this risk. People with restless legs syndrome who were not treated with dopamine agonists were more likely to develop Parkinson’s disease and tended to be diagnosed earlier. However, those who took dopamine agonists were less likely to develop Parkinson’s disease and be diagnosed later, suggesting that treatment may play a role.
Sleep disorders and Parkinson’s disease
Restless legs syndrome is not the only sleep disorder associated with Parkinson’s disease. Rapid eye movement sleep behavior disorder RBD, a sleep disorder in which people physically act out their dreams, is also associated with an increased risk of developing borderline personality disorder later in life. In fact, RBD is sometimes viewed as an early warning sign of Parkinson’s and other neurological diseases.
Ready meals
While restless legs syndrome and Parkinson’s syndrome are two different neurological disorders, they share some similarities, including abnormal muscle movements and changes in brain activity that affect movement. Both too linked to Low dopamine levels.
Research indicates RLS is more common in people with PD. One study found that about 16% of people with Parkinson’s disease also have restless legs syndrome, compared with about 5% to 10% of the general population.
The new study adds to growing evidence that restless legs syndrome may be linked to an increased risk of developing Parkinson’s disease later in life. However, studies on this topic have shown mixed results, in part because the way both conditions are diagnosed has changed over time.
Researchers continue to study the links between the two and whether early recognition and care can help improve outcomes in the future. Both restless legs syndrome and Parkinson’s disease can interfere with sleep, so if you have persistent problems sleeping, talk to a sleep specialist or see a doctor. Certified sleep center To help.
