From the Guidelines
Depression can contribute to the development of restless leg syndrome (RLS), though the relationship is complex and bidirectional. Depression and RLS share common neurobiological pathways, particularly involving dopamine and serotonin dysregulation, as noted in the American Academy of Sleep Medicine clinical practice guideline 1. People with depression often experience sleep disturbances that can trigger or worsen RLS symptoms. Additionally, certain antidepressant medications, especially selective serotonin reuptake inhibitors (SSRIs) like fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil), can sometimes induce or exacerbate RLS symptoms as a side effect, as discussed in the guideline 1. This occurs because these medications can alter dopamine signaling in the brain.
Some key points to consider:
- Depression and RLS have a complex relationship, with each condition potentially exacerbating the other 1.
- Certain antidepressants, such as SSRIs, can worsen RLS symptoms, while others like bupropion (Wellbutrin) may be less likely to do so 1.
- Managing depression through therapy, stress reduction techniques, and appropriate medication can potentially help reduce RLS symptoms, while simultaneously treating RLS can improve sleep quality and potentially alleviate depressive symptoms 1.
- The American Academy of Sleep Medicine clinical practice guideline provides recommendations for the treatment of RLS, including the use of ferrous sulfate, dipyridamole, and extended-release oxycodone, among others 1.
- It is essential to discuss both depression and RLS symptoms with a healthcare provider to determine the best course of treatment, as they may consider alternative antidepressants or therapies to manage both conditions effectively 1.
- The guideline also highlights the importance of addressing exacerbating factors, such as alcohol, caffeine, and untreated obstructive sleep apnea, in the management of RLS 1.
Overall, the relationship between depression and RLS is complex, and a comprehensive treatment approach that addresses both conditions is crucial for effective management.
From the Research
Relationship Between Depression and Restless Leg Syndrome
- Depression is a common comorbidity in restless legs syndrome (RLS), with epidemiological studies reporting a 2- to 4-fold risk of depressive disorder in patients with RLS compared to healthy controls 2.
- The high prevalence of depression in RLS suggests an association between the two disorders, which may be attributed to severe sleep disturbance due to nightly RLS symptoms 2.
- The treatment of depression in RLS has unique aspects, as several antidepressants have been reported to trigger or worsen RLS symptoms 3, 2, 4.
Impact of Depression on RLS Symptoms
- Comorbid depression can substantially contribute to the emergence of depressive symptoms in RLS patients, and its presence can impact the global treatment outcome 2.
- Data from recent trials with dopamine receptor agonists indicate that mild to moderate depressive symptoms are often relieved with improvement of RLS symptoms 2.
- However, some antidepressants, such as mirtazapine, may be associated with higher rates of RLS and periodic limb movements, while others, like bupropion, may reduce RLS symptoms 4.
Treatment Considerations
- The treatment of depression in RLS requires careful consideration, as some antidepressants can exacerbate RLS symptoms 3, 2, 4.
- A therapeutic algorithm for the treatment of depression in RLS has been proposed, taking into account the complex relationship between the two disorders 3.
- Non-pharmacological therapies, such as those used in pregnancy, may also play a significant role in controlling RLS symptoms 5.
