Is restless legs part of anxiety?

Restless legs syndrome (RLS) is a neurological disorder characterized by an uncontrollable urge to move the legs, often accompanied by uncomfortable sensations. Anxiety disorders, on the other hand, are mental health conditions characterized by excessive worry, fear, and apprehension. While these two conditions may seem unrelated at first glance, there is growing evidence to suggest a connection between restless legs and anxiety disorders. In this blog post, we will explore the relationship between restless legs and anxiety, their shared symptomatology, underlying mechanisms, diagnostic tools, treatment approaches, and management strategies for individuals experiencing co-occurring restless legs and anxiety.

Relationship between Restless Legs and Anxiety

A significant association has been observed between anxiety disorders and restless legs syndrome. Research studies have reported a higher prevalence of restless legs in individuals with anxiety disorders compared to the general population. It is estimated that a substantial percentage of individuals with anxiety disorders also experience restless legs. This suggests that there may be a common underlying factor contributing to the co-occurrence of these two conditions.

Furthermore, there is evidence to suggest a link between restless legs and the physiological aspects of anxiety. Both conditions involve dysregulation of the nervous system, particularly the autonomic nervous system and the neurotransmitters involved in its functioning. Disturbances in the balance of neurotransmitters such as dopamine, serotonin, and gamma-aminobutyric acid (GABA) have been implicated in both restless legs and anxiety disorders. These imbalances may contribute to the onset and exacerbation of symptoms in both conditions.

Symptomatology of Restless Legs and Anxiety Disorders

To understand the relationship between restless legs and anxiety, it is important to consider their respective symptomatology. Restless legs syndrome is characterized by an irresistible urge to move the legs, often accompanied by uncomfortable sensations such as tingling, crawling, or aching. These sensations are typically worse at rest and are alleviated by movement. On the other hand, anxiety disorders are primarily characterized by excessive worry, fear, and apprehension. Symptoms of anxiety disorders may include restlessness, irritability, difficulty concentrating, sleep disturbances, and muscle tension.

It is worth noting that some individuals with restless legs syndrome may experience anxiety as a result of the distress caused by their symptoms. The constant need to move their legs and the associated discomfort can lead to heightened levels of anxiety. Conversely, individuals with anxiety disorders may experience physiological symptoms that mimic restless legs, such as muscle twitching or restlessness. This can further complicate the diagnosis and management of these conditions.

Mechanisms underlying the connection

The exact mechanisms underlying the connection between restless legs and anxiety are still not fully understood. However, several theories have been proposed to explain this relationship. One theory suggests that abnormalities in brain activity and function contribute to both restless legs and anxiety disorders. Studies have shown that individuals with restless legs may have altered cortical and subcortical brain activity, which could be associated with anxiety symptoms. Additionally, genetic factors are believed to play a role in both conditions, although the specific genes involved are yet to be identified.

It is also thought that neurotransmitter imbalances may contribute to the co-occurrence of restless legs and anxiety. Dopamine, in particular, has been implicated in both conditions. Dopamine dysfunction is believed to play a central role in restless legs, as dopamine agonists have proven to be effective in its treatment. Similarly, imbalances in dopamine have been linked to anxiety disorders. Other neurotransmitters, such as serotonin and GABA, may also be involved in the relationship between restless legs and anxiety.

Diagnostic and Assessment Tools

Proper diagnosis and assessment of both restless legs syndrome and anxiety disorders are essential for effective management. While there are no specific laboratory tests to diagnose restless legs, healthcare professionals may rely on clinical evaluations and patient-reported symptoms. The International Restless Legs Syndrome Study Group provides diagnostic criteria that include the presence of an urge to move the legs, uncomfortable sensations, worsening of symptoms at rest, and improvement with movement.

For the assessment of anxiety disorders, healthcare professionals may use validated questionnaires such as the Hamilton Anxiety Rating Scale or the Generalized Anxiety Disorder 7 (GAD-7) scale. These tools help assess the severity of anxiety symptoms and monitor treatment progress over time.

Treatment Approaches

The treatment of restless legs and anxiety disorders typically involves a multimodal approach that combines pharmacological interventions, psychotherapy, and lifestyle modifications.

Pharmacological interventions for restless legs may include dopamine agonists, opioids, or anticonvulsant medications. These medications aim to alleviate the uncomfortable sensations and improve sleep quality. For anxiety disorders, selective serotonin reuptake inhibitors (SSRIs), benzodiazepines, or other anxiolytic medications may be prescribed to reduce symptoms of anxiety.

Psychotherapy, particularly cognitive-behavioral therapy (CBT), is a common approach used in the treatment of anxiety disorders. CBT helps individuals identify and challenge negative thought patterns and develop coping strategies to manage anxiety. This form of therapy may also be beneficial for individuals experiencing anxiety related to their restless legs symptoms.

In addition to medication and therapy, lifestyle modifications can also play a significant role in the management of both restless legs and anxiety disorders. Regular exercise, stress reduction techniques, and maintaining a consistent sleep routine may help alleviate symptoms and improve overall well-being.

Management Strategies for Co-occurring Restless Legs and Anxiety

When an individual experiences co-occurring restless legs and anxiety, a comprehensive treatment plan that addresses both conditions is necessary. Integrated treatment approaches that combine interventions for restless legs and anxiety disorders are often utilized.

Addressing the underlying anxiety disorder is crucial in managing the symptoms of both conditions. By managing anxiety symptoms, individuals may experience a reduction in the severity of their restless legs symptoms. This can be achieved through a combination of medication, therapy, and lifestyle modifications tailored to the individual’s needs.

Additionally, treating restless legs syndrome directly can also help alleviate anxiety symptoms. Effective management of restless legs symptoms through medication and lifestyle modifications can lead to improved sleep quality and reduced discomfort, ultimately reducing anxiety and improving overall quality of life.


In conclusion, restless legs syndrome and anxiety disorders share a complex relationship. Restless legs can be a symptom of anxiety disorders, and individuals with anxiety disorders may experience symptoms that resemble restless legs. The precise mechanisms underlying this connection are not yet fully understood, but neurotransmitter imbalances and abnormalities in brain activity are thought to play a role. Proper diagnosis and assessment are essential to guide treatment, which may involve a combination of medication, psychotherapy, and lifestyle modifications. By addressing both restless legs and anxiety, individuals can find relief from their symptoms and improve their overall well-being.
