RESTLESS LEGS SYNDROME AND INSOMNIA FREQUENCY IN PATIENTS WITH PSORIASIS

|December 16, 2015
Summary
Restless Legs Syndrome (RLS) is significantly more common in psoriasis patients, often leading to secondary insomnia. Early consideration of RLS and insomnia is recommended for psoriasis management.
Area of Science:
- Dermatology
- Neurology
- Sleep Medicine
Background:
- Psoriasis is a chronic inflammatory skin condition.
- Restless Legs Syndrome (RLS) is a neurological disorder characterized by an urge to move the legs.
- The relationship between psoriasis and RLS requires further investigation.
Purpose of the Study:
- To determine the prevalence and severity of RLS in patients with psoriasis.
- To explore the impact of RLS on sleep quality and overall quality of life in psoriasis patients.
- To investigate the correlation between RLS, insomnia, and psoriasis severity.
Main Methods:
- A study involving 70 psoriasis patients and 70 controls was conducted.
- RLS diagnosis and severity were assessed using International Restless Legs Syndrome Study Group (IRLSSG) criteria.
- Insomnia was diagnosed using International Classification of Sleep Disorders (ICSD-II) criteria; Psoriasis Area Severity Index (PASI) and Dermatology Life Quality Index (DLQI) were also applied.
Main Results:
- RLS was diagnosed in 40% of psoriasis patients compared to 14.2% of controls (p<0.001).
- Patients with psoriasis and RLS-induced insomnia had higher IRLSSG severity scores (p<0.001).
- Higher PASI scores were observed in psoriasis patients with insomnia (p<0.001), but DLQI scores did not differ significantly.
Conclusions:
- Psoriasis patients exhibit a significantly higher prevalence of RLS compared to the general population.
- RLS is more prevalent, though mildly severe, in psoriasis patients; secondary insomnia is correlated with RLS severity.
- Screening for RLS and insomnia is advisable in patients diagnosed with psoriasis for comprehensive care.

Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

01:27Insomnia
576
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

01:15REM Sleep Behavior Disorder
2.4K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

01:19Management of Insomnia
778
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
