Summary
This study found a significantly higher prevalence of fibromyalgia syndrome in patients with sleep disordered breathing. The findings suggest a strong association between these two conditions, warranting further investigation into sleep disordered breathing as a potential factor in fibromyalgia.
Area of Science:
- Sleep Medicine
- Rheumatology
- Clinical Research
Background:
- Sleep disordered breathing (SDB) affects a significant portion of the population.
- Fibromyalgia syndrome (FMS) is a chronic condition characterized by widespread pain and fatigue.
- The relationship between SDB and FMS requires further elucidation.
Purpose of the Study:
- To investigate the prevalence of fibromyalgia syndrome (FMS) in patients diagnosed with sleep disordered breathing (SDB).
- To explore a potential association between SDB and FMS.
Main Methods:
- Fifty patients presenting to a sleep disorder clinic for symptoms like snoring, apnea, and excessive daytime sleepiness were enrolled.
- Sleep disordered breathing was diagnosed using polysomnography.
- Fibromyalgia syndrome diagnosis was based on the American College of Rheumatology criteria.
Main Results:
- Out of 50 patients (32 male, 18 female), 11 met the criteria for fibromyalgia syndrome (9 women, 2 men).
- The mean apnea-hypopnea index was 36 +/- 29 events/hour, indicating moderate to severe SDB.
- The prevalence of FMS in this SDB patient group was substantially higher than in the general population.
Conclusions:
- The study observed a more than tenfold higher proportion of fibromyalgia cases in patients with sleep disordered breathing compared to the general population.
- These findings support a hypothesis linking sleep disordered breathing and fibromyalgia syndrome.
- Further research is recommended to understand the underlying mechanisms of this association.

01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

01:17Other Pulmonary Disorders
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
01:15REM Sleep Behavior Disorder
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.

01:27Restless Leg Syndrome and Night Terrors
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...

01:24Sleep-Wake Cycles
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).

01:17Sleepwalking and Sleep Talking
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...
