Causes of Excessive Sleepiness: Sleep Apnea, Narcolepsy, RLS

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Excessive sleepiness is a common issue that can significantly impact daily functioning and quality of life. This article explores the primary causes of excessive sleepiness, focusing on sleep apnea, narcolepsy, and restless legs syndrome (RLS).

Sleep Apnea

Sleep apnea is a disorder characterized by repeated interruptions in breathing during sleep. These interruptions, known as apneas, can lead to fragmented sleep and reduced oxygen levels in the blood. Obstructive sleep apnea (OSA) is the most common form, where the airway becomes blocked during sleep. Excessive daytime sleepiness is a prevalent symptom of OSA, often assessed using the Epworth Sleepiness Scale (ESS)1 2. Treatments like solriamfetol have shown efficacy in reducing daytime sleepiness in OSA patients, improving their functional status and quality of life1 2.

Narcolepsy

Narcolepsy is a chronic neurological disorder that affects the brain’s ability to regulate sleep-wake cycles. People with narcolepsy experience excessive daytime sleepiness and may fall asleep suddenly at inappropriate times. The condition is often accompanied by cataplexy, sleep paralysis, and hallucinations. Studies have demonstrated that treatments such as solriamfetol can significantly improve wakefulness and reduce sleepiness in narcolepsy patients, as measured by the ESS and other functional assessments1 2. Long-term studies confirm the maintenance of these benefits over extended periods2.

Restless Legs Syndrome (RLS)

Restless legs syndrome (RLS) is a neurological disorder characterized by an uncontrollable urge to move the legs, usually due to uncomfortable sensations. These symptoms typically occur in the evening or nighttime hours when a person is sitting or lying down, making it difficult to fall asleep and stay asleep. While RLS itself does not directly cause excessive daytime sleepiness, the resulting sleep disruption can lead to significant daytime fatigue and sleepiness.

Conclusion

Excessive sleepiness can stem from various underlying conditions, including sleep apnea, narcolepsy, and RLS. Effective management of these conditions is crucial for improving patients’ quality of life and daily functioning. Treatments like solriamfetol have shown promise in addressing excessive sleepiness in both sleep apnea and narcolepsy, highlighting the importance of targeted therapeutic interventions.
