Difference between Sleep Apnea and Narcolepsy

Sleep apnea and narcolepsy are two sleep disorders that are often confused with each other. However, there are some key differences between the two conditions. In this article, we will take a closer look at the difference between sleep apnea and narcolepsy, including the symptoms of each disorder and how they are treated.

What is Sleep Apnea?

Sleep apnea is a condition in which a person experience pauses in their breathing or shallow breaths while sleeping. These pauses can last for several seconds to minutes and can occur dozens to hundreds of times per night. Sleep apnea often goes undiagnosed because it typically occurs during sleep, when people are not aware of their breathing patterns. However, sleep apnea can lead to daytime fatigue, headaches, and difficulty concentrating. It can also increase the risk of developing high blood pressure and other cardiovascular problems. While there is no cure for sleep apnea, there are treatments that can help to manage the condition. These include Continuous Positive Airway Pressure (CPAP) therapy, lifestyle changes, and mouthpieces or dental appliances. Sleep apnea is a serious condition that can have significant implications for both physical and mental health.

What is Narcolepsy?

Narcolepsy is a neurological disorder that affects the brain’s ability to control sleep-wake cycles. People with narcolepsy tend to experience excessive daytime sleepiness and may fall asleep suddenly and without warning. Narcolepsy can also cause sleep paralysis, which is a temporary paralysis of the body that occurs when falling asleep or waking up. Narcolepsy is thought to be caused by a deficiency of the neurotransmitter hypocretin, which is involved in regulating sleep-wake cycles. Narcolepsy is a chronic condition that currently has no cure. However, treatment can help to manage symptoms and improve quality of life.

Difference between Sleep Apnea and Narcolepsy

Sleep apnea and narcolepsy are two conditions that affect the quality of sleep. Sleep apnea refers to a condition in which a person experiences frequent pauses in breathing while they are sleeping, typically causing them to wake up multiple times each night. On the other hand, narcolepsy is characterized by intense feelings of sleepiness throughout the day, even during activities that would typically keep someone alert. Although the symptoms of these disorders may be similar, the causes are quite different. Sleep apnea can be caused by structural problems in the airway or abnormalities in brain activity that disrupt normal breathing patterns during sleep. In contrast, narcolepsy is often associated with specific genes that can interfere with normal sleep cycles and trigger excessive daytime sleepiness. Thus, while these two conditions may look similar on the surface, they have very different underlying causes and require distinct treatments.


Although sleep apnea and narcolepsy are both sleeping disorders, they have different causes and effects. If you think you might be suffering from one of these conditions, it is important to get an accurate diagnosis and treatment plan.
