Narcolepsy is a rare sleep disorder. It occurs more often in older adults than in children. In narcolepsy, the brain cannot appropriately regulate: 

  • Sleep  
  • Wakefulness 

This causes severe daytime sleepiness.  

Medication can treat the symptoms of narcolepsy. It can:  

  • Improve sleep at night  
  • Increase wakefulness during the day

Behavioral changes may also help some people with narcolepsy.  

Narcolepsy is a lifelong disease with no cure.


Disorder Overview


Narcolepsy is a sleep disorder. It causes daytime sleepiness, as well as other specific symptoms including:  

  • Hallucinations 
  • Sleep paralysis 
  • Sudden muscle weakness  

Doctors classify narcolepsy into two types. They are:

Narcolepsy type 1.

  • This includes cataplexy.  
  • There may be low levels of a neurotransmitter called orexin. This is found in cerebrospinal fluid.

Narcolepsy type 2.

  • The patient is excessively sleepy during the day. This is diagnosed by specific testing.  
  • There is no cataplexy or low orexin. 
Share on social media:


Both types of narcolepsy can cause extreme daytime sleepiness. The patient may fall asleep during various daytime activities, even at dangerous times. Some people call these sleep attacks. This is because: 

  • The onset of sleep is fast. 
  • It is difficult to fight the urge to sleep.  

Daytime tiredness can cause behavioral problems, especially in children. Problems can include:  

  • Irritability 
  • Hyperactivity 
  • Aggression 

Fatigue can cause:  

  • Forgetfulness  
  • Difficulty concentrating in school  

Children with narcolepsy have an increased risk for:  

  • Depression 
  • Obesity 
  • Early puberty  

Other specific symptoms include the following:

Sleep paralysis.

  • A person with sleep paralysis is awake and aware. However, they are unable to move their entire body. They are also unable to speak.  
  • Paralysis usually occurs when falling asleep or waking. It can last up to a few minutes. It can be very upsetting. It may be difficult for a child to describe.  
  • Sleep paralysis can also happen to a person without narcolepsy.
Share on social media:

Sleep-related hallucinations.

  • A person may see, hear, or feel something that is not present. Hallucinations are intense and brief. 
  • These hallucinations usually happen just before falling asleep (hypnogogic) or just after waking up (hypnopompic). This can be a very scary experience.  
  • Sleep-related hallucinations can also happen to a person without narcolepsy.
Share on social media:


  • A person with cataplexy can have a sudden loss of muscle tone when feeling a strong emotion. For example, it can be triggered by fear, stress, excitement, anger, or laughter.  
  • Muscle weakness may involve the arms and legs. It can cause the falling or dropping of objects. It can also cause a person to fall to the ground. 
  • Cataplexy can cause isolated facial droop or head drop. In young children, the muscles of the face may be affected. This can cause eyelid drooping or a change in facial expression. Commonly, the tongue lolls out of the mouth.  
  • The child is awake and aware. The symptoms usually only last for a few seconds.
Share on social media:

Disrupted sleep.

  • People with narcolepsy often have difficulty staying asleep overnight.  
  • They typically fall asleep at the beginning of the night. However, they wake up frequently and have difficulty falling back to sleep.
Share on social media:


Narcolepsy is caused by low levels of a neurotransmitter called orexin (sometimes called hypocretin). This is found in the brain. The disease is thought to occur when the immune system destroys the brain cells that produce orexin.  

In rare cases, narcolepsy may be caused by: 

Genetic factors may increase the risk of narcolepsy. Almost all patients with narcolepsy type 1 have a variation in a specific gene. The gene is called HLA-DQB1*0602. However, this genetic variation does not cause narcolepsy. Many people with this genetic variation will never have narcolepsy.



A sleep doctor will go over a detailed history of sleep habits and symptoms of concern with children and their caregivers. They will also perform a physical exam.  Tests may include:

  • A polysomnogram (PSG, or overnight sleep study). A PSG looks for other sleep disorders, like sleep apnea, that can cause similar symptoms to narcolepsy. The electrical activity of the brain is measured along with: 
    • Breathing 
    • Heart rate 
    • Other vital signs 
  • A multiple sleep latency test (MSLT). In an MSLT, a person takes several naps. This tests to see how quickly they fall asleep. 
  • Cerebrospinal fluid testing. A small amount of fluid is collected from around the spinal cord. The amount of the neurotransmitter orexin is measured.


Treatment for narcolepsy includes both behavioral changes and medication. The following can help: 

  • Changes in sleep habits, diet, and exercise. A sleep doctor will encourage these to improve:  
    • Sleep at night  
    • Wakefulness during the day 
  • Medications to increase wakefulness (stimulants). These are often used to help with daytime symptoms.  
  • Visits with a psychologist. Some children with narcolepsy are also diagnosed with depression or anxiety. These mood disorders may improve with treatment for narcolepsy. It may be helpful to see a psychologist or psychiatrist to talk about other treatment options. 

It is important for a child’s school to know about their diagnosis. That way, they can best support the child.  

It is also important for teenagers and adults with narcolepsy to discuss driving safety.


Narcolepsy is a life-long disease. There is no cure. However, symptom severity tends to improve over time and with treatment.


Narcolepsy Network 
Founded in 1986, Narcolepsy Network is a 501(c)(3), member-led community organization based in the U.S. that works to educate, empower, and connect people impacted by narcolepsy. Through the lens of advocacy, education, awareness, and support, Narcolepsy Network delivers programs and resources in the form of clinical updates and research, webinars, support groups, and advocacy opportunities. Narcolepsy Network also hosts an annual conference offering up-to-date information on clinical research, therapies, and lifestyle hacks, as well as networking and support.
