What Is Narcolepsy?
Narcolepsy is a condition that causes excessive sleepiness, sleep paralysis, and hallucinations. Certain actions such as laughing too hard can cause cataplexy, a partial loss of muscle control. Those with narcolepsy can fall asleep at any time which has a huge impact on quality of life.
Medical Definition of Narcolepsy
The Mayo Clinic defines narcolepsy as a chronic sleep disorder. Narcolepsy symptoms cause intense daytime sleepiness and sudden bouts of sleep. People who suffer narcolepsy find it difficult to stay awake for long periods of time. Narcolepsy has no cure but can be managed with lifestyle changes and medications.
Narcolepsy is caused by low levels of hypocretin, a chemical that promotes wakefulness and regulates REM sleep.
Types of Narcolepsy
Narcolepsy with Cataplexy
Cataplexy is the sudden loss of muscle control, in the face, arms, torso, or legs. Those with narcolepsy can experience an episode of slurred speech, sagging jaw, and slump down in their seat for up to two minutes. These episodes are usually triggered by a strong emotion such as laughter.
Narcolepsy without Cataplexy
The typical narcolepsy symptoms of excessive sleepiness, sleep paralysis, and hallucinations can be experienced without cataplexy and is considered to be less severe than narcolepsy with cataplexy.
Symptoms of Narcolepsy
- Excessive daytime drowsiness and suddenly falling asleep
- Bouts of loss of muscle tone in face, jaw, arms, and torso for up to 2 minutes, slumping into chair
- Sleep paralysis and nightmares
- Changes in sleep cycles and REM frequency
What Causes Narcolepsy?
Narcolepsy is caused by low levels of hypocretin, a chemical that promotes wakefulness and regulates REM sleep. Coupled with this, there are secondary medical conditions that may cause narcolepsy such as, autoimmune disorders, brain injuries, or it is inherited.
How Is Narcolepsy Diagnosed?
A narcolepsy test in the form of a clinical examination and full medical history is typically enough to diagnose narcolepsy. Patients are asked to keep a sleep journal for up to two weeks, documenting their sleep times and experiences. Narcolepsy has one defining symptom that is not seen in any other medical conditions. Cataplexy, a sudden loss of muscle tone in the face, arms, legs, or torso.
Narcolepsy test include:
- Polysomnogram (sleep study) an overnight recording of brain, muscle activity, eye movements, and breathing. A PSG tells your doctor if you have a healthy cycle of REM sleep or if you have sleep apnea
- Multiple Sleep Latency Test that examines daytime sleepiness. An MSLT measures how fast you fall asleep and if you enter REM sleep or not. During the test, you take 5 short naps over one day, if you fall asleep within 8 minutes this is considered excessive daytime sleepiness, if you enter REM sleep within the first 15 minutes 2 times out of 5, narcolepsy is diagnosed
Anyone who suspects they may have narcolepsy should see their doctor immediately. A doctor may suggest one or more of the following treatment options.
Treatment for Narcolepsy: Medications
- Modafinil - central nervous system stimulant
- Stimulants like amphetamines if Modafinil does not work
- Antidepressants - produce less adverse symptoms than amphetamines and can ease cataplexy symptoms
- Sodium oxybate (GHB or gamma hydroxybutyrate) - a strong sedative to be taken twice per night
Treatment for Narcolepsy: Lifestyle Changes
- Exercise every day to promote sleepiness at night and to control your weight
- Enjoy fresh air every day
- Find ways to ease stress, medication, yoga, etc
- Avoid caffeine or alcohol before bedtime
