Pediatric narcolepsy: How to recognize the signs in children and teens

Recognizing the symptoms of narcolepsy in children and adolescents can be more challenging than in adults, making the disease difficult to diagnose and treat at a young age.

Narcolepsy is a rare sleep disorder in which the brain can’t properly regulate the sleep-wake cycles that determine when a person should be awake and when they should be asleep.

Many people with the disorder start experiencing symptoms in childhood or adolescence. But because those symptoms are often mistaken for behavior or mood problems, the diagnosis is commonly delayed until adulthood.

Recognizing the signs of pediatric narcolepsy early can help children receive a timely diagnosis and treatment, allowing them to live as normal and active a life as possible.

Unique symptoms of narcolepsy in children

As in adults, the hallmark symptom of narcolepsy in children is excessive daytime sleepiness (EDS), an overwhelming need to sleep during the day regardless of how much nighttime sleep a child gets.

However, this symptom may look different in younger people — sleepiness does not always appear as obvious drowsiness or nodding off. Instead, EDS in children may appear as:

• taking longer naps than usual as a toddler, or consistently needing naps beyond age 5
• feeling tired even after waking from a nap
• falling asleep often during quiet activities like watching TV, sitting in class, or reading
• being forgetful or struggling to concentrate in school
• being irritable, aggressive, restless, hyperactive, or socially withdrawn

Children with EDS may also experience sleep attacks, suddenly falling asleep during daily activities. These attacks tend to last longer in children than in adults. Children may continue to perform automatic behaviors, such as writing or drawing, but are unaware of and do not remember doing so.

Other pediatric narcolepsy signs can include:

• cataplexy, a sudden loss of muscle tone, often occurring with strong emotions or stress
• sleep paralysis, an inability to move or speak for a few seconds immediately after waking up or before falling asleep
• vivid, dream-like hallucinations when falling asleep or waking up
• disturbed nighttime sleep, including waking up frequently and restless sleep
• rapid weight gain around the time when sleepiness begins
• hormonal changes and early puberty

Recognizing cataplexy in toddlers and adolescents

In adults, cataplexy often causes the knees to buckle or leads to sudden, full-body collapse. In children, it can look quite different and may be mistaken for other problems such as clumsiness, seizures, or behavioral issues.

These episodes are usually brief, and the child remains awake and aware. While cataplexy in adults is often triggered by strong emotions such as laughter or excitement, episodes in young children may occur more spontaneously and may not always have an obvious emotional trigger.

In toddlers and young children, cataplexy may resemble a movement disorder, with such potential signs as:

• changes in the facial muscles, including droopy eyelids, slack jaw, or tongue sticking out
• abnormal facial movements, including repetitive lip biting, grimacing, or chewing
• sudden loss of facial expression
• brief head drop

In adolescents, cataplexy may begin to resemble what is seen in adults. This includes:

• jaw sagging
• head dropping
• knees buckling
• dropping items, especially when excited or emotional
• feeling weak when laughing

Behavioral signs: Irritability vs. sleepiness

Childhood narcolepsy symptoms are frequently misidentified as attention-deficit/hyperactivity disorder, a mood disorder, or another behavioral problem.

That is because young people may become irritable, restless, or act out as they struggle to stay awake. Parents or teachers may notice:

• frequent meltdowns or temper tantrums
• mood swings, social withdrawal, or sadness
• restlessness or an inability to sit still
• aggression or defiance

Behavioral symptoms may become more noticeable during quiet activities when sleepiness is strongest, such as in class, during car rides, or while reading.

School performance and concentration issues

School may be one of the first places where signs of narcolepsy become obvious, as children struggle to concentrate and keep up academically. Some school-related issues that might arise with narcolepsy include:

• struggling to stay awake during class, especially during quiet activities like lectures, reading, or videos
• poor attention and distractibility
• taking longer to finish work, needing instructions repeated, or forgetting information they just received
• lower than expected academic performance or a sudden drop in grades
• difficulty socializing with peers
• more frequently missing school

It can be difficult to disentangle these issues from more common challenges affecting children and adolescents, which is in part why narcolepsy can be so hard to diagnose in young people.

Seeking a pediatric sleep evaluation

The signs of narcolepsy in teens and younger children can easily be attributed to many other conditions, and can be difficult for families to identify on their own.

If caregivers notice symptoms that persist for several months and interfere with their child’s daily activities, they should talk to their child’s pediatrician about a referral to a sleep specialist or neurologist, who can perform a thorough sleep evaluation.

This evaluation may include:

• collecting a detailed medical history
• asking parents to keep a sleep diary that tracks their child’s symptoms and sleep patterns
• having the child wear a device around their wrist that monitors movement for a few weeks
• an overnight sleep study (polysomnography), which tracks brain activity, heart rate, breathing, and movement during sleep
• a daytime nap test (multiple sleep latency test), to see how easily the child falls asleep during the day
• blood tests and brain imaging, to rule out other causes of sleepiness

A specialist can use findings from these tests to diagnose narcolepsy or other pediatric sleep disorders and develop a tailored management plan.

Not all narcolepsy medications are suitable for children, but several treatment options are available. Along with lifestyle changes such as scheduled naps and school accommodations, these treatments can help children live full and active lives.
