Every day with Narcolepsy raises a new question

What is narcolepsy?

Narcolepsy is a chronic neurological sleep disorder that affects the brain’s ability to regulate sleep and wakefulness. It can cause excessive daytime sleepiness and sudden episodes of sleep.

What are the main symptoms of narcolepsy?

Common symptoms include excessive daytime sleepiness, sudden sleep attacks, disrupted nighttime sleep, sleep paralysis, vivid hallucinations around sleep, and, in some people, cataplexy.

What is cataplexy?

Cataplexy is a sudden, temporary loss of muscle control triggered by strong emotions such as laughter, excitement, surprise, or anger. A person remains conscious during an episode.

What causes narcolepsy?

Narcolepsy type 1 is associated with low levels of hypocretin (also called orexin), a brain chemical involved in regulating wakefulness. The exact cause is not fully understood, but genetic, immune, and environmental factors may contribute.

Are there different types of narcolepsy?

Yes. Narcolepsy is generally divided into type 1 and type 2. Type 1 involves cataplexy and/or low hypocretin levels, while type 2 typically occurs without cataplexy.

How is narcolepsy diagnosed?

Diagnosis usually involves an evaluation by a sleep specialist, a review of symptoms and sleep history, and sleep studies such as overnight polysomnography followed by a Multiple Sleep Latency Test (MSLT).

Can narcolepsy be cured?

There is currently no cure for narcolepsy, but symptoms can often be managed effectively with medication, planned sleep schedules, daytime naps, and lifestyle adjustments.

How does narcolepsy affect everyday life?

Narcolepsy can interfere with work, education, driving, social activities, and daily routines because of unpredictable sleepiness. Appropriate treatment and accommodations can substantially improve daily functioning.

Is narcolepsy the same as simply being very tired?

No. Narcolepsy is a neurological sleep disorder, not ordinary tiredness or sleep deprivation. People with narcolepsy can experience severe daytime sleepiness even when they have had adequate time to sleep.

When should someone see a doctor about possible narcolepsy?

Someone should consider speaking with a healthcare professional if persistent daytime sleepiness, uncontrollable sleep episodes, cataplexy, sleep paralysis, or other sleep-related symptoms are interfering with daily life.

What are the symptoms of narcolepsy?

Common symptoms include excessive daytime sleepiness and an overwhelming urge to sleep during the day.

Some people also experience cataplexy, sleep paralysis, vivid dream-like hallucinations when falling asleep or waking, and disrupted nighttime sleep.

Symptoms vary from person to person and can affect concentration, memory, mood and the ability to stay alert during everyday activities.

Who is at risk of developing narcolepsy?

Narcolepsy can affect anyone, but symptoms often begin in childhood, adolescence or early adulthood. Some people experience symptoms for years before receiving a diagnosis.

Having a family history of narcolepsy may slightly increase risk, although most people with narcolepsy do not have a close relative with the condition.

Delayed diagnosis or poorly controlled symptoms can affect education, work, emotional wellbeing and safety.

How is narcolepsy diagnosed?

Diagnosis usually starts with a discussion of symptoms, sleep habits and medical history. Doctors may use an overnight sleep study called polysomnography, followed by a multiple sleep latency test (MSLT) to assess how quickly someone falls asleep during the day and when REM sleep occurs.

Sleep diaries or actigraphy may also be used. In certain cases, testing hypocretin levels may help support a diagnosis of narcolepsy type 1.
