Narcolepsy
Unexpected sleepiness can make your day difficult to plan. Learn what narcolepsy means, why specialist assessment matters, and how to ask for support around your own activities.
A condition of sleep-wake regulation.
Narcolepsy is a neurological condition affecting regulation of sleep and wakefulness. Excessive daytime sleepiness can occur alongside disturbed sleep at night; sleeping poorly at night does not exclude it.
Cataplexy is a sudden loss of muscle strength that can happen with emotion in some people with narcolepsy. It is not present in everyone. Different types require clinical evaluation, rather than a type assigned from one symptom.

Staying awake and unexpected sleep episodes

Sleep disruption and other sleep experiences

History and appropriate sleep investigations
- Your activities
Safety and support around your own day
Changes to describe, rather than a checklist to pass.
These experiences can be part of narcolepsy, but none establishes the cause of your sleepiness on its own.
Staying awake
Strong daytime sleepiness or unexpectedly falling asleep.
Muscle weakness
Episodes of muscle weakness that you want medically assessed.
Sleep transitions
Vivid experiences around falling asleep or waking, or sleep paralysis.
Your nights
Broken night-time sleep alongside difficulties staying awake by day.

What a sleep specialist may investigate.
Assessment includes your history and an evaluation of other possible sleep or medical explanations. A specialist may arrange overnight polysomnography and a multiple sleep latency test; the appropriate investigations depend on your circumstances.
The Epworth Sleepiness Scale describes usual daytime dozing in an adult questionnaire. It does not diagnose narcolepsy, explain the cause or establish safe driving. Its owner requires a licence for use, so there is no online ESS questionnaire on this page.

- 1Your daytime experience
Give one example of unexpected sleepiness and its effect.
- 2Your nights and other changes
Mention disrupted sleep or episodes of weakness if relevant.
- 3Your safety questions
Ask about driving, work and the next assessment step.
Ask how the sleep specialist will investigate the concern.
Narcolepsy assessment considers sleepiness, other experiences and relevant history, with sleep testing when appropriate. Different tests answer different questions; not everyone needs every possible investigation.
You can ask what a proposed test measures and how to prepare. A general sleepiness questionnaire cannot diagnose narcolepsy, determine its type or provide driving clearance. Do not try to provoke weakness or a sleep episode to see whether a description fits.

Plan support around your safety and activities.
Explore the options and ask what fits your circumstances and needs.

Care can include the ordinary activities you want to do.
Specialist treatment and sleep-management support are adapted to the person. Discuss work or study, travel and safety-sensitive tasks as well as symptoms. Ask how to raise persistent difficulties or unwanted treatment effects.
A supporter may help with an agreed practical task or appointment. You can ask about adjustments without accepting a stereotype that narcolepsy always looks like a dramatic collapse.
Participation
What work, study or activity needs an adjustment?
Safety
Which risks and local requirements should we discuss?
Review
Who can help if the current plan is not meeting my needs?

You deserve to understand your care.
Daytime sleepiness has several possible explanations; a questionnaire cannot establish narcolepsy.
Your specialist assessment
Find support. Prepare your next step.
Find care or prepare a conversation. You can ask for help before you have a diagnosis.
Your first sentence does not need to be perfect.
Contact a medical professional about persistent daytime sleepiness or unexpected sleep episodes. You can ask whether a sleep-service referral is appropriate and what to do safely while waiting.

“I am struggling to stay awake during the day. Could we assess the cause and discuss a sleep-specialist referral and safe activities?”Make it sound like you
Your questions, with room for nuance.
You can read just the answer you need.
Does everyone with narcolepsy have cataplexy?
No. Experiences and types differ. A specialist considers symptoms and test results; absence of one feature or recognition of another is not an online diagnostic rule.
