narcolepsy
Let an agent explain narcolepsy in general terms, relay types, mechanisms, diagnosis, management and driving considerations from sleep medicine sources, point people to sleep specialists and advise against driving when sleepy, describe the named forms, and distinguish narcolepsy from idiopathic hypersomnia, sleep apnoea, epilepsy and insufficient sleep, without diagnosing individuals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain narcolepsy in general terms, relay types, mechanisms, diagnosis, management and driving considerations from sleep medicine sources, point people to sleep specialists and advise against driving when sleepy, describe the named forms, and distinguish narcolepsy from idiopathic hypersomnia, sleep apnoea, epilepsy and insufficient sleep, without diagnosing individuals.
A chronic neurological sleep disorder characterised by excessive daytime sleepiness and disrupted regulation of sleep and wakefulness, classified as narcolepsy type 1, with cataplexy, sudden muscle weakness triggered by emotions such as laughter, and usually low hypocretin or orexin levels linked to loss of hypothalamic neurons, and narcolepsy type 2, without cataplexy; other symptoms include sleep paralysis, hypnagogic hallucinations and fragmented night sleep. It is diagnosed with sleep studies including the multiple sleep latency test, managed with scheduled naps and medicines, and affects driving safety, and an increase in cases followed the Pandemrix H1N1 vaccine in some European countries in 2009 to 2010, as studies reported.
What it is for: Not applicable; a sleep disorder.
It can be explain types and mechanisms; relay diagnosis and management in general terms; describe cataplexy; relay driving safety.
Distinguishing features
Excessive daytime sleepiness
Cataplexy in type 1
Hypocretin loss
REM sleep intrusions
What it looks like
Not visible; noticed as sudden sleep episodes or collapses of muscle tone with emotion.
Physical character
prevalence: about 25-50 per 100,000 people - estimates vary
hypocretin discovery link: 1999-2000 years
Pandemrix association: 2009-2010 years - reported in some countries
How it is recognised
Chronic disorder of sleep-wake regulation
Cataplexy, narcolepsy without cataplexy, narcolepsy-cataplexy syndrome, narcolepsy type 1, narcolepsy type 2
Idiopathic hypersomnia lacks REM features; sleep apnoea involves breathing pauses; epilepsy involves seizures; insufficient sleep resolves with rest
