Report from the Questionnaire Report from the Observation Chart

General information

Estimated occurrence
270-500:1,000,000 inhabitants. The prevalence increased in Sweden 2009/2010 due to a side effect to Pandemrix flu vaccination.
Narcolepsy is a chronic, neurological disease caused by disruptions to the control over waking and sleeping. The disease can be primary or secondary. In cases of primary narcolepsy, the body is deficient in the orexin hormone, which controls waking and sleeping. Secondary narcolepsy is the result of another disease. Familial narcolepsy is an uncommon, hereditary variety.
General symptoms
Increased daytime sleepiness, sleep attacks that are impossible to prevent, sudden muscle weakness and sense of paralysis (cataplexies), hallucinations, disturbed night-time sleep, and paralysis (sleep paralysis) in connection with falling asleep and waking up are common. Mental ill health and weight gain can also occur.

Orofacial/odontological symptoms

Dry mouth due to medication is common. Snacking, especially at night, is also common, which increases the risk of dental caries.

Advice on follow-up and treatment

  • Early contact with dental services for intensified prophylactic care and oral hygiene information is essential.
