What are the genetic and environmental factors that cause narcolepsy?

Narcolepsy is a sleep disorder that leads to excessive daytime sleepiness and sudden sleep attacks. While the exact causes of narcolepsy are currently unknown, some genetic factors and infections have been linked to an increased risk of narcolepsy. Genetic Factors: Research shows that narcolepsy occasionally runs in families, meaning it can be inherited. Also, certain genetic profiles have been linked to a higher risk of developing narcolepsy. For example, the HLA-DQB1*0602 genetic variant is found in most people with narcolepsy. Infections: Besides genetics, certain infections like the flu streptococcal infection might play a role. Summary: The exact causes of narcolepsy are not currently known, but narcolepsy has been linked to some genetic factors and certain infections. If you have questions about sleep disorders, it is important to talk to a healthcare provider for personalized medical advice.
