Types of Hypersomnia?

Hypersomnia can be primary or secondary.

Primary hypersomnia occurs with no other medical conditions present. The only symptom is excessive fatigue.

Secondary hypersomnia is caused by other medical conditions. These can include sleep apnea, Parkinson's disease, kidney failure, and chronic fatigue syndrome, as well as others. These conditions cause poor sleep at night, so patients feel tired during the day.

Hypersomnia is not narcolepsy, which causes unexpected and uncontrollable napping. Hypersomniacs can stay awake on their own, but they feel fatigued.
