Hypersomnia is characterized by recurrent episodes of excessive daytime sleepiness or prolonged nighttime sleep.

• Hypersomnia may be caused by another sleep disorder (such as narcolepsy or sleep apnea), dysfunction of the autonomic nervous system, or drug or alcohol abuse.
• In some cases it results from a physical problem, such as a tumor, head trauma, or injury to the central nervous system.
• Certain medications, or medicine withdrawal, may also cause hypersomnia.
• Medical conditions including multiple sclerosis, depression, encephalitis, epilepsy, or obesity may contribute to the disorder.
• Some people appear to have a genetic predisposition to hypersomnia; in others, there is no known cause.
• Typically, hypersomnia is first recognized in adolescence or young adulthood.
