In simple words: Recurrent hypersomnia is a condition where a person experiences episodes of excessive sleepiness that come and go. During these episodes, they might sleep for much longer than usual and have trouble staying awake.They might also have other symptoms like increased appetite, confusion, and mood changes.Between episodes, they usually sleep normally.

Recurrent hypersomnia is a sleep disorder characterized by repeated episodes of excessive sleepiness, often lasting for several days or weeks.These episodes can be accompanied by other symptoms such as hyperphagia (excessive eating), irritability, disorientation, hallucinations, and decreased libido. Between episodes, individuals typically experience normal sleep patterns and behavior.Kleine-Levin syndrome and menstrual-related hypersomnia are specific forms of recurrent hypersomnia.

Example 1: A 19-year-old male presents with recurrent episodes of excessive sleepiness lasting for 1-2 weeks, accompanied by increased appetite and confusion. He is diagnosed with Kleine-Levin syndrome, a form of recurrent hypersomnia., A 25-year-old female reports experiencing episodes of overwhelming sleepiness for several days before and during her menstrual period. She is diagnosed with menstrual-related hypersomnia., A 40-year-old individual reports episodes of excessive sleepiness lasting for several days at a time, occurring unpredictably a few times per year. After ruling out other sleep disorders and medical conditions, a diagnosis of recurrent hypersomnia is made.

Documentation should include detailed sleep history (duration and frequency of sleep episodes, associated symptoms), medical history, physical examination findings, and results of any diagnostic tests performed (e.g., polysomnography, blood work, CT scan).The documentation must support the diagnosis of recurrent hypersomnia and differentiate it from other sleep disorders and medical conditions.
