What is Hypersomnia



Hypersomnia is a term that refers to a collection of sleep disorders that all include having trouble staying awake during the day. 40% of people experience symptoms of hypersomnia during their lives. Common symptoms of hypersomnia include anxiety, tiredness during the day, feeling disoriented, drowsiness, hallucinations, having trouble remembering, and a loss of appetite.

Hypersomnia is very similar to a sleep disorder known as narcolepsy  which causes people to fall asleep or become very drowsy during the day due to a problem with the brains ability to manage the REM cycle. The REM cycle is a four phase process that determines how deep of a sleep you are in.

People who feel very tired, and feel like they need to go to sleep for most of the day might have hypersomnia and should get checked out by a sleep specialist or a family doctor. A sleep specialist can run tests including blood tests, polysomnograhy, an EEG, or CT scan to help determine if hypersomnia may be contributing to your daytime sleepiness.
