General Information About Hypersomnia
Disease Details and Frequently Asked Questions
It is a condition where, even if the amount of nighttime sleep is adequate, a person constantly feels sleepy throughout the day, lacks focus, and has a strong urge to fall asleep at any given opportunity.
Breathing pauses related to nighttime snoring (Sleep Apnea) are the most common cause as they disrupt sleep quality. Additionally, chronic depression, thyroid diseases, or structural disorders in the brain's sleep-wake center (Idiopathic Hypersomnia) also lead to this condition.
In narcolepsy, a person suddenly loses muscle strength (cataplexy) while talking or laughing and instantly falls asleep within seconds. In hypersomnia, there is no sudden muscle paralysis; there is only a continuous and heavy state of sleepiness and fatigue.
It is the state of extreme grogginess, confusion, and inability to transition to a fully awake (alert) state that hypersomnia patients experience when waking up in the morning or from a daytime nap.
Initially, thyroid and vitamin tests are conducted. A definitive diagnosis is made with Polysomnography (PSG), where the patient stays overnight in a sleep lab to measure brain and respiratory waves, and the MSLT test, which measures the time it takes to fall asleep during the day.
If the cause is sleep apnea, a CPAP (oxygen mask) machine is provided; if the cause is depression, psychiatric treatment is applied. In cases where the cause cannot be found (idiopathic), doctor-controlled central nervous system stimulant medications (like modafinil) are used to keep the patient awake and alert throughout the day.
