Hypersomnia often disrupts daily activities and impairs overall quality of life. Those affected may struggle to stay awake during work or social interactions, leading to decreased productivity and strained relationships. The condition can be caused by sleep disorders such as sleep apnea, narcolepsy, or restless leg syndrome, as well as depression or chronic fatigue syndrome. Diagnosing hypersomnia typically involves a thorough sleep evaluation, including overnight sleep studies and assessments of sleep patterns.
What is Hypersomnia?
Hypersomnia is a condition characterized by excessive daytime sleepiness (EDS) that interferes with a person’s daily activities. It is distinct from normal daytime sleepiness and can significantly impact an individual’s quality of life, leading to difficulties at work, school, or in social situations.
Hypersomnia is not simply a matter of feeling tired or sleepy during the day. It is a chronic condition that causes individuals to experience an overwhelming need for sleep, even after a full night’s rest. People with hypersomnia may find it difficult to wake up in the morning and may feel groggy and disoriented throughout the day. They may also experience difficulty concentrating, irritability, and impaired memory.1
Hypersomnia can be a primary condition, meaning that it exists on its own, or it can be secondary to another underlying medical condition. In cases of secondary hypersomnia, the excessive daytime sleepiness is a symptom of another disorder, such as narcolepsy, sleep apnea, or a neurological condition.
Excessive Daytime Sleepiness
Excessive daytime sleepiness (EDS) is a common symptom of hypersomnia and is characterized by an irresistible urge to sleep during the day, even after a full night’s sleep. It can be difficult for individuals with EDS to stay awake during the day, and they may experience brief episodes of sleep that can last for a few minutes or even several hours.
EDS can have a significant impact on a person’s daily life, leading to difficulties at work, school, or in social situations. It can also increase the risk of accidents, as individuals with EDS may have difficulty staying alert and focused while driving or operating machinery.
There are a number of factors that can contribute to EDS, including sleep deprivation, jet lag, shift work, and certain medical conditions. In some cases, EDS may be a symptom of an underlying sleep disorder, such as narcolepsy or sleep apnea.
Causes, Symptoms, and Treatments
Hypersomnia can be caused by a variety of factors, including:
- Medical conditions: Certain medical conditions, such as narcolepsy, sleep apnea, and thyroid problems, can cause hypersomnia.
- Medications: Some medications, such as antidepressants and antihistamines, can cause drowsiness as a side effect.
- Lifestyle factors: Poor sleep habits, such as irregular sleep schedules or a lack of sleep, can also lead to hypersomnia.
The symptoms of hypersomnia can vary from person to person, but may include:
- Excessive daytime sleepiness
- Difficulty waking up in the morning
- Feeling groggy and disoriented throughout the day
- Difficulty concentrating
- Irritability
- Impaired memory
Treatment for hypersomnia depends on the underlying cause. In some cases, lifestyle changes, such as improving sleep habits and avoiding caffeine and alcohol, may be enough to manage the condition. In other cases, medication or cognitive behavioral therapy may be necessary.
Diagnosing Hypersomnia
The diagnosis of hypersomnia involves a comprehensive evaluation by a healthcare provider, often a sleep specialist. This process typically begins with a detailed patient history and a discussion of symptoms, sleep patterns, and lifestyle habits. The specialist may recommend a sleep study, such as polysomnography, which records brain waves, blood oxygen levels, heart rate, and eye and leg movements during sleep.
Additionally, a Multiple Sleep Latency Test (MSLT) can be used to measure how quickly someone falls asleep in a quiet environment during the day. These tests help identify the presence of sleep disorders like sleep apnea or narcolepsy that may be contributing to excessive daytime sleepiness.2
