Idiopathic Hypersomnia is a rare sleep disorder that affects a small percentage of the population. It is characterized by excessive daytime sleepiness, despite getting enough sleep at night. Read on as we discuss the causes, symptoms, and treatment options for idiopathic hypersomnia.
What is Idiopathic Hypersomnia?
Idiopathic Hypersomnia is a neurological disorder that affects a person’s ability to stay awake during the day, despite getting enough sleep at night. Unlike narcolepsy, which is characterized by sudden and uncontrollable sleep attacks, people with idiopathic hypersomnia experience excessive daytime sleepiness without the sudden onset of sleep. The condition is known as “idiopathic” because the exact cause is not known.
Causes of Idiopathic Hypersomnia
There is evidence to suggest that idiopathic hypersomnia may be inherited. Some studies have shown that people with the condition are more likely to have family members who also experience excessive daytime sleepiness.
It is believed that the brain chemistry of people with idiopathic hypersomnia is different from those without the condition. Specifically, researchers have found that people with idiopathic hypersomnia have lower levels of a chemical called hypocretin, which helps regulate wakefulness.
Hypocretin deficiency is a condition where the brain does not produce enough hypocretin. This condition is also associated with narcolepsy, but people with idiopathic hypersomnia have normal levels of hypocretin, suggesting that there may be other causes of the condition.
Symptoms of Idiopathic Hypersomnia
Excessive Daytime Sleepiness
The most common symptom of idiopathic hypersomnia is excessive daytime sleepiness, which is characterized by a persistent feeling of tiredness and the need to sleep during the day, despite getting enough sleep at night.
Difficulty Waking Up
People with idiopathic hypersomnia often have difficulty waking up in the morning. They may feel groggy or disoriented for an extended period after waking up.
Sleep inertia is a feeling of grogginess or disorientation that occurs immediately after waking up. It can last for several minutes or even hours, and it is a common symptom of idiopathic hypersomnia.
Memory and Concentration Problems
People with idiopathic hypersomnia may experience memory and concentration problems as well as having difficulty focusing or remembering things, which in turn can affect their ability to perform everyday tasks.
Diagnosis of Idiopathic Hypersomnia
Diagnosing idiopathic hypersomnia can be challenging because the symptoms are similar to other sleep disorders, such as narcolepsy. To make a diagnosis, a doctor will typically perform a physical exam and take a detailed medical history. They may also recommend a sleep study to monitor the patient’s brain activity and other physiological measures during sleep.
Treatment Options for Idiopathic Hypersomnia
While there is no cure for idiopathic hypersomnia, there are several treatment options available that can help manage the symptoms of the condition.
Stimulant medications, such as methylphenidate and amphetamines, are commonly used to treat idiopathic hypersomnia. These medications work by increasing the levels of dopamine and norepinephrine in the brain, which help promote wakefulness.
Wakefulness-promoting agents, such as modafinil and armodafinil, are also commonly used to treat idiopathic hypersomnia. These medications work by increasing the levels of certain chemicals in the brain that promote wakefulness.
Modafinil is a medication that is specifically approved for the treatment of excessive daytime sleepiness associated with narcolepsy, shift work sleep disorder, and obstructive sleep apnoea. However, it is also commonly used off-label to treat idiopathic hypersomnia.
Making certain behavioural changes can also help manage the symptoms of idiopathic hypersomnia. For example, establishing a regular sleep schedule and avoiding caffeine and alcohol can help promote better sleep at night and reduce daytime sleepiness.
Taking short, scheduled naps throughout the day can also help manage the symptoms of idiopathic hypersomnia. However, it is important to keep these naps short, as longer naps can interfere with nighttime sleep.
In some cases, establishing a strict sleep schedule may be necessary to manage the symptoms of idiopathic hypersomnia. This may involve going to bed and waking up at the same time every day, even on weekends and holidays.
