So if you’re tired of feeling lost and disoriented upon waking up, read on to discover everything you need to know about confusional arousals.

What Are Confusional Arousals?

Confusional arousal, also known as sleep drunkenness, is a condition that affects individuals during their sleep-wake transitions. During these episodes, people may experience disorientation and confusion upon waking up or falling asleep. If you’ve ever woken up feeling groggy or disoriented for a few minutes before becoming fully alert, you may have experienced confusional arousal.

These episodes can range from mild to severe and can last anywhere from a few seconds to several minutes. People experiencing confusional arousal may find it difficult to perform simple tasks such as dressing themselves or making breakfast. They may also become confused about where they are and what time it is. While most people with this condition only experience occasional episodes, those who suffer from more severe cases may experience them on a regular basis.

Risk Factors of Confusional Arousal

Confusional arousals and sleep drunkenness are two conditions that can severely affect an individual’s quality of life, productivity, and mental health. Although these conditions can affect individuals of all ages, certain subsets of adults are more likely to experience them. According to recent studies, people with a family history of confusional arousal, jobs requiring rotating or night shift work, and other sleep disorders like sleep apnea or periodic limb movements of sleep are at higher risk for these conditions.

In addition to the aforementioned factors, other risk factors include alcohol use near bedtime, excessive stress, and worry, bipolar disorder, or chronic depression. Sleep deprivation is yet another factor that exacerbates the occurrence and severity of confusional arousals and sleep drunkenness. These risk factors cause disturbances in the body’s natural circadian rhythm leading to alterations in one’s sleeping pattern which ultimately results in these conditions.

Causes of Confusional Arousals

Confusional arousals are a sleep disorder that can have detrimental effects on an individual’s daily life. Research suggests that there are several potential causes of this disorder, including recovery from sleep deprivation, alcohol consumption, sleep apnea, periodic limb movement disorder, psychotropic medication use, and drug abuse. Additionally, individuals may experience confusional arousal due to being forced to wake up suddenly.

According to studies, confusional arousals occur at the same rate among both men and women. However, rates of this condition are higher among children and adults under the age of 35. Experts estimate that as many as 17% of children may experience confusional arousal at some point in their lives. Meanwhile, about 3-4% of adults also report experiencing this sleep disorder.

Symptoms of Confusional Arousal

Confusional arousal is a sleep disorder that affects both adults and children. It is characterized by episodes of partial awakening from sleep, during which the person experiences confusion, disorientation, and sometimes hallucinations. These episodes usually occur during the first few hours of sleep but can also happen during naps or when waking up in the morning.

If you or someone you know is having confusional arousal, these are some of the symptoms to look out for:

  • Incoherent speech
  • Shouting
  • Blank stare upon waking up
  • When asked a question, the response could be delayed or inappropriate.
  • Sleepwalking
  • Confused as to where they are
  • Feeling confused or disoriented
  • Sudden arousal (and yet not fully awake)

The symptoms of Shouting and Sleepwalking are more severe than the others. These symptoms typically last for a few minutes, but they are quite rare.

Impacts of Confusional Arousals

Confusional arousals, like other NREM parasomnias, can have a significant impact on your daily life. These episodes of confusion and disorientation that occur during sleep can lead to daytime alertness issues, sleep deprivation, and excessive daytime sleepiness. If you experience frequent confusional arousals, it may also affect the quality of life for those sleeping with you.

While rare, there is also a possibility of unintentional harm to yourself or others nearby during confusional arousal episodes. This risk underscores the importance of understanding this condition and seeking help if necessary. Repeated experiences of confusional arousal can even trigger psychological distress.

Research shows that impairment during sleep inertia – even if less than 30 minutes – is equal to or worse than sleep loss. Poor work performance, memory retention problems, and reduced reaction times are just some examples of how these events negatively impact our daily lives.


Diagnosis of Confusional Arousal

If you’re experiencing confusional arousal or sleep drunkenness, it’s important to understand that these episodes can be difficult to detect. You may not even realize you’re having them unless someone else witnesses your behavior upon waking up. Common symptoms include confusion, aggression, and hostility during the transition from sleep to wakefulness. If this is happening regularly, it could indicate a serious underlying issue that requires medical attention.

To confirm whether you are indeed experiencing confusional arousals or sleep drunkenness, a visit with a sleep specialist is recommended. They will conduct a thorough medical history review and may ask you to keep a sleep diary over the course of several weeks. Additionally, an in-lab sleep study may be conducted to observe factors such as your breathing rate and limb movements while sleeping. This can provide valuable insights into the nature of your condition and help develop an effective treatment plan.

Treatment of Confusional Arousal

Confusional arousal is a type of sleep disorder that affects both children and adults. It is characterized by a state of confusion upon waking up from sleep, which can last from a few seconds to several minutes. Most cases of confusional arousal do not require treatment, as the symptoms usually begin early in childhood and reduce in frequency by age five. However, in some cases, the episodes can be frequent and disruptive to daily life.

In adults and children with underlying sleep or mental health disorders, treating the underlying condition may help alleviate the symptoms of confusional arousal. For instance, individuals diagnosed with anxiety or depression may benefit from therapy or medication to manage their symptoms. Similarly, those with obstructive sleep apnea may benefit from using a continuous positive airway pressure (CPAP) machine while sleeping to improve their quality of sleep.

One of the most crucial things parents and caregivers can do is to ensure that the person they are caring for practices good sleep hygiene.

Good sleep hygiene involves keeping to a regular sleep schedule, maintaining a sleep-friendly environment, and avoiding activities that interfere with quality rest. It is essential to create an environment free from hazards such as sharp-edged furniture, which could pose risks during episodes. Additionally, staying with the person until the episode subsides will help reassure them and prevent further confusion or accidents.

For cases where other interventions fail, doctors may recommend medications such as sedatives or antidepressants. However, these should only be used under medical supervision due to potential side effects.


Despite its prevalence, most cases do not require treatment as the symptoms usually subside over time. The condition is characterized by confusion and disorientation upon waking up in the middle of the night or early morning. According to research studies, most children outgrow their confusional arousal episodes by age five without any medical intervention.

There are several factors that can trigger confusional arousals, including underlying health problems such as fever or migraine, traveling across multiple time zones, abrupt sleep loss due to work schedule changes or lifestyle habits, as well as an irregular sleep-wake pattern due to shift work or other commitments. Although these episodes may seem harmless at first glance, they can disrupt normal sleeping patterns and lead to significant daytime fatigue and reduced cognitive function.


Confusional arousals are a type of sleep disorder that can cause confusion and disorientation upon waking up. It is more common in children but can also affect adults. Understanding the causes of this disorder and recognizing its symptoms is crucial in managing and treating it effectively. If you or your loved one’s experience similar symptoms, it’s highly recommended to seek medical attention and follow the prescribed treatment plan. With proper care, confusional arousal can be managed, allowing for better quality sleep and improved overall health and well-being.
