Here's All You Need To Know About Exploding Head Syndrome

Sleep is one of the most necessary lifestyle activities our body requires. It is one of those aspects that can even make or break a person's mental and physical well-being. Not getting enough sleep on a regular basis can be detrimental to one's health. This is when a sleep disorder known as exploding head syndrome comes into existence.

What is exploding head syndrome?

Exploding Head Syndrome (EHS) is a rare and relatively poorly understood sleep disorder. Despite its dramatic-sounding name, EHS is not associated with any physical harm or actual explosions. Instead, it's characterised by a specific type of auditory hallucination or sleep-related sensory experience. A person with this disorder often hears loud noises while going to sleep or when they wake up in the middle.

These sensations are often described as resembling explosions, gunshots, fireworks, door slams, or thunderclaps. Other than the loud noises, there can also be light flashes and muscle jerks, which aren't painful by nature.

EHS usually occurs during the transition between wakefulness and sleep, either as the person is drifting off to sleep (hypnagogic) or waking up from sleep (hypnopompic). It can happen at any age but is more common in older adults. The episodes of EHS can vary in frequency, ranging from occasional occurrences to multiple episodes in a single night. They may happen repeatedly over several nights and then disappear for weeks or months. Each episode of EHS is usually brief, lasting only a few seconds. Despite the intensity of the experience, it is generally not associated with pain.

What are the causes leading to exploding head syndrome?

There are several causes that lead to exploding head syndrome. Some of these causes are as follows:

Due to disruptions in sleep

One prominent theory suggests that EHS may be related to disruptions in the brain's sleep-wake cycle. During the transition from wakefulness to sleep or vice versa, the brain's sensory processing may become temporarily altered, leading to the perception of loud noises or sensations. A study published in the journal "Sleep Medicine" in 2015 examined the sleep patterns of individuals with EHS and found that they tended to have more irregular sleep schedules and higher rates of insomnia compared to the control group. This suggests that sleep disturbances may be a contributing factor.

Due to stress and anxiety

Stress and anxiety have been proposed as potential triggers for EHS episodes. Some research has indicated that individuals who experience high levels of stress or anxiety may be more prone to EHS. A study published in the "Journal of Sleep Research" in 2017 explored the relationship between EHS and psychological factors. The study found that participants with EHS reported higher levels of anxiety and stress compared to those without EHS.

Due to neurological factors

There is speculation that EHS may be linked to abnormalities in the brain's auditory processing centres. Some researchers believe that an abnormal firing of neurons in these areas could lead to the perception of loud noises during sleep transitions. While there isn't a specific study that conclusively demonstrates this connection, ongoing neuroimaging research may provide more insights into the neurological aspects of EHS.

Due to medication and withdrawal

Certain medications, such as antidepressants or benzodiazepines, have been reported to trigger EHS episodes or worsen existing symptoms in some individuals. Additionally, discontinuing certain medications can lead to withdrawal-related sleep disturbances, potentially including EHS-like experiences. A study published in "Psychosomatics" in 2012 reported a case of EHS associated with antidepressant withdrawal. However, more research is needed to establish a definitive link between medications and EHS.

Due to genetic factors

There is limited evidence to suggest that EHS may have a genetic component, as some cases appear to run in families. However, the genetic factors contributing to EHS remain largely unexplored, and more research is needed to confirm this. In summary, while there are several theories about the potential causes of Exploding Head Syndrome, no single cause has been definitively identified. EHS is likely a multifactorial condition influenced by a combination of sleep disturbances, psychological factors, and possibly neurological factors. Further research is necessary to better understand the underlying mechanisms and develop more effective treatments for individuals who experience EHS. If you or someone you know is experiencing EHS, consulting with a healthcare professional is advisable for proper evaluation and management.

What is the treatment?

EHS is typically diagnosed based on a person's description of their symptoms and a medical evaluation to rule out other potential causes of sleep disturbances or hallucinations. Polysomnography (sleep study) and other tests may be performed if necessary.

In most cases, EHS does not require specific treatment. However, if the episodes are causing significant distress or sleep disruption, healthcare providers may recommend addressing any underlying sleep problems, reducing stress, and establishing healthy sleep habits. In rare cases where EHS is severe and debilitating, medication may be considered.

EHS is generally harmless. However, if this causes prolonged distress, then one must consult a doctor.
