Sleep is a crucial aspect of human health, and its deprivation can have adverse effects on both mental and physical well-being. For children with epilepsy, the significance of sleep is twofold. Not only does sleep deprivation act as a trigger for seizures, but epilepsy can also cause sleep disorders, creating a vicious cycle that negatively impacts the child's overall health and quality of life.
Epilepsy is a brain disorder characterised by recurring seizures, which can be controlled through medication in most cases. However, the relationship between epilepsy and sleep is complex and bidirectional. Sleep deprivation can lower the seizure threshold, making children more susceptible to seizures, while epilepsy can disrupt sleep patterns and cause sleep-related disorders.
Furthermore, the occurrence of seizures during sleep can lead to unusual behaviours, such as waking up suddenly or making unusual noises. These behaviours can be indicators of nocturnal seizures, which are typically tonic-clonic seizures and are often linked to epilepsy.
Addressing sleep issues is essential for the overall management of epilepsy in children. By improving sleep quality and consolidating sleep patterns, the frequency and severity of seizures can be reduced, leading to better epilepsy control and an improved quality of life for both the child and their caregivers.
In conclusion, while it cannot be definitively stated that children with seizures need more sleep than regular kids, it is clear that sleep plays a pivotal role in managing epilepsy and its associated complications.

What You'll Learn
Sleep deprivation and epilepsy
Sleep is an essential factor in managing epilepsy. Sleep deprivation can increase a person's chances of having a seizure, regardless of the type. The brain's electrical patterns change as we become drowsy and enter sleep. Some people with epilepsy are sensitive to these changes and will have sleep-related epilepsy that triggers seizures.
Sleep problems are pervasive and persistent among children with epilepsy, and these issues may get worse with age. Children with epilepsy have a higher prevalence of excessive daytime sleepiness and sleep apnea symptoms than typically developing children. Sleep deprivation can also throw off a person's daily schedule, affecting the timing of their next dose of medication or causing them to accidentally skip it.
To improve sleep quality and consolidate sleep, which can ease controlling seizures, it is recommended to:
- Have fixed sleeping and awakening times every day, including weekends.
- Avoid naps if possible.
- Engage in regular exercise, particularly aerobic exercise.
- Avoid stimulating or strenuous exercise, especially in the evening.
- Avoid exhausting, exciting, annoying, or anxiety-provoking activities before bed.
- Avoid stimulating drinks like cola, coffee, tea, or other caffeinated beverages after noon.
- Avoid chocolate in the evening.
- Avoid drinking many liquids in the evening to prevent sleep disturbances due to the need to use the toilet.
- Use sedating anti-epileptics sparingly during the day, and use activating anti-epileptics when suitable.
Additionally, addressing sleep issues is crucial in improving epilepsy treatment. Sleep plays a vital role in a child's development and can impact their physical health, development, schoolwork, socialization, and safety.

Sleep disorders in children with epilepsy
Sleep is a vital factor in controlling seizures in children with epilepsy. Sleep deprivation can increase the chances of a seizure occurring, regardless of the type. Furthermore, sleep disorders are prevalent in children with epilepsy, and these issues may worsen with age.
Epilepsy and sleep are interconnected, with epilepsy disturbing sleep and sleep deprivation aggravating epilepsy. Sleep disorders are more common in children with epilepsy, and they often co-occur with the condition. The nature of seizures, the presence of coexisting sleep disorders, and even epilepsy medications can disrupt sleep in these children.
Effects of Sleep on Epilepsy
The electrical patterns in the brain change as one transitions from a drowsy state to sleep. These changes can trigger seizures in some individuals with epilepsy. Sleep deprivation can lower the seizure threshold, making it easier for seizures to occur.
Effects of Epilepsy on Sleep
Epilepsy can affect all sleep parameters, including nighttime difficulties and parent-child interactions. It can induce sleep fragmentation, parasomnias, and daytime drowsiness, resulting in memory dysfunction and impaired daytime functioning and quality of life.
Epilepsy and Parasomnia
Parasomnia is a category of sleep disorders characterised by abnormal behaviours, perceptions, movements, or dreams during sleep or while transitioning between sleep stages. Parasomnias are more frequent in children with frontal lobe epilepsy, suggesting a potential link between parasomnias and this type of epilepsy.
Epilepsy and Sleep-Related Hormones
Epilepsy can cause physiological hormonal changes in the neuroendocrine system, particularly in sex hormones. Melatonin, for example, is often used to treat sleep disorders, and its levels have been found to increase after seizures. However, some studies suggest that melatonin can also decrease the seizure threshold, potentially increasing seizure activity.
Sleep Hygiene in Children with Epilepsy
Adequate sleep is essential for overall health and seizure prevention in children with epilepsy. Implementing proper sleep hygiene practices, such as fixed sleeping and awakening times and regular exercise, can help improve sleep quality and seizure control.

The link between epilepsy and sleep hormones
Sleep and epilepsy are two well-recognised conditions that interact with each other in a complex, bidirectional way. Sleep deprivation can aggravate epilepsy due to decreased seizure thresholds, and epilepsy can, in turn, deteriorate sleep-related disorders. The secretion of sleep-related hormones can also be affected by the occurrence of seizures, and the supplementation of epileptic patients with these sleep-related hormones may have a beneficial role in controlling epilepsy.
The Effect of Sleep on Epilepsy
Almost two-thirds of seizures happen between 8:00 PM and 8:00 AM, with 20% of seizures occurring during sleep (nocturnal epilepsy). Sleep consists of repetitive cycles, each lasting about 90 minutes, advancing through non-rapid eye movement (NREM) stages to rapid eye movement (REM) sleep. NREM sleep can enhance interictal epileptiform discharges in both partial and generalised seizures, while REM sleep limits the spread of epileptic discharges outside the area that started the seizure activity. The seizure-activating role of NREM sleep has been attributed to increased neuronal synchronisation within thalamo-cortical projection neurons with robust activation of epileptic ictal and interictal activity. Most sleep-related seizures start during sleep stage II.
The Effect of Epilepsy on Sleep
Ineffective or inadequate sleep is common in epilepsy patients. Their sleep could be disturbed by the nature of their seizures, the presence of coexisting sleep disorders, and sometimes by seizure medications. The epilepsy may affect all sleep parameters, including nighttime difficulties and parent/child interaction during the night. It can also induce sleep fragmentation, parasomnias, and daytime drowsiness. This can result in memory dysfunction and considerable impairment of daytime functioning and quality of life.
Epilepsy and Sleep-Related Hormones
Many physiological hormonal changes in the neuroendocrine system occur in epileptic patients, especially in sex hormones. The mechanisms of these neuroendocrine changes are not yet fully elaborated. The hypothalamic-pituitary-adrenal axis function could be impaired acutely during the seizure or may be affected chronically in epileptic patients. Melatonin is a powerful chronobiotic secreted from the pineal gland, which helps maintain normal circadian rhythms and is used to treat sleep disorders. Patients with intractable epilepsy have low baseline melatonin levels that increase dramatically following seizures. Night-time melatonin intake has proven to be helpful in alleviating epileptic activity in children, especially myoclonic types and nocturnal epilepsies. However, it is unclear whether this alleviating effect was through improving the quality of sleep or through a more specific neuroprotective function.
Some studies have demonstrated an increase in certain hormones immediately after a seizure. The serum levels of prolactin and sex-related hormones (luteinising hormone and follicle-stimulating hormone) were found to increase in the postictal stage in epileptic patients with either generalised tonic-clonic or partial seizures. Serum prolactin showed transient increases following epileptic seizures, and these increases could be used to discriminate between true epileptic and psychogenic fits.

Sleep apnea and epilepsy
Sleep apnea is a sleep disorder characterised by interrupted breathing during sleep, which can affect the brain and body in ways that may make seizures more likely. It is associated with stroke, heart disease, hypertension, diabetes, obesity, and sudden death. Sleep apnea can also negatively impact performance at school or work.
Obstructive sleep apnea (OSA) is a type of sleep apnea that involves a narrowed airway during sleep. OSA is especially common in people who have persistent epilepsy and more frequent seizures. People with epilepsy are more likely to have OSA, and the most common symptoms of OSA include slowed or stopped breathing during sleep, frequent snoring that may involve sounds of choking or gasping, and difficulty staying awake during the day.
There is a bidirectional relationship between OSA and epilepsy. OSA can exacerbate epilepsy by causing sleep deprivation, hypoxemia, and disruption to the body's natural sleep-wake cycle. On the other hand, epilepsy can exacerbate OSA by disrupting sleep and weakening the muscles in the upper airway. Additionally, anti-epileptic drugs are known to worsen OSA.
The treatment of OSA in people with epilepsy has resulted in better control of epilepsy. Positive airway pressure (PAP) therapy, such as with a CPAP machine, can effectively treat OSA and may reduce epileptic seizures. However, more studies are needed to identify the optimal treatment plan for people with both OSA and epilepsy.

Sleep interventions for children with epilepsy
Sleep is a crucial factor in managing epilepsy in children. While epilepsy can disturb sleep, sleep deprivation can also provoke seizures. Therefore, it is important to address sleep issues in children with epilepsy to improve their overall quality of life.
- Address sleep disorders: Sleep disorders such as obstructive sleep apnea, circadian rhythm disorders, irregular sleep-wake patterns, and insomnia are more common in children with epilepsy. Treating these sleep disorders can help manage epilepsy and improve sleep quality.
- Maintain a healthy sleep schedule: Establishing a fixed sleeping and waking schedule, including weekends, can improve sleep hygiene and reduce sleep deprivation.
- Encourage physical activity: Regular exercise, particularly aerobic exercise, can improve sleep quality and epilepsy control. However, stimulating or strenuous exercise should be avoided close to bedtime.
- Create a calming bedtime routine: Avoiding exhausting, exciting, or anxiety-provoking activities before bed can help children feel more relaxed and ready for sleep. Quiet, relaxing activities and breathing techniques can be beneficial.
- Limit stimulating drinks and foods: Stimulating drinks like cola, coffee, tea, and other caffeinated beverages, as well as chocolate, should be avoided later in the day to prevent sleep disturbances.
- Monitor medication side effects: Certain anti-epileptic medications can affect sleep. For example, benzodiazepines and barbiturates can cause sleep disturbances, while phenytoin and carbamazepine may have less impact on sleep. Gabapentin has been shown to improve sleep quality.
- Consider alternative treatments: In some cases, alternative treatments such as the ketogenic diet may be considered to improve sleep quality and epilepsy management.
- Use early warning systems: Seizure detection systems, such as the NightWatch system, can help alert parents or caregivers to potential seizures, reducing the risk of medical complications and allowing for more restful nights.
- Optimise sleep hygiene: This includes avoiding naps, limiting screen time before bed, and creating a comfortable sleep environment.
- Address stress and mental health: Stress and mental health issues can impact sleep quality. Seeking support and maintaining mental wellbeing can help improve sleep and reduce seizure triggers.

Frequently asked questions
Sleep is a crucial factor in controlling seizures. Sleep deprivation can increase the chances of a seizure, regardless of its type. However, the relationship between sleep and seizures is complex and bidirectional. While adequate sleep helps prevent seizures, epilepsy can also disturb sleep.
Epilepsy is a common brain disorder affecting around 3.4 million Americans, including children. It involves recurring seizures resulting from increased electrical activity in the brain.
During a nocturnal seizure, a person may cry out, suddenly appear rigid, be difficult to wake after the seizure, or display confusion and unusual behaviours afterward. They may also wake up suddenly for no apparent reason. Some people with nocturnal seizures are unaware of having them and only experience symptoms like headaches or bruises upon waking.
Nocturnal seizures are usually linked to epilepsy, particularly frontal lobe epilepsy. Other potential causes include strokes, blood vessel malformations, and tumours. Risk factors include a family history of seizures, age over 40, sleep disorders, and a history of hospitalisation.
Treatment options include anti-seizure medication, avoiding triggers like sleep deprivation, a ketogenic diet, and a vagus nerve stimulator implant. Preventative measures to reduce injury risk during nocturnal seizures include using a low bed frame, placing a safety mat next to the bed, and using wall-mounted lamps.
