Nocturnal seizures, or sleep seizures, occur while a person is sleeping and are often associated with epilepsy. They can happen during any stage of sleep and can cause unusual nighttime behaviour such as jerking and shaking of the body. Sleep seizures can be dangerous and increase the risk of sudden death in epilepsy (SUDEP). They can also lead to injuries and affect sleep for the rest of the night. Sleep deprivation is common among people with epilepsy, and lack of sleep can also trigger seizures. Diagnosing nocturnal seizures can be challenging as they occur at night and may go unnoticed, but treatment can help reduce the risk of complications.

- Epilepsy is the most common cause of seizures, but other conditions can also cause nocturnal seizures
Nocturnal seizures are often unnoticed, but a loved one may notice abnormal noises or jerking motions
Nocturnal seizures are often unnoticed because the patient is asleep when they happen. However, they can sometimes be identified by a loved one who may notice abnormal noises or jerking motions. Other signs that may suggest a person is experiencing nocturnal seizures include unusual sleepiness, headaches, and signs of drooling, vomiting, or bedwetting.
Nocturnal seizures can be dangerous and increase the risk of dying from epilepsy. They can also cause sleep disruption, leading to fatigue, poor quality sleep, and daytime sleepiness. This can be particularly detrimental to children with epilepsy, as sleep plays a crucial role in brain development.
If you suspect that you or a loved one is experiencing nocturnal seizures, it is important to seek medical help. A doctor may recommend a sleep study or a sleep EEG to monitor brain activity during sleep. Treatment options can include anti-seizure medications, lifestyle changes, or other therapies to manage symptoms.
Additionally, seizure alarms or monitors can be used as part of a risk management plan, although they cannot guarantee safety during a seizure. These alarms can detect movements associated with certain types of seizures, such as tonic-clonic seizures. Seeking medical advice is crucial to determine the best course of action and reduce the risk of complications.

Sleep studies can help rule out other issues, such as sleep apnea
Nocturnal seizures occur while a person is falling asleep, sleeping, or waking up. They can cause unusual nighttime behaviour, such as waking for no reason, urinating while sleeping, and jerking and shaking of the body. The exact reason why seizures happen during sleep is unknown. However, excessive hypersynchronous activity in the brain during sleep may contribute. Nocturnal seizures are potentially dangerous and can increase the risk of dying from epilepsy.
If you think you might be having seizures in your sleep, it is important to talk to your healthcare team. Your doctor may recommend a sleep study to help diagnose your condition. Sleep studies are common diagnostic tests that involve monitoring and recording your body systems while you sleep. They can help rule out other issues, such as sleep apnea, narcolepsy, restless leg syndrome, and other sleep-related issues. Sleep apnea tests, also known as polysomnograms (PSGs), can be done in a sleep disorder centre or at home. They electronically record specific physical activities while you sleep, such as brain wave activity, eye movement, and heart electrical activity.
If you are diagnosed with sleep seizures, a specialist can discuss possible treatment options, including changes to epilepsy medications, lifestyle changes, or other therapies to help manage your symptoms. Additionally, if you are experiencing disturbed sleep due to sleep seizures, your doctor can refer you to an epilepsy specialist. They may recommend a sleep EEG to record your brain activity while you sleep or suggest a seizure alarm or monitor as part of a risk management plan.
It is important to note that not all people with nocturnal seizures are aware that they are experiencing them. Sometimes, the only symptom is a headache or a bruise upon waking. If you or someone you know experiences nocturnal seizures, seek medical help immediately. Treatment can greatly reduce the risk of complications.

Nocturnal seizures can cause unusual nighttime behaviour, such as sleepwalking or night terrors
Nocturnal seizures can be difficult to distinguish from parasomnias such as sleepwalking or night terrors. People who live alone may wake up tired and not know that they have had a seizure. Nocturnal seizures can also cause unusual nighttime behaviour such as waking for no reason, urinating while sleeping, and jerking and shaking of the body. They can be dangerous and increase the risk of dying from epilepsy. They can also make a person prone to injuries, such as biting their tongue or losing control of their bladder or bowels.
If you think you might be having seizures in your sleep, it is important to talk to a healthcare professional. They may recommend further tests, such as a sleep electroencephalogram (EEG) to record your brain activity while you are asleep, or a sleep study to rule out other issues such as sleep apnea. If you are diagnosed with sleep seizures, a specialist can discuss possible treatment options, including changes to epilepsy medications, lifestyle changes, or other therapies to help manage your symptoms.
To reduce the risk of sudden unexpected death in epilepsy (SUDEP), it is important to take measures to prevent injuries during nocturnal seizures. This may include having nighttime supervision or using a seizure alarm or monitor. Alarms can be useful as part of a risk management plan, especially if there is someone nearby who can be alerted.

A seizure during sleep may affect sleep for the rest of the night, causing lighter sleep and more frequent awakenings
Nocturnal seizures, or seizures during sleep, are often unnoticed as the patient is asleep when they happen. However, they can cause unusual nighttime behaviour, such as jerking and shaking of the body, bedwetting, or sleepwalking. They can also cause the person to wake up multiple times during the night, disrupting their sleep.
Seizures during sleep can affect sleep for the rest of the night, causing lighter sleep and more frequent awakenings. This can lead to fatigue, poor quality sleep, and daytime sleepiness. The impact of disrupted sleep might be greater in children with epilepsy, as sleep is important for the brain to develop its processes and structure, which are crucial for a child's learning and development.
If you think you might be having seizures in your sleep, it is important to consult a doctor or epilepsy specialist. They may recommend a sleep study or a sleep EEG to record your brain activity while you are asleep. Treatment options may include changes to epilepsy medications, lifestyle changes, or other therapies to help manage symptoms.
Additionally, people with epilepsy should be aware of their risk of sudden unexpected death in epilepsy (SUDEP). Sleeping alone and having certain types of seizures, such as tonic-clonic seizures, can increase this risk. Risk reduction strategies may include having nighttime supervision or using a seizure alarm or monitor.

Epilepsy is the most common cause of seizures, but other conditions can also cause nocturnal seizures
Nocturnal seizures occur when a person is asleep and can cause unusual nighttime behaviour, such as waking for no reason, bedwetting, tongue biting, jerking and shaking of the body. They are most commonly associated with epilepsy, which is an umbrella term for various seizure disorders. Doctors diagnose epilepsy when a person has two or more unprovoked seizures, at least 24 hours apart, that are not caused by another medical condition.
However, it is important to note that not all nocturnal seizures are caused by epilepsy. Certain types of epilepsy are more likely to cause nocturnal seizures, such as benign rolandic epilepsy, which is the most common form of childhood epilepsy and usually disappears in adulthood. Juvenile myoclonic epilepsy, also known as Janz syndrome, typically begins in adolescence, and while seizures may be short at first, they can progress in severity.
In some cases, nocturnal seizures may be the result of other underlying conditions or factors. For example, sleep apnea, scar tissue, tumours, or structural problems in the brain could be potential causes. Distinguishing nocturnal seizures from other sleep behaviours, such as sleepwalking or night terrors, can be challenging, especially in children.
If you suspect you or someone you know is experiencing nocturnal seizures, it is crucial to seek medical advice. A doctor may recommend a sleep study or an electroencephalogram (EEG) to monitor brain activity during sleep and help diagnose the condition accurately. Treatment options can then be discussed with a specialist, which may include anti-seizure medications, lifestyle changes, or other therapies.
