Doctors do not know what causes this type of epilepsy, but it may be genetic. Not all nighttime seizures in children mean the child has epilepsy. Febrile seizures are usually harmless, and they typically resolve once the fever subsides. However, it is essential to see a doctor to rule out other causes, such as a brain injury or infection.
Nocturnal seizures are potentially dangerous and increase the risk of dying from epilepsy. Having a seizure while sleeping can also make a person prone to injuries.
People who experience nighttime seizures are more likely to suffer low blood oxygen during and after the seizure. They are also more likely to continue to experience unusual brain activity after the seizure. While this can be frightening, epilepsy is usually treatable.
The right treatment depends on the type of seizure a person has, the cause, and other health factors. Possible treatments include:. Tracking symptoms and triggers can help with identifying any patterns in the symptoms and whether the treatment plan is working. People who have nocturnal seizures may also wish to take measures to prevent injuries.
These can include:. Nocturnal seizures are potentially dangerous. For people with no previous history of seizures, they may be the first sign of epilepsy.
No matter how many nighttime seizures a person has or what medication they take, it is vital to see a doctor for any symptoms of nighttime seizures promptly. Controlling nighttime seizures can significantly reduce the risk of epilepsy complications. A full diagnosis can also rule out other causes of troubling symptoms at night.

By Danielle Pacheco October 8, By Danielle Pacheco October 1, By Jay Summer October 1, By Jay Summer September 30, Having a good night's sleep helps our brains to recover from the day's events, so that we can function well the next day.
For some people with epilepsy a lack of sleep can make seizures more likely to happen, for others having seizures at night can make them feel tired during the day.
The links between epilepsy and sleep are very complex. During sleep the brain is active, processing information to help us learn. Brain activity changes during the different stages of sleep. Sleep happens in an alternating pattern, and is divided into two different, alternating categories of sleep type.
Scientists believe that NREM sleep is important for strengthening connections between our brain cells and stabilising long-term memories. Deep sleep also helps the brain to recover from the day's events so that it can function well the next day.
The next stage of deep sleep is when most dreaming occurs. During REM sleep the brain tries to organise the information we have received throughout the day. The purpose of REM sleep and dreaming is unclear. However some theories suggest it may be important for making sense of our thoughts, ideas and experiences, and the emotions and memories attached to them.
A lack of sleep can affect our memories and judgement. It can also affect our mood and how well our immune system works. Some people have specific triggers for their seizures, for example a lack of sleep. In some types of epilepsy seizures can happen as someone is waking up and within the next few hours. For some people the effects of having a seizure can upset their sleep pattern for several days afterwards. As with all medications, anti-epileptic drugs AEDs can cause side effects for some people.
AEDs may have different effects on sleep, and this can vary from person to person, depending on the dose. Some AEDs are classed as sedatives and can cause tiredness. Some can cause insomnia or disrupted sleep. However some AEDs can help to improve the quality of sleep by increasing the length of deep sleep. Frontal lobe epilepsy is a type of epilepsy where seizures can commonly happen during periods of NREM sleep as well as when awake.
