seizure at night
Informed by recognized medical guidance
Overview
A seizure at night is a burst of abnormal electrical activity in the brain that happens while you are asleep. It can cause movements, unusual sensations, or loss of awareness, and you may not remember it in the morning.
Key facts
- About 1 in 3 people with epilepsy have seizures mainly during sleep.
- Nocturnal seizures can be mistaken for nightmares or sleepwalking.
- They often happen in the first few hours after falling asleep or just before waking.
Nocturnal seizures are fairly common among people with epilepsy, but they can also occur in people who do not have a diagnosis of epilepsy.
They can affect people of any age, but are more common in children and older adults. In children, they may be linked to certain types of epilepsy that start in childhood.
Symptoms
- A seizure that lasts longer than 5 minutes
- Repeated seizures without fully waking up in between
- Trouble breathing or turning blue during a seizure
- This is the first seizure you or your child has ever had
- ⚠You experience confusion, headache, or weakness that lasts more than 30 minutes after a seizure
- ⚠You injure yourself during the seizure, such as a cut or head bump
- ⚠You are pregnant and have a seizure
Common symptoms
- Waking up with a headache, sore muscles, or a bitten tongue or cheek
- Finding your bed wet or your pillow moved
- Feeling confused or very tired in the morning
- Not remembering your dreams or waking up feeling 'off'
Symptoms in children
- Bedwetting that was not a problem before
- Sleepwalking or acting confused during the night
- Having night terrors or crying out in sleep
Symptoms in older adults
- Morning confusion or memory problems
- Falls from bed or injuries during the night
- Feeling very sleepy during the day without a clear reason
Causes
Main causes
- Epilepsy – a brain condition that causes repeated seizures
- Fever (especially in young children) – called febrile seizures
- Head injury, brain infection (like meningitis), or stroke
- Sleep deprivation, alcohol withdrawal, or certain medicines
Risk factors
- Family history of epilepsy or seizures
- Lack of sleep or irregular sleep schedule
- Stress, fever, or flashing lights (in some people)
When to see a doctor
See a doctor urgently if:
- You or your child has a seizure for the first time
- A seizure happens without a known trigger, such as fever
- You are pregnant and have a seizure
Book a routine appointment if:
- You already know you have epilepsy but your seizures are happening more often or are different
- Your treatment does not seem to be working well
Diagnosis
A doctor – usually a neurologist (brain and nerve specialist) – will ask about what happened during the night, your sleep habits, and any other health conditions. They may also want to talk with family members who saw the seizure.
Tests that may be done
- EEG (electroencephalogram) – a recording of your brain's electrical activity, often done while you sleep
- Sleep study (polysomnography) – if they think the seizures are linked to a sleep disorder
- MRI (magnetic resonance imaging) of the brain – to look for structural causes
What to expect at your appointment
Diagnosing nocturnal seizures can take time because you may not remember them. The doctor may ask you to keep a sleep diary or record a video of your sleep. Tests are usually done as an outpatient and are painless.
Treatment
Treatment aims to stop or reduce seizures and improve sleep quality. The right plan depends on the cause and your overall health.
Self-care at home
- Stick to a regular sleep schedule – go to bed and wake up at the same time every day
- Avoid alcohol and limit caffeine, especially in the evening
- Keep a seizure diary to track possible triggers
Medical treatments
Doctors usually start with antiseizure medicines (also called anti-epileptic drugs). The choice of medicine depends on the type of seizure, your age, and other health factors. It may take a few tries to find the one that works best for you with the fewest side effects.
When is surgery considered?
If medicines do not control the seizures and doctors can find a specific spot in the brain where they start, surgery to remove that spot may be an option. This is only recommended after careful testing and discussion with a specialist team.
Living with this condition
Living with nocturnal seizures means taking steps to stay safe while you sleep. Tell family members or roommates what to do if you have a seizure. Consider using a bed alarm or placing a soft mattress on the floor if you fall out of bed.
Lifestyle tips
- Avoid sleep deprivation – it is one of the most common triggers
- Manage stress with relaxation techniques like deep breathing or meditation
- Wear a medical alert bracelet so that emergency helpers know about your seizures
Diet and exercise
A balanced diet and regular exercise can help overall brain health. Some people with epilepsy try a special diet (like the ketogenic diet) under medical supervision, but do not change your diet without talking to your doctor.
Mental health and emotional wellbeing
Having seizures at night can be frightening and may cause anxiety, depression, or stress about going to sleep. It is normal to feel worried. Talk to your doctor or a mental health professional – help is available.
Prevention
Not all nocturnal seizures can be prevented, but you can lower your risk by managing triggers. Taking your medicine exactly as prescribed, getting enough sleep, and avoiding alcohol are key steps.
Complications
If left untreated
- Injury during the seizure, such as falling out of bed or biting your tongue
- Status epilepticus – a prolonged seizure that is a medical emergency
- SUDEP (Sudden Unexpected Death in Epilepsy) – very rare but more likely if seizures are not controlled
Long-term outlook
With proper treatment, most people with nocturnal seizures can achieve good seizure control or stop having them altogether. It may take time to find the right approach, but staying in touch with your healthcare team gives you the best chance of a healthy, active life.
