seizure with fatigue

Overview

Seizures are sudden bursts of electrical activity in the brain. Fatigue is an extreme tiredness that doesn’t go away with rest. For some people, seizures can cause fatigue. And for others, feeling very tired can sometimes trigger a seizure. This article explains how these two conditions are connected and what you can do about it.

Yes, it is common for people who have seizures to also experience fatigue. Many people with epilepsy report that tiredness is a major issue in their daily lives.

Anyone who has seizures can be affected by fatigue. It is especially common in people with epilepsy, but can also happen after a single seizure from other causes.

Symptoms

Common symptoms

• Extreme tiredness after a seizure
• Difficulty thinking or concentrating after a seizure
• Headache or muscle aches after a seizure
• Feeling sleepy or 'foggy' for hours or days

Symptoms in children

• Acting more fussy or irritable after a seizure
• Falling asleep soon after a seizure
• Complaining of being very tired, even after a good night’s sleep

Symptoms in older adults

• Longer recovery time after a seizure
• Increased weakness or confusion
• Higher risk of falls due to fatigue

Causes

Main causes

• Seizures themselves can cause fatigue because the brain and body use a lot of energy during a seizure
• Sleep disruption from nighttime seizures can lead to daytime fatigue
• Some medicines for seizures can cause drowsiness or tiredness as a side effect
• Fatigue can also be a trigger for seizures – lack of sleep is a common trigger

Risk factors

• Having epilepsy
• Taking seizure medications that cause drowsiness
• Poor sleep habits or sleep disorders
• Stress and anxiety
• Alcohol or drug use

When to see a doctor

See a doctor urgently if:

• If you have a seizure for the first time
• If your seizures become more frequent or severe
• If you feel very tired and it is affecting your safety, such as while driving

Book a routine appointment if:

• If you often feel extremely tired after seizures and it lasts for a long time
• If fatigue is affecting your work, school, or daily life
• If you think your seizure medication might be causing too much drowsiness

Diagnosis

Your doctor will ask about your seizures and your fatigue. They will want to know how often you have seizures, how long the fatigue lasts, and what makes it better or worse.

Tests that may be done

• Electroencephalogram (EEG) – a test that records the brain’s electrical activity
• Blood tests to check for other causes of fatigue, like anaemia or thyroid problems
• Sleep study – if your doctor thinks a sleep disorder might be triggering seizures

What to expect at your appointment

Your doctor may ask you to keep a diary of your seizures and your fatigue. This can help find patterns. Treatment will focus on controlling seizures and managing fatigue.

Treatment

Treatment for seizures and fatigue aims to control seizures as much as possible and to address the causes of fatigue. This may involve adjusting seizure medications, improving sleep, and making lifestyle changes.

Self-care at home

• Get enough sleep every night – aim for 7-9 hours
• Stick to a regular sleep schedule, even on weekends
• Avoid alcohol and caffeine, especially close to bedtime
• Manage stress through relaxation techniques like deep breathing or meditation
• Keep a seizure and fatigue diary to share with your doctor

Medical treatments

Your doctor may adjust the dose or type of your seizure medication to find a balance between controlling seizures and reducing side effects like drowsiness. They may also prescribe medications to help with sleep or treat other health problems that cause fatigue, but only after a full assessment. Never change medication without consulting your doctor.

When is surgery considered?

In rare cases, if seizures are caused by a specific area of the brain that can be safely removed, surgery might be an option. This is not a treatment for fatigue itself but may help control seizures, which could improve fatigue.

Living with this condition

Living with seizures and fatigue can be challenging, but many people manage well with good routines. Plan your day to include rest breaks. Avoid activities that could be dangerous if you become drowsy suddenly.

Lifestyle tips

• Build rest into your daily schedule
• Ask for help from family or friends when needed
• Avoid driving if you are very tired or if your seizures are not well controlled – check with your local driving authority
• Wear a medical alert ID that says you have seizures

Diet and exercise

A balanced diet can help you feel more energetic. Try to eat regular meals and drink enough water. Gentle exercise, like walking or yoga, can boost your energy and improve sleep. But avoid overexertion, which can trigger seizures in some people.

Mental health and emotional wellbeing

Living with a long-term condition like seizures can be stressful and may lead to anxiety or depression. Fatigue can make this worse. Talk to your doctor if you feel down or worried. Counseling or support groups can help.

Prevention

You cannot always prevent seizures, but you may be able to reduce their frequency by managing triggers like lack of sleep, stress, and alcohol. Managing fatigue may also help prevent some seizures.

Complications

If left untreated

• Repeated seizures that are not controlled can affect memory and learning
• Fatigue can increase the risk of accidents and falls
• Poor seizure control can lead to injury or status epilepticus
• Chronic fatigue can affect relationships and work

Long-term outlook

With proper treatment and lifestyle management, many people with seizures and fatigue can lead full and active lives. It may take time to find the right treatment plan, but most people see improvement. Work closely with your doctor and do not lose hope.
