Epilepsy living patient overview

Overview

Epilepsy is a brain condition that causes repeated seizures. A seizure is a sudden burst of electrical activity in the brain that can change how you feel, move, or act. Having one seizure does not mean you have epilepsy – doctors usually diagnose epilepsy after two or more unprovoked seizures.

Yes. Epilepsy is one of the most common neurological conditions in the world. It affects about 1 in 100 people globally.

Epilepsy can start at any age, but it is most often diagnosed in children and older adults. Both men and women are affected equally. It can happen to anyone, regardless of race or background.

Symptoms

Common symptoms

• Temporary confusion or staring into space
• Uncontrollable jerking movements of the arms and legs
• Loss of awareness or consciousness
• Strange feelings, smells, or tastes before a seizure (called an aura)
• Falling down suddenly without a clear reason

Symptoms in children

• Brief spells of staring (absence seizures)
• Sudden stiffening or jerking while awake
• Unusual drowsiness or confusion after a spell
• Learning difficulties or behavior changes that seem out of the blue

Symptoms in older adults

• Confusion that looks like memory loss
• Sudden falls without warning
• Unusual 'spacing out' during conversations
• Sensations like tingling, déjà vu, or odd smells before a seizure

Causes

Main causes

• In many people, the cause is unknown (idiopathic epilepsy).
• Brain injury from trauma, stroke, or infection (like meningitis)
• Abnormal brain structures present from birth
• Genetic changes that make the brain more prone to seizures

Risk factors

• Family history of epilepsy
• Head injury, especially with loss of consciousness
• Stroke or other brain blood vessel problems
• Brain infections such as meningitis or encephalitis
• Brain tumor (though less common)

When to see a doctor

See a doctor urgently if:

• After your first seizure, even if you feel fine
• Seizure with confusion that does not clear up quickly
• Seizure causing injury or change in breathing

Book a routine appointment if:

• If you have more than one seizure and have not yet been diagnosed
• If your current seizure pattern changes or gets worse
• If you have side effects from epilepsy medicines that bother you
• If you are planning a pregnancy and have epilepsy

Diagnosis

A doctor (usually a neurologist) will take a detailed history of your seizures, ask about any brain injuries or family history, and may order tests to understand what is happening in your brain.

Tests that may be done

• Electroencephalogram (EEG) – a painless test that records electrical activity in your brain
• Brain imaging (MRI or CT scan) to look for injuries or abnormalities
• Blood tests to check for other causes of seizures like infections or low blood sugar

What to expect at your appointment

The diagnosis process can take time because the doctor needs to rule out other conditions. You may be asked to keep a seizure diary, describing what happens before, during, and after each seizure. This helps your doctor find the right treatment.

Treatment

Treatment for epilepsy aims to stop or reduce the number of seizures with the fewest side effects. For most people, medicines work well. If medicines do not help, other options like surgery or nerve stimulation may be discussed.

Self-care at home

• Take your medicines exactly as prescribed – never stop suddenly without talking to your doctor
• Keep a seizure diary to track triggers and patterns
• Get enough sleep and manage stress
• Avoid known triggers such as flashing lights (if you have photosensitive epilepsy) or alcohol misuse

Medical treatments

Doctors prescribe antiseizure medicines (also called anti-epileptic drugs) to control the electrical activity in your brain. The choice depends on the type of seizure, your age, and other health conditions. It may take a few tries to find the best one. Never change or stop your medicine unless your doctor tells you to.

When is surgery considered?

When medicines do not control seizures, surgery to remove a small part of the brain that causes them may be an option. This is only possible if the seizure focus is in an area that can be safely removed. Other options include vagus nerve stimulation (VNS) or ketogenic diet, especially for children.

Living with this condition

Living with epilepsy means being aware of your triggers, taking your medicine, and planning ahead to stay safe. Most people can work, drive (if seizure-free for a required period by local laws), and enjoy hobbies. Wearing a medical alert bracelet can be helpful in case of a seizure.

Lifestyle tips

• Get regular sleep – lack of sleep is a common trigger
• Limit alcohol and avoid recreational drugs
• Manage stress with relaxation techniques like deep breathing or meditation
• Tell close friends, family, and coworkers about your condition and what to do if you have a seizure

Diet and exercise

Regular exercise is safe and beneficial for most people with epilepsy. Do not exercise alone if your seizures are uncontrolled. The ketogenic diet (high fat, very low carb) is sometimes used in children whose seizures do not respond to medicine, but it should only be started under medical supervision.

Mental health and emotional wellbeing

Living with epilepsy can cause anxiety about when the next seizure might happen, or worry about how others see you. Depression and low mood are more common in people with epilepsy than in the general population. It is important to talk to your doctor or a counselor if you feel overwhelmed.

Prevention

Most cases of epilepsy cannot be prevented. However, you can lower your risk by preventing head injuries (wear seatbelts and helmets), managing high blood pressure and diabetes to reduce stroke risk, and treating brain infections promptly.

Complications

If left untreated

• Repeated seizures can affect memory and learning
• Risk of injury during a seizure (falls, burns, drowning)
• Sudden unexpected death in epilepsy (SUDEP) – though rare, it is more common in people whose seizures are not controlled

Long-term outlook

With proper treatment, about 70% of people with epilepsy become seizure-free. Many people live full, active lives including studying, working, raising families, and traveling. Epilepsy does not define you – it is just one part of your health story.
