Understanding Epilepsy
A comprehensive guide to epilepsy, seizure types, triggers, treatment options, and living well with the condition.
What Is Epilepsy?
Epilepsy is a neurological condition that affects the brain and causes repeated seizures. It is one of the most common neurological conditions in the world, affecting around 1 in 100 people in the UK.
A seizure happens when there is a sudden burst of electrical activity in the brain, which temporarily disrupts the way brain cells communicate with each other.
Epilepsy can start at any age, though it most commonly begins in childhood or after the age of 60. It affects people of all backgrounds and walks of life.
Having epilepsy does not define who you are. Many people with epilepsy live full, active lives with the right support and treatment.
Types of Seizures
Focal seizures start in one area of the brain. You may remain aware during a focal seizure (focal aware) or your awareness may be affected (focal impaired awareness). Symptoms can include unusual sensations, jerking movements, or repetitive actions like lip-smacking.
Generalised seizures affect both sides of the brain from the start. These include tonic-clonic seizures (previously called grand mal), where the body stiffens and jerks, and absence seizures, where a person briefly loses awareness and may appear to stare blankly.
Tonic seizures cause the muscles to suddenly stiffen, which may cause a person to fall. Atonic seizures (drop attacks) cause a sudden loss of muscle tone, also leading to falls.
Myoclonic seizures cause brief, shock-like jerks of a muscle or group of muscles. They often happen shortly after waking up.
Not all seizures involve convulsions. Some seizures are very subtle and may be mistaken for daydreaming or inattention, especially in children.
Common Triggers
Lack of sleep is one of the most common seizure triggers. Maintaining a regular sleep schedule is important for seizure management.
Stress and anxiety can increase seizure frequency. Finding healthy ways to manage stress, such as breathing exercises and mindfulness, can be helpful.
Missed medication is a significant trigger. Taking anti-epileptic drugs (AEDs) at the same time every day is crucial.
Alcohol and recreational drugs can lower the seizure threshold and interact with medication. It's important to discuss alcohol use with your doctor.
Flashing or flickering lights (photosensitive epilepsy) affect about 3% of people with epilepsy. This can include strobe lights, sunlight through trees, or certain screen content.
Illness, fever, and hormonal changes (particularly in women during menstruation) can also affect seizure control.
Keeping a seizure diary can help you and your doctor identify your personal triggers and patterns.
Treatment Options
Anti-epileptic drugs (AEDs) are the main treatment for epilepsy. Around 70% of people with epilepsy can become seizure-free with the right medication.
Finding the right medication and dose may take time. Your neurologist will work with you to find the best option with the fewest side effects.
Surgery may be an option if seizures are not controlled by medication and originate from a specific area of the brain that can be safely removed.
Vagus nerve stimulation (VNS) involves a small device implanted under the skin that sends electrical impulses to the brain via the vagus nerve.
Ketogenic diet is a high-fat, low-carbohydrate diet that can help reduce seizures in some people, particularly children. It should only be followed under medical supervision.
Never stop or change your medication without consulting your doctor, as this can be dangerous and lead to increased seizures.
Seizure First Aid
During a tonic-clonic seizure: Stay calm. Protect the person from injury by moving harmful objects away. Cushion their head. Time the seizure. Do NOT restrain them or put anything in their mouth.
After the seizure: Gently place the person on their side in the recovery position. Stay with them and speak calmly until they have fully recovered. They may be confused or sleepy afterwards.
Call 999 if: The seizure lasts longer than 5 minutes, the person does not regain consciousness, they are injured, it is their first seizure, or seizures happen one after another.
During a focal seizure: Guide the person away from danger. Speak calmly and reassuringly. Do not restrain them. Stay with them until they have fully recovered.
Learning seizure first aid can save lives. Encourage family, friends, and colleagues to learn what to do.
Living Well with Epilepsy
Driving: In the UK, you must be seizure-free for 12 months (or have only had seizures during sleep for 3 years) before you can drive. You must inform the DVLA of your diagnosis.
Work: Most people with epilepsy can work. Employers have a legal duty to make reasonable adjustments under the Equality Act 2010. Epilepsy Action offers advice on employment rights.
Education: Schools and universities should make reasonable adjustments to support students with epilepsy, including exam arrangements and first aid plans.
Relationships and social life: Be open with people you trust about your epilepsy. This helps them support you and know what to do if you have a seizure.
Mental health: Anxiety and depression are more common in people with epilepsy. It's important to seek help for your mental health as well as your epilepsy.
Exercise and hobbies: Most sports and activities are safe with sensible precautions. Swimming should be supervised, and activities at height may need extra safety measures.
Epilepsy and Mental Health
Living with epilepsy can have a significant impact on your mental health. The unpredictability of seizures can cause anxiety, and the condition can affect self-esteem and confidence.
Depression affects around 1 in 3 people with epilepsy — a much higher rate than the general population. It can be caused by the condition itself, medication side effects, or the emotional impact of living with epilepsy.
Anxiety is also very common, particularly fear of having seizures in public or worrying about triggers. This can lead to avoiding social situations and isolation.
Some anti-epileptic medications can affect mood. If you notice changes in how you feel, speak to your doctor — adjusting your medication may help.
Talking therapies like CBT (cognitive behavioural therapy) can be very effective for managing the emotional challenges of epilepsy.
You are not alone. Support groups and peer communities can help you connect with others who truly understand what you're going through.
