What is Epilepsy?

Epilepsy is a general term for seizures (uncontrollable shaking and jerking) that start in the brain. Seizures are bursts of electrical activity in the brain that temporarily affect how it works and they can cause a wide range of symptoms. Epilepsy is one of the most common serious neurological conditions in the world and it affects around 600,000 people in the UK.

Epilepsy can start at any age and there are many different types. Some types of epilepsy last for a limited time and the person eventually stops having seizures. But for many people epilepsy is a lifelong condition.



Symptoms of epilepsy

Seizures can affect people in different ways, depending on which part of the brain is involved. Possible symptoms include;

· Fits (uncontrollable jerking and shaking)

· Losing awareness

· Becoming stiff

· Strange sensations, such as a “rising” feeling in the tummy, unusual smells or tastes, and a tingling feeling in your arms or legs

· Collapsing

· Passing out


Causes of epilepsy

In over half of all people with epilepsy, there is no definitive cause. It is thought that our genes play a role in affecting how the brain works, as around 1 in 3 people with epilepsy have a family member with the condition. Occasionally, epilepsy can be caused by damage to the brain, for example from a stroke, brain tumour, severe head injury, drug or alcohol misuse, a brain infection and a lack of oxygen during birth.


Seizure triggers

Some things make seizures more likely for people with epilepsy. These “triggers” do not cause epilepsy itself, but they are things that make it more likely that you will have a seizure. Note that not all people with epilepsy have seizure triggers, and triggers can vary from person to person. Some of the common triggers may include;

· Not taking epilepsy medicine as prescribed

· Feeling tired and not sleeping well

· Stress

· Alcohol and recreational drugs

· Flashing or flickering lights

· Monthly periods

· Missing meals

· Having an illness which causes a high temperature


Diagnosis

A diagnosis is often carried out if you have had two or more seizures. It can be difficult to diagnose epilepsy as there is no single test for it and there are several different types. Your consultant will ask you to describe what happened during your previous seizures and find out if anything in particular triggered it. They will also ask you about your medical history and if anyone in your family has epilepsy. They may recommend certain diagnostic tests such as an electroencephalogram (EEG), to assess the electrical activity in your brain.


Treatment

Your neurologist will discuss your treatment options with you which may result in fewer seizures or stop having seizures completely. The main treatment offered is medicine called anti-epileptic drugs. In other cases, your neurologist may recommend surgery or a minimally invasive treatment which removes the brain tissue mutations that causes seizures. There is also a special diet called the ketogenic diet which can help to control symptoms, you will need to be referred to a Specialist Dietitian for this.
