Simple partial (focal) seizures or 'auras'

A simple partial seizure can cause:

• a general strange feeling that's hard to describe
• a "rising" feeling in your tummy – like the sensation in your stomach when on a fairground ride
• a feeling that events have happened before (déjà vu)
• unusual smells or tastes
• tingling in your arms and legs
• an intense feeling of fear or joy
• stiffness or twitching in part of your body, such as an arm or hand

You remain awake and aware while this happens.

These seizures are sometimes known as "warnings" or "auras" because they can be a sign that another type of seizure is about to happen.

Complex partial (focal) seizures

During a complex partial seizure, you lose your sense of awareness and make random body movements, such as:

• smacking your lips
• rubbing your hands
• making random noises
• moving your arms around
• picking at clothes or fiddling with objects
• chewing or swallowing

You will not be able to respond to anyone else during the seizure and you will not have any memory of it.

Tonic-clonic seizures

A tonic-clonic seizure, previously known as a "grand mal", is what most people think of as a typical epileptic fit.

They happen in 2 stages – an initial "tonic" stage, shortly followed by a second "clonic" stage:

1. tonic stage – you lose consciousness, your body goes stiff, and you may fall to the floor
2. clonic stage – your limbs jerk about, you may lose control of your bladder or bowel, you may bite your tongue or the inside of your cheek, and you might have difficulty breathing

The seizure normally stops after a few minutes, but some last longer. Afterwards, you may have a headache or difficulty remembering what happened and feel tired or confused.

Absences

An absence seizure, which used to be called a "petit mal", is where you lose awareness of your surroundings for a short time. They mainly affect children, but can happen at any age.

During an absence seizure, a person may:

• stare blankly into space
• look like they're "daydreaming"
• flutter their eyes
• make slight jerking movements of their body or limbs

The seizures usually only last up to 15 seconds and you will not be able to remember them. They can happen several times a day.

Myoclonic seizures

A myoclonic seizure is where some or all of your body suddenly twitches or jerks, like you've had an electric shock. They often happen soon after waking up.

Myoclonic seizures usually only last a fraction of a second, but several can sometimes occur in a short space of time. You normally remain awake during them.

Clonic seizures

Clonic seizures cause the body to shake and jerk like a tonic-clonic seizure, but you do not go stiff at the start.

They typically last a few minutes and you might lose consciousness.

Tonic seizures

Tonic seizures cause all your muscles to suddenly become stiff, like the first stage of a tonic-clonic seizure.

This might mean you lose balance and fall over.

Atonic seizures

Atonic seizures cause all your muscles to suddenly relax, so you may fall to the ground.

They tend to be very brief and you'll usually be able to get up again straight away.

Status epilepticus

Status epilepticus is the name for any seizure that lasts a long time, or a series of seizures where the person does not regain consciousness in between.

It's a medical emergency and needs to be treated as soon as possible.

You can be trained to treat it if you look after someone with epilepsy. If you have not had any training, call 999 for an ambulance immediately if someone has a seizure that has not stopped after 5 minutes.
