Myoclonic seizures are quick, sudden, and often misunderstood. They can look like clumsiness or twitching but they’re actually brief bursts of electrical activity in the brain.
We asked young people and families to describe what a myoclonic seizure feels like. Their words are honest, powerful, and full of insight. Whether you’re living with epilepsy, supporting someone who is, or just want to understand better - this is for you.
What is a Myoclonic Seizure?
‘Myo’ means muscle and ‘clonic’ means jerk. Myoclonic seizures cause sudden, shock-like muscle contractions - usually in the arms, legs, or body.
Here’s what you might see:
- Sudden jerks or twitches.
- Dropping objects or falling.
- Brief loss of awareness (sometimes).
- Movements that look clumsy or random.
- Often happen just after waking or when tired.
They’re usually very short - but they can be intense, painful, and disruptive.

How can you help someone having a myoclonic seizure
You told us what really helps when you're having a seizure, and we listened. This guidance is shaped by a powerful mix of lived experience and clinically informed expert advice, coming together to help others know what to do.
Even though they only last a few seconds, a myoclonic seizure can be scary and confusing for both the person experiencing it and the person witnessing it. But you can help.
To help someone who is having a myoclonic seizure, follow these steps:
- Stay with them and make sure they’re safe.
- Move any hazards, like furniture, out of the way.
- Don’t move them unless it’s absolutely necessary, for example, if they are close to a hazard that cannot be moved, like an open fire, roads or open water.
- Be calm and reassure them, even if you think they can't hear you. This isn’t always easy, but it’s very important, especially when the person is recovering from the seizure and looking to you for reassurance.
- Make sure they’re okay and haven’t hurt themself.
- Don’t try and restrain them.
- Don’t let people film them on their phones.
- Please don't put anything in their mouth.
- Listen to how they want to be supported.
- How they feel after the seizure can be different each time.
- They might feel tired, confused and upset. Or they might feel okay.
Call an ambulance if they’ve seriously injured themself, or if they have lots of seizures in a short space of time.
