Absence seizures are often difficult to detect - they can look like the casualty is simply spacing out, which is why it is important to take action quickly once it is identified as an absence seizure.
The main difference you would be able to see is that in an absence seizure, the person cannot be brought out of the seizure and will not be able to respond to you.
Stretch!
In schools, absence seizures can be misdiagnosed as daydreaming, inattention, or even behavioural issues. This can delay treatment, and cause social or academic consequences.
Signs:
Sudden "switch off"
Blank, fixed stare
Small twitching
Repetitive movements
What to do:
Gently guide the casualty to sit down in a quiet, safe space - especially if they are having clusters* of absence seizures
Remove obstacles around the casualty
Time the seizure discreetly - it should last from 5 to 20 seconds
Stay with the casualty until fully recovered.
When they come to, explain to them anything they have missed and keep them calm.
Timing the seizure can help you know when it's serious enough to call 999.
Stretch!
Absence seizures can be triggered by hyperventilation* or flashing lights, but most are not caused by triggers at all.
Summary:
Absence seizures are short episodes where someone looks like they're "zoning out" but actually can't respond to anything around them. Don't panic - just get them safe, stay calm, and let an adult know.
Glossary:
Cluster: when someone keeps having lots of absence seizures close together in a short amount of time.
Hyperventilation: when someone starts breathing really fast, usually because they're scared or panicking about something.
