For people seeing an epilepsy attack for the first time, it may come as a surprise that a person can make uncontrollable movements so hard. Seizures during an epilepsy attack are electrical impulses sent to the muscles by the brain, where electrical discharges continue.
Nothing that you put in person's mouth can prevent biting their tongue. It can even be harmful because the sick person can brake their teeth!
Even if the limbs are stuck in external elements such as: furniture, handrails, tracks. Compression other than the person's muscles can break bones.
Explain to people that this is an epilepsy attack.
Do not stop the person's head from twitching. Try to protect their head e.g. by putting it on your knees but do not squeeze it with your knees! Alternatively, put a jacket or coat under their head.
If possible, start timing from when the attack occurred and monitor the person. If the attack lasts longer than 5 minutes and the person does not regain consciousness, call an ambulance!
A prolonged attack can cause a stroke or even death of the person!
If the muscle spasms stops and the body becomes "flabby" try to put the person in a safe position. Never try to do this while they are convulsing!
The seizures subside and the person slowly regains consciousness. Never shout at the sick person and do not yank. Commotion or screams can trigger more epilepsy attacks!
