Different types of seizures
The eyes roll back, the muscles become stiff, arms and legs move a lot (the individual can also bite his/her tongue, release urine, move their mouth a lot).
What you should do:
Lay the person down, protect them from possible damage, move furniture away and place pillows or clothes under the individual's head. Do not try to hold the individual down or to put things in the person's mouth. Call 112, contact an ambulance and ask for help!
If the person recovers from the attack, keep the individual in the recovery position while looking for breathing and heart rate. Give CPR until ambulance arrives if the individual is not breathing.
Do not put anything in the mouth of someone who has a seizure as it can damage teeth and make breathing difficult. Do not resist if an arm or leg twitches.
