The brain controls how the body moves by sending out small electrical signals through the nerves to the muscles. Seizures, or convulsions, occur when abnormal signals from the brain change the way the body functions.
Seizures are different from person to person. Some people have only slight shaking of a hand and don't lose consciousness. Other people may become unconscious and have shaking of the entire body.
Shaking of the body doesn't always occur with seizures. Some people who have seizures have symptoms before the seizure (auras). Or they may briefly lose touch with their surroundings and seem to stare into space. The person is awake. But they don't respond normally. Afterward, the person doesn't remember the episode.
Some people will have only one seizure during their lifetime. A single seizure usually lasts less than 3 minutes and isn't followed by a second seizure. Any healthy person can have a single seizure under certain conditions. If you have a first-time seizure, you should be checked by your doctor. It's important to rule out a serious illness that may have caused the seizure.

If you witness a seizure, try to stay calm. Pay close attention to what happens during and after the seizure. How you describe the seizure afterward will help a doctor diagnose and treat the person. For example, how did the person's body move? How long did the seizure last? How did the person act before and right after the seizure? Did the person have any injuries from the seizure?
No matter what caused the seizure, there are things you can do to help a person who is having a seizure.
Keep them from falling if you can. Or try to guide the person gently to the floor.
But be careful not to apply too much pressure to the body.
Putting something in the person's mouth may cause injuries, such as chipped teeth or a fractured jaw. You could also get bitten.
This can cause injury, such as a dislocated shoulder.
No matter what caused the seizure, you can help someone after they've had a seizure.
If you couldn't turn the person during the seizure, do it when the seizure ends and the person is more relaxed.
If the person is having trouble breathing, call 911.
Most people will be sleepy or confused after a seizure.
