Can you have a seizure with no brain activity?
Some people experience symptoms similar to those of an epileptic seizure but without any unusual electrical activity in the brain. When this happens it is known as a non-epileptic seizure (NES). NES is most often caused by mental stress or a physical condition.
What causes mini brain seizures?
Causes of simple partial seizures include traumatic brain injury, which can cause a scar on the brain that can disturb normal brain electrical signals and trigger seizures. Also, brain irritation from surgery, stroke, or tumor can interfere with brain electrical activity and cause simple partial seizures.
What does a small brain seizure feel like?
Simple focal seizures: They change how your senses read the world around you: They can make you smell or taste something strange, and may make your fingers, arms, or legs twitch. You also might see flashes of light or feel dizzy. You’re not likely to lose consciousness, but you might feel sweaty or nauseated.
What part of the brain causes seizures?
The temporal lobe processes memories, integrating them with sensations of taste, sound, sight and touch. Frontal lobe seizures are a common form of epilepsy, a neurological disorder in which clusters of brain cells send abnormal signals and cause seizures.
What does a tonic seizure look like?
A tonic-clonic seizure usually begins on both sides of the brain, but can start in one side and spread to the whole brain. A person loses consciousness, muscles stiffen, and jerking movements are seen. These types of seizures usually last 1 to 3 minutes and take longer for a person to recover.
When is it necessary for you to get medical attention during a tonic-clonic seizure?
Tonic-clonic seizures last between one and three minutes. Any seizure lasting longer than 5 minutes will need medical attention.
What triggers a tonic-clonic seizure?
It’s the type of seizure most people picture when they think about seizures. A grand mal seizure — also known as a generalized tonic-clonic seizure — is caused by abnormal electrical activity throughout the brain. Usually, a grand mal seizure is caused by epilepsy.
Can you be conscious during a tonic seizure?
A person may be aware or have only a small change in awareness during a tonic seizure. They usually happen during sleep and usually involve all or most of the brain, affecting both sides of the body.
What to do if someone has a tonic seizure?

- Give them room. Keep other people back.
- Clear hard or sharp objects, like glasses and furniture, away.
- Cushion their head.
- Loosen clothing around their neck, if you can safely.
- Don’t try to hold them down or stop their movements.
