A seizure is an uncontrolled burst of electrical activity between brain cells that can cause temporary abnormalities in muscle tone or movements, behaviors, sensations or states of awareness.
Seizures can come on suddenly and can range from nearly unnoticeable to causing unconsciousness and convulsions.
It is important to provide first aid for any type of seizure
and to stay with the person until the seizure ends and they are fully awake.
Seizures are caused by an overload of electrical activity in the affected areas of the brain.
A seizure is a burst of uncontrolled electrical activity between brain cells (also called neurons or nerve cells) that causes temporary abnormalities in muscle tone or movements (stiffness, twitching or limpness), behaviors, sensations or states of awareness.
Seizures are not all alike.
