Seizure - first aidDefinition Return to top
Convulsions are when a person's body shakes rapidly and uncontrollably. During convulsions, the person's muscles contract and relax repeatedly.
The term "convulsion" is often used interchangeably with "seizure," although there are many types of seizure, some of which have subtle or mild symptoms instead of convulsions. Seizures of all types are caused by disorganized and sudden electrical activity in the brain.
Considerations Return to top
Convulsions can be unsettling to watch. Despite their appearance, most seizures are relatively harmless. They usually last from 30 seconds to 2 minutes. However, if a seizure is prolonged, or if multiple seizures happen and the person doesn't awaken in between, this is a medical emergency.
If a person has recurring seizures, and there are no underlying causes that can be identified, that person is said to have epilepsy. Epilepsy can usually be controlled well with medication.
Pay attention to which arms or legs are shaking, whether there is any change in consciousness, whether there is loss of urine or stool, and whether the eyes deviate in any direction.
