Seizures occur as a result of irregular or sudden electrical activity in the brain. They can cause convulsions or shakes, usually lasting between 30 seconds and 2 minutes. Some seizures are milder and don’t cause convulsions. Focal seizures occur in part of the brain, while generalized seizures occur in the entire brain.

There are a lot of possible causes for seizures, including reactions to certain drugs or medications, head injuries, high fevers,  and disorders like epilepsy. Many doctors feel that people with seizure disorders or on seizure medication should not consume energy drinks.
