Seizures are changes in the brain’s electrical activity. These changes can cause dramatic, noticeable symptoms, or in other cases no symptoms at all.
The symptoms of a severe seizure include violent shaking and a loss of control. However, mild seizures can also be a sign of a significant medical problem, so recognizing them is important.
Because some seizures can lead to injury or be a sign of an underlying medical condition, it’s important to seek treatment if you experience them.
