Fever seizures (febrile convulsions) are the most common cause of a single seizure, especially in children. It is important to rule out a serious illness that may have caused the seizure. But if you have a first-time seizure, you should be checked by your doctor. Having one seizure does not always mean that a serious health problem exists. For instance, a sharp blow to the head may cause a seizure. Any normally healthy person can have a single seizure under certain conditions. A single seizure usually lasts less than 3 minutes and is not followed by a second seizure. Many medical conditions can cause a type of body shaking that usually affects the hands and head ( tremors).ДЄ small number of people will have only one seizure during their lifetime.

Not all body shaking is caused by seizures. Afterwards, the person does not remember the episode. Although the person is awake, he or she does not respond normally. Some people who have seizures have symptoms before the seizure ( auras) or briefly lose touch with their surroundings and appear to stare into space. Shaking of the body, either mild or violent, does not always occur with seizures. Other people may become unconscious and have violent shaking of the entire body. Some people have only slight shaking of a hand and do not lose consciousness.

Seizures are different from person to person. Seizures, or convulsions, occur when abnormal signals from the brain change the way the body functions. The brain controls how the body moves by sending out small electrical signals through the nerves to the muscles.
