Seizures, also commonly referred to a convulsions, is a loss of consciousness with sudden uncontrolled contractions of the muscles. There are two types; rapid and slow. Convulsions may be linked to more serious, underlying conditions like epilepsy or tumors. Some convulsions are also of mysterious origin and they stop as quickly as they begin.
Sometimes a seizure will be preceded by the face becoming flushed, a general attitude of irritability, gritting of the teeth, and then twitching of the muscles and the fingers closing over the thumb. They often happen without warning. The body may become rigid, the eyes become fixed and staring, the head draws back and breathing seems to be suspended. The person having a convulsion may appear somewhat blue. And the muscles may go into spasm. The eyes may roll, the limbs jerk about and there may be some contortion of the face. The tongue may be bitten during the course of the episode. Sometimes the bladder and bowel release as well. Convulsions may be followed by a sound sleep or a coma.
Seizures can be caused by fever, gastrointestinal irritability, teething in infants, intestinal parasites, or diseases like pneumonia, smallpox, scarlet fever, epilepsy or measles. Newborns may suffer convulsions when instruments have been used in the delivery. Some children may have convulsions after a bad fright. Other causes may be due to tumors, hydrocephalus or meningeal hemorrhage. It is thought that when convulsions occur, the brain cells are sending out abnormal signals.
Seek medical assistance if you experience an episode as convulsions may be a symptom of a more serious underlying condition that needs to be diagnosed.
