refers to a sudden attack involving uncontrollable muscular
contraction and relaxation. The person experiencing the convulsion
may appear to shake uncontrollably, and the convulsion may
include either a part of the body or the entire body.
Convulsions are a common manifestation of
seizures in epilepsy,
although some seizures do not involve any visible motor symptoms.
Convulsions may also be caused by various conditions including
meningitis, brain lesions, fever, and various kinds of poison,
such as strychnine or cyanide poisoning.
If you observe someone having a convulsion,
the most important thing is to protect the patient from injury.
Cradle the head or place something soft underneath it, remove
any nearby sharp objects, and loosen tight clothing -- but
do not try to hold the patient still. Do not put anything
into the mouth; people cannot "swallow" their tongues. However,
the head can be turned sideways to allow the tongue to fall
away from the airway.
In many cases (particularly in children),
convulsions stop by themselves after a few minutes. In some
cases, convulsions are a symptom of a life-threatening condition,
such as poisoning or meningitis. If you do not know what is
causing the convulsion, or if the convulsion continues for
more than five minutes, it is important to get the patient
to a hospital as quickly as possible.
