A : A convulsion is a type of seizure. Not all seizures are convulsions. Some seizures involve staring spells (petit mal or absence seizures). Some seizures involve certain almost purposeful activity that is the same each time. Some seizures can involve only one limb without loss of consciousness. A grand mal (also called major motor seizure) involves loss of consciousness, rigidity of the body followed by jerking motions of the whole body. This is followed by a period of unresponsiveness called the post ictal state. There is a type of convulsive seizure that happens in young children with fever. Alcohol withdrawal can also cause seizures.
