A severe, often violent involuntary contraction of the muscles. Convulsions may be caused by high fevers or poisoning and often accompany such diseases such as epilepsy.

A series of involuntary contractions of the voluntary muscles. Convulsive seizures are symptomatic of some neurological disorder; they are not in themselves a disease entity. In animals, they are most often caused by infectious agents and toxins. Convulsions are also produced by any of a number of metabolic disorders, such as hypoglycemia, hypocalcemia and hormonal imbalances; brain cell injury from head trauma, tumors and degenerative neural disease; anoxia and hemorrhage which deprive brain cells of vital substances; and acute cerebral edema which interferes with normal brain cell function. Epilepsy is also a cause of convulsions in dogs and cattle. Called also fit, ictus. See also seizure.
