Dental Dictionary: convulsion
(kənvul′shən)
n

An intense seizure.

 
sudden, violent, involuntary contraction of the muscles of the body, often accompanied by loss of consciousness. It is not known what causes the abnormal impulses from the brain that result in convulsive seizures, since the disturbance may arise in normal brain tissue as well as in diseased or injured tissue. Convulsions may occur in such conditions as epilepsy, poisoning, high fever (especially in young children), disturbances of calcium or phosphorus metabolism, alkalosis, diabetes, oxygen insufficiency, and a low blood-sugar content, as well as in local irritation or injury of the brain. Persons undergoing convulsions should be guarded against self-injury (see epilepsy). Otherwise, treatment must be directed to the underlying cause.


 
Health Dictionary: convulsion

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.

  • inherited c. and ataxia of cattle — see familial convulsions and ataxia of cattle.
