      condition characterized by violent, uncontrolled spasmodic contractions and relaxations of the voluntary muscles (muscle). Convulsions may be a symptom resulting from various conditions and diseases, such as epilepsy, uremia, eclampsia, rabies, tetanus, strychnine poisoning, and cerebral tumour. They are usually accompanied by loss of consciousness. During a convulsion the individual's clothing should be loosened around the neck, the head should be cushioned with a pillow, and any sharp or hard objects should be removed from the area. An object should never be inserted into the person's mouth during a convulsion. Medical treatment should be sought immediately after the convulsion ceases.
