A convulsion, medically known as a seizure, is an abnormal synchronized discharge of brain cells throughout the cerebral cortex that results in a convulsive seizure of the limbs. If a patient experiences such symptoms once in a while, it can be called a seizure, but if the patient will experience such symptoms frequently, it may be diagnosed as epilepsy. Epilepsy is divided into primary epilepsy and secondary epilepsy: i. Primary epilepsy: the age of onset is relatively young, no specific cause is usually found, and no intracranial organic disease is found but seizures occur. The primary seizures can be divided into two main forms: grand mal and petit mal. 1. grand mal seizures: manifested as a sudden fall of the patient, with convulsions, double eye stare, both eyes turned upward or to the side and squinting, then foaming at the mouth, breathing heavily, even biting the tongue, etc., and also accompanied by tonic and paroxysmal seizures of the limbs, urinary incontinence, etc. 2. petit mal seizures: manifested as a sudden loss of consciousness, that is The activity being carried out suddenly stops, but this seizure generally lasts a short time, may be tens of seconds to recover. Second, secondary epilepsy: refers to epilepsy caused by intracranial organic diseases, such as encephalitis, brain tumors, cranial trauma, hemorrhage, cerebrovascular disease, etc. Postoperative scars can also cause abnormal whole-brain discharges thus leading to secondary epilepsy. After epilepsy occurs, patients should go to the neurology department of the hospital for examination, and if diagnosed, they need to undergo targeted treatment under the guidance of professional doctors. At the same time, patients should get sufficient rest and avoid drinking alcohol to promote physical recovery.
