Epilepsy with a clear cause is medically known as secondary epilepsy, or symptomatic epilepsy. In addition, some epilepsies without organic and metabolic brain disease manifestations, whose causative agent is not yet known, are called primary epilepsies, or idiopathic epilepsies. Some people also suggest that this type of epilepsy is called cryptogenic epilepsy, because with the continuous development and progress of medical science and technology, the causes of epilepsy will be continuously identified and discovered. There are many triggers for epilepsy, and seizures can be caused by personal, environmental, and genetic factors. What factors can cause epilepsy in patients themselves 1. acute and chronic renal failure, hypoglycemia, hypocalcemia, hypertensive encephalopathy, islet adenoma, hyperthyroidism; 2. vitamin B6 deficiency; 3. various systemic infections; 4. long-term use of hypnotics; 5. sudden withdrawal from alcoholism; 6. sudden discontinuation of antiepileptic drugs; 7. carbon monoxide poisoning can induce epilepsy. Understanding these self factors that may induce epilepsy can help people better understand epilepsy and at the same time better prevent and treat it in their lives.
