Convulsions are an emergency condition in which involuntary contraction of the whole body or local skeletal muscle groups is caused by excessive excitability and abnormal discharge of nerve cells in the brain due to different causes. There are many causes of convulsions, mainly including: infectious and non-infectious. Infectious factors are mostly intracranial infectious diseases: including intracranial infections caused by various bacteria, viruses, mycoplasma, tuberculosis, and so on. In addition, when bacterial infections from other parts of the body enter the bloodstream, the toxins may also cross the blood-brain barrier and act on the central nervous system to produce convulsions. Non-infectious factors are most common in intracranial non-infectious diseases; including intracranial hemorrhage, craniocerebral trauma, intracranial tumors, craniocerebral malformations, and central nervous system malformations. Both infectious and noninfectious diseases require prompt symptomatic management whenever convulsions occur. In the case of hyperthermic convulsions, the first step can be to reduce heat, either physically or medically, for rapid fever reduction. If the convulsions are caused by abnormal lesions in the brain or by trauma, the necessary tests should be carried out promptly to treat the cause. In short, there are many causes of convulsions, so you need to go to the hospital to identify the cause and treat it under the guidance of a doctor. Do not use drugs blindly.
