The causes of high fever convulsions in children are as follows: a. There is some connection between a child’s high fever accompanied by convulsions and heredity, and some children’s parents have had this condition when they were young. Many parents worry that their child’s convulsions will cause epilepsy, which would be an excessive worry. Except for a family history of epilepsy, the likelihood of a child’s convulsions turning into epilepsy is almost negligible. Second, some children have convulsions during high fever because of birth injuries, where the child was born with trauma or asphyxia. If a child has convulsions whenever he has a fever, and there is no cause after examination, it may be caused by epilepsy. 4. If the child has a brain tumor, it may also cause convulsions, along with vomiting and headache symptoms. This requires a detailed examination. These are the most important causes of febrile convulsions in children. If you find that your child has an abnormality, you must seek medical attention in time.
