Patient: My daughter, who will be 2 years old in two days, had a convulsion at 2:00 p.m. on June 28, 2008, when she felt her body temperature was very high and had a convulsion after taking antipyretic medicine for a while, and started rolling her eyes, twisting her mouth to change her movements, and holding her body up one after another, reporting to the hospital downstairs with her eyes staring, her face expressionless, and her body not moving. 10 minutes or so later, she arrived at the hospital with stiff limbs. He would only cry after a shot of Valium. I would like to ask you what further tests should be done on my child to prevent him from having another convulsion and to rule out whether he has epilepsy. Due to the long duration of the two convulsions, will there be any adverse effects such as brain damage? Do I need to take medication? Doctor: If the fever convulsions are only high, you may not get epilepsy in the future. If there are no febrile convulsions in the future, epilepsy is more likely. If you have a history of febrile convulsions, you are more likely to get epilepsy later than if you do not have febrile convulsions. If you have only 2 febrile convulsions, you can observe them for now and do not need to take medication. It is important to pay attention to prevent the recurrence of the causes of hyperthermia. There are two preliminary tests, one is EEG and the other is cranial MRI. Patient: Can febrile convulsions be hereditary? If you have a family history of febrile convulsions, such as grandfather, father and other relatives who had a history of febrile convulsions when they were young, and not only did not have febrile convulsions and seizures again when they were older, but all aspects of brain function are normal, then if the child has febrile convulsions now, it is generally more optimistic, and when he grows up, he will be like other relatives in the family who had febrile convulsions when they were young. The child’s febrile convulsions are usually optimistic and will usually heal on their own when they grow up, just like other relatives in the family who had them as children.
