For diagnosed epilepsy effective treatment should first be directed at the epilepsy itself. Some patients and families think that they should find out the cause of the appearance of epilepsy first and then treat it accordingly, which is a good idea. A clear diagnosis is important for the treatment of epilepsy, and it is also essential to figure out which type of epilepsy, which part of epilepsy, and what causes the epilepsy for targeted treatment. But the fact is that there is a proportion of epilepsy for which no clear cause can be identified, and if a grand mal seizure occurs during the process of seeking the cause, it can instead cause more harm to the patient. In addition, it is not necessary to find out the cause of the epilepsy if the cause is not clear after the necessary tests.
