Epilepsy is a seizure disorder and therefore manifests clinically as seizure abnormalities, which can be functional abnormalities such as motor, sensory or mental behavior, but can be completely normal during intervals. The type of seizure, such as generalized or partial epilepsy, can be distinguished based on clinical symptoms combined with the EEG discharge site. The description of symptoms is very important in the classification of epilepsy, such as whether there are prodromal symptoms and aura before the seizure, whether the seizure starts with bilateral generalized involvement or starts in one area first and then gradually spreads in what way, whether there is any deviation or twisting of the head, eyes and trunk during the seizure, whether the seizure is normal immediately after the seizure or there is mental weakness and desire to sleep, and whether the interstitial period can be completely normal. It is best to record the entire seizure process with a camera or cell phone during the seizure and bring it to the doctor when you see him/her for a more accurate diagnostic classification.
