The clinical diagnosis of epilepsy relies on the following: 1. accurate history and physical signs. 2. electroencephalogram. In principle, the seizure EEG is one of the most valuable auxiliary examinations. The total positive rate is only about 80% to 90% during the interictal period, even when combined with the evoked test and 24-hour continuous tracing, so the clinical diagnosis must be combined with the medical history and physical examination and other aspects for comprehensive analysis. The diagnosis of epilepsy should not be denied because the EEG is negative, and the diagnosis cannot be confirmed if the EEG is positive without clinical manifestations. As long as the clinical manifestations are typical, the diagnosis can usually be made, and attention should be paid to strengthen the examination of EEG. 3, imaging and laboratory tests. 4. The effect of antiepileptic drugs. In general, as long as the clinical diagnosis is correct, the selected drugs are accurate, the amount used is appropriate, and the method of taking them is reasonable, satisfactory results will be received, so in a certain sense, the effect of drugs is also an important aspect in determining whether the diagnosis is correct or not.
