A CT scan of the head does not reveal whether a patient has epilepsy. The diagnosis of epilepsy does not rely on imaging, but rather on a thorough and accurate medical history. In general, the diagnosis of a patient is based on the clinical manifestations of the seizure, the triggers before the seizure, and the past medical history, and does not rely on auxiliary tests, which can only be used as a basis to help further confirm the diagnosis. Usually, the patient’s family members or colleagues will provide detailed clinical manifestations of the patient’s seizures for the doctor to make a judgment. If there is an EEG test suggestive of epileptic waves, such as sharp, spiky, sharp-slow, and spiky-slow waves, the diagnosis of epilepsy can be further confirmed. As for the cranial CT or MRI, it is not to confirm the diagnosis of epilepsy, but to check whether there is any intracranial organic disease causing seizures, it is a kind of etiological examination.
