Patient's question:
My child began experiencing symptoms similar to epilepsy again when they were 4 years old. Why is that? We had an MRI, brain CT, a 24-hour monitoring device, and an EEG, but none of the tests revealed anything. Later, during a recurrence, the EEG showed similar epilepsy waves. We took many medications for about a year, but the seizures still recurred. I don't know if an EEG diagnosis is the most effective.Doctor's answer:
An electroencephalogram (EEG) is the most effective diagnostic tool for confirming epilepsy. If combined with various provocation methods and special electrodes, it can detect abnormal epileptic waves in at least 80% of patients. EEG testing can help determine how epilepsy develops and plays a decisive role in the clinical diagnosis of atypical seizures and epilepsy classification, which are difficult to diagnose. EEG testing is of great significance for confirming the location of epileptic foci. For many epileptic foci without morphological changes, CT and MRI may show no abnormalities, and EEG is sometimes the primary method for localization.
