Patient: Description (onset, main symptoms, hospital visited, etc.): My child is three and a half years old and has had convulsions since he was four months old. In May of this year, the number of seizures increased, and we have used levetiracetam and oxcarbazepine, which were not effective. We only had a sleep EEG more than a year ago, what other tests do we need to do and is it the same in our area? Patient: I hope the doctor will answer whether surgery is curable for this condition and what tests are needed before surgery. Chen Fuyong, Department of Neurosurgery, The First Hospital of Fujian Medical University: Hello! The key to whether epilepsy can be treated surgically is to find the abnormal brain tissue in the brain, and if it can be successfully found and removed, then epilepsy may be cured. This requires the doctor to look for all clues to find the “bad guy” in the brain like a “police officer solving a crime”. These methods include: 1) seizure symptomatology, such as which side of the head and eyes are deflected, which side of the limb is twitching, etc.; 2) cranial MRI to see if there are abnormal changes in brain tissue within the skull; 3) functional neuroimaging, such as magnetic resonance spectroscopy, PET imaging, etc.; 4) video EEG, preferably to capture the seizure so that the origin of the discharge can be better identified; 5) Neuropsychological assessment. The above mentioned means are non-invasive. If this information is not well localized, or if the lesion is located in a functional area, then a second surgery is needed to place intracranial electrodes and then monitor video EEG to better identify the site of abnormal discharges and locate the functional area so that the epileptogenic focus can be safely removed.
