Prior to surgery, we gather a lot of information about the seizures, the cause of the child’s epilepsy and the brain structure. We capture typical seizures during an inpatient video EEG study, and we will often lower medication to encourage a seizure to happen. We use detailed imaging techniques to look at the brain structure and how the brain uses energy, to see if we can pinpoint a focal seizure onset zone. We will also do neuropsychological testing, to understand if a child has difficulties in certain brain functions. We will discuss the results with our multidisciplinary epilepsy team, and evaluate if the child could benefit from epilepsy surgery.
