Video Summary

The webinar titled "Ask the Expert: How Do We Know We Have Missed the SEEG Seizure Onset Zone?" featured Dr. Philip Kahan and Dr. Jaysing Singh discussing methods to identify and handle situations where SEEG might miss the seizure onset zone. Dr. Kahan highlighted SEEG as a useful technique for pre-surgical evaluation of drug-resistant epilepsy but noted its potential pitfalls, such as missing the seizure onset due to limited electrode coverage. The webinar explored various case studies, addressing how to recognize missed seizure onset, interpret SEEG patterns, and decide on interventions like adding electrodes, performing radiofrequency thermocoagulation, or opting for surgery. Dr. Kahan emphasized the importance of forming strong hypotheses regarding seizure onset locations before SEEG procedures, using insights from seizure semiology, EEG, MRI, and PET scans. Participants were invited to engage with the presented cases and share their opinions on appropriate actions. The session aimed to deepen understanding of SEEG's complexities and improve patient outcomes by refining diagnostic and surgical approaches.
