AES 2023 Epilepsy Specialist Symposium | The Frontal Lobe: Bermuda's Triangle

The frontal lobes are the largest lobes of the human brain composing over 40% of the total cerebral cortex volume. There is a wealth of behavioral and seizure semiology symptoms that can arise from it. Simplified, the frontal lobe can be viewed as a triangular body with 3 main surfaces: medial, dorsolateral, and basal / orbito-frontal. Its size and complexity pose challenges in the diagnosis, localization, and treatment of focal epilepsies arising from this area. A forgotten, transverse triangular coronal EEG montage attempted to assess deep frontal and temporal lobe structures. In this symposium, we address the intricacies of the frontal lobe, starting with its anatomy, aura seizure presentation, cognitive/behavioral correlates, genetics/imaging correlates, and surgical approaches
