Abstract
At the highest level, epilepsy syndromes are classified as being either focal or generalised (Commission on Classification and Terminology of the International League Against Epilepsy 1981, 1989). Focal epilepsies appear to arise from a localised part of the brain and then spread (Commission on Classification and Terminology of the International League Against Epilepsy 1989). They are usually identified by pinpointing the onset of seizures from a specific location, and there will often be a focal structural abnormality. A more challenging problem for imaging is understanding the structures involved in idiopathic generalised epilepsy (IGE), which does not have identifiable lesions and appears to arise bilaterally and symmetrically throughout the brain (Blumenfeld 2005; Commission on Classification and Terminology of the International League Against Epilepsy 1989).
