Epilepsy—diagnosis and assessment

This chapter explains the incidence, classification, and diagnosis of the common epileptic syndromes. There is particular emphasis on medical management including the emergency management of status epilepticus. For much of the nineteenth century, disorders of mood, behaviour, or personality were often labelled as epileptic in nature.
 More recently, there has been an acknowledgement of the socioeconomic burden of the condition, a recognition that it still carries a significant social stigma. Furthermore, as our understanding of neural networks has improved, novel techniques of neuromodulation have been developed as an adjunct to more traditional medical and resective therapeutic measures. The assessment of patients and the tests used to workup a patient prior to epilepsy surgery are also discussed in detail in this chapter, including an explanation of the invasive electroencephalography (EEG) techniques that may be used in complex cases.
