This chapter reviews the electroencephalographic changes associated with migraine, stroke and cerebral ischaemia, and their interpretation to aid in their differential diagnosis. The incidence of stroke and cerebral ischaemia is increasing with population aging. They are some of the most common problems faced in emergency medicine, and their diagnosis can be puzzling. This chapter describes and illustrates the patterns seen in such conditions, such as slowing, frontal intermittent delta activity (FIRDA), periodic lateralized epileptiform discharge (PLED), generalized periodic lateralized epileptiform discharge (GPED), and bilateral periodic lateralized epileptiform discharge (BiPED). The chapter reviews their prognostic value in critical care medicine and their differential diagnosis with status epilepticus.
