There are relatively few true psychiatric emergencies, but there are some important situations where prompt intervention is required. In this chapter, these will be discussed with an emphasis on recognition and basic management. These are also conditions that you may come across as doctors in other specialities, which is why we have included them here. In this chapter there will be some overlap with Chapters 12 and 18. However, to help your learning we have cross-referenced to reduce repetition but have also included information in this chapter to enable you to consider the particular issue in the context of an emergency.
