Elder maltreatment is a global public health crisis. This chapter provides an overview of maltreatment which includes abuse, neglect, and exploitation. It describes cultural components of maltreatment and the consequences it can have on victims. It draws on generic definitions of maltreatment that can be used cross-culturally, provides examples, and signs of specific types of maltreatment, and addresses both maltreatment that is perpetrated by others and abuse which is inflicted on oneself. Scams are included as they are increasingly common and can have significant negative effects on the well-being of older adults. Screening tools, trainings, and other resources are described to enhance knowledge and create awareness. The reporting of elder maltreatment is discussed in an American context, as the authors of this chapter are based in the United States.
