Elder abuse is generally defined as the maltreatment of individuals over the age of 60, although no precise definition exists in the literature. Types of abuse include, but are not limited to, psychological/emotional, physical, sexual abuse, and financial exploitation. Certain risk factors exist leaving an individual more susceptible to abuse, and many obstacles exist preventing the elimination of abuse. There are also identifiable risk factors that increase the likelihood of perpetration of abuse. This systematic review provides an overview of the scope of the problem, types of abuse, risk factors, characteristics of abusers, and key aspects of elder abuse prevention.
