Each day, news reports cite instances of older adults across the United States being abused, denied needed care, or financially exploited, often by those they depend on. The most recent study of the extent of elder abuse estimated that 14.1 percent of non-institutional older adults had experienced physical, psychological, or sexual abuse; neglect; or financial exploitation in the past year. Elder abuse has also been associated with negative effects on the victims' health and longevity. This book contains information on existing estimates of the extent of elder abuse and their quality; factors associated with elder abuse and characteristics and challenges of state Adult Protective Services for addressing elder abuse.
