Today, older adult abuse is also called elder abuse and elder mistreatment, and was originally termed battered old person syndrome by Butler. Older adult abuse increases an older adult’s risk for morbidity and mortality. Older adult abuse is a multifactorial phenomenon that includes single or multiple acts of abuse. The abuse may be emotional, financial, physical, sexual, or self-induced. The higher frequency of older adults who are abused using emergency room resources with subsequent admissions to hospitals or nursing homes adds social and economic burdens to societies worldwide. There are two types of older adult self-abuse: self-neglect and self-harm. Both types of self-abuse threaten the morbidity of older adults and are a risk for mortality. The older inmates who have the highest risk of older adult abuse are disabled inmates and those older inmates experiencing dementia.
