Elder abuse is a hidden epidemic, with millions of older adults experiencing physical, psychological, or financial harm each year. However, the true extent of the problem is unknown due to under-reporting and lack of reliable data. This paper aims to provide an international perspective on the hidden epidemic of elder abuse, exploring the prevalence, risk factors, and consequences of this global issue. A systematic review of the literature was conducted using multiple databases. Studies from various countries were included to overview the problem comprehensively. The prevalence of elder abuse varies widely across countries, but it is estimated that at least 1 in 6 older adults experience some form of abuse. Risk factors include female gender, advanced age, cognitive impairment, and social isolation. Consequences of elder abuse include physical and psychological harm, premature death, and reduced quality of life. Elder abuse is a severe and pervasive global problem. The lack of reliable data and under-reporting makes it difficult to assess its prevalence and impact accurately. The review underscores the urgent need for a worldwide response to elder abuse tailored to consider cultural contexts and local resources. Collaborative efforts between governmental and non-governmental organizations are essential to raise awareness, provide education on elder rights, and implement effective prevention strategies. Establishing robust reporting mechanisms and support frameworks for victims of elder abuse is crucial for safeguarding the wellbeing of older adults worldwide.
