Elder abuse refers to any intentional act or lack of appropriate action that harms an elderly person. It can include physical, psychological, sexual, financial abuse, and violation of personal rights. Around 1 in 6 elderly people experience some form of abuse. The main abusers are often sons and daughters-in-law. Signs of abuse include unexplained injuries, weight loss, and inconsistent stories from the elderly person and their caregiver. Prevention strategies include education, awareness campaigns, and ensuring elderly people's basic needs for food, shelter, and healthcare are met.
