The term handicapped refers to a person who has a physical or mental disability that limits their ability to carry out daily activities. The term is often used interchangeably with disabled, and can refer to conditions such as cerebral palsy, spina bifida, muscular dystrophy, hearing impairments, visual impairments, learning difficulties or intellectual disabilities, among others. Handicapped individuals may require assistance in performing tasks that able-bodied people take for granted, and they often face social, economic, and physical barriers to participation in society. The term handicapped is generally considered outdated and politically incorrect, with many preferring the terms "disabled" or "differently abled."
