Disability is broadly defined as the consequence of an impairment that may be physical, cognitive, mental, sensory, emotional, developmental, or some combination of these. A disability may be present from birth, or occur during a person's lifetime. Disabilities is an umbrella term, covering impairments, activity limitations, and participation restrictions. Impairments may include physical, sensory, and cognitive or developmental disabilities. Mental disorders (also known as psychiatric or psychosocial disability) and various types of chronic disease may also qualify as disabilities, (Different countries, regions, and even organisations often define disability in a similar - but slightly different manner). A disability may occur during a person's lifetime or may be present from birth.
