disabled

A disability is any condition which makes it more difficult for a person to do certain activities or interact with the world around them. These conditions, or impairments, may be cognitive, developmental, intellectual, mental, physical, sensory, or a combination of multiple factors. Impairments causing disability may be present from birth or occur during a person's lifetime. The United Nations Convention on the Rights of Persons with Disabilities defines disability as:

long-term physical, mental, intellectual or sensory impairments which in interaction with various barriers may hinder [a person's] full and effective participation in society on an equal basis with others.
Disability is a contested concept, with different meanings in different communities. The term disability may refer to physical or mental attributes that some institutions, particularly medicine, view as needing to be fixed (the medical model); it may also refer to limitations imposed on people by the constraints of an ableist society (the social model); or the term may serve to refer to the identity of disabled people. Physiological functional capacity (PFC) is a measure of an individual's performance level that gauges one's ability to perform the physical tasks of daily life and the ease with which these tasks are performed. PFC declines with advancing age to result in frailty, cognitive disorders, or physical disorders, all of which may lead to labeling individuals as disabled. According to the World Report on Disability, 15% of the world's population or 1 billion people are affected by disability. A disability may be readily visible or of invisible in nature.
