In some contexts it is defined in terms of health conditions; in other contexts it is defined in terms of functional limitations; and in still other settings it is defined in terms of activity and role limitations. These varying definitions of disability have in some cases been codified into law, into standardized data collection instruments, and into the practice framework of professionals and organizations that serve people with disabilities. One consequence of the different ways in which disability is defined is that before the characteristics and needs of people with disabilities can be discussed, the parameters of the disability definition being used must be addressed. Whatever the specific components of the definition, there does appear to be some consensus that a person with a disability is someone who experiences limitations in function as a consequence of a permanent physical or mental impairment or a chronic health or mental health condition in interaction with the person's environment. The health condition or impairment may be one that is visible, or it may be invisible. Onset may occur at any age or it may be present at birth. Finally, the severity of disability may vary, even among people with the same condition or impairment, such that some individuals may find it difficult to participate in many life activities, while others experience the effects of disability in a single area.
