Disability includes long-term physical, mental health, intellectual, neurological or sensory differences which, in interaction with various attitudinal and environmental barriers, may hinder full and effective participation in society on an equal basis with others.
People with disability are a very diverse group. There are many types and there can be wide variations of impact on daily living. Many disabilities are not visible, such as anxiety, post-traumatic stress disorder, diabetes or dyslexia.
Disability is a natural part of human diversity and everybody is likely to experience disability at some point in life. Disability may be present from birth, acquired due to illness or accident, or come about with time as a result of age.
