The terms "impairment" and "disability" are often used in the context of health and functional limitations, but they have distinct meanings:

  • Impairment: Refers to a problem with a structure or organ of the body, such as a loss of a limb, loss of vision, or memory loss. Impairments are usually the result of disease, illness, or injury and occur at the level of tissue or organs.
  • Disability: Refers to a functional limitation with regard to a particular activity, resulting from an impairment. Disability means that a person has difficulty performing an activity, such as getting dressed or bathing without help, due to their impairment.

In summary, impairment is a loss or abnormality of psychological, physiological, or anatomical structure or function, while disability is the restriction or lack of ability to perform an activity due to the impairment.
