  • A child could be in a car crash and have traumatic brain injury, which may affect thinking and remembering.
  • A young adult can have depression or another mental illness, which may make it difficult to manage day-to-day stressful situations.
  • A woman in early midlife can develop multiple sclerosis, which may make it difficult to move around.
  • A college student with epilepsy whose seizures are stimulated by stress may need accommodations with activities such as long tests.
  • A man in late midlife can develop hearing loss, which may affect how he communicates.
  • An older adult can lose eyesight from glaucoma.

International Classification of Functioning, Disability and Health

The World Health Organization (WHO) has published the International Classification of Functioning, Disability and Health (ICF) in 2001. The ICF provides a standard language for classifying changes in body function and structure, activity, participation levels, and environmental factors that influence health. This helps to assess the health, functioning, activities, and factors in the environment that either help or create barriers for people to fully participate in society.

The ICF parts are presented here in modified form for easier reading. For more information, please visit the WHO website.
