Summary

Cognitive impairment and disability both increase with age and are linked. Addressing risk factors for both may delay dementia and reduce risks of death and institutionalization.

Area of Science:

  • Gerontology
  • Neuroscience
  • Public Health

Background:

  • Disability and cognitive impairment prevalence increases with age.
  • A link exists between cognitive impairment and disability, irrespective of other factors.

Purpose of the Study:

  • To review the literature on the relationship between cognitive impairment and disability.
  • To identify specific instrumental activities of daily living (IADL) related to cognitive impairment.
  • To discuss implications for prevention and future research.

Main Methods:

  • Literature review of published studies.
  • Analysis of cross-sectional relationships.
  • Identification of specific IADL items linked to cognitive function.

Main Results:

  • Cognitive impairment and disability are distinct but related concepts.
  • Low cognitive performance predicts future functional impairment.
  • Both conditions elevate risks of mortality and institutionalization.

Conclusions:

  • Preventive strategies targeting risk factors for cognitive impairment and disability are crucial.
  • Further research is needed to understand cognition's role in disablement, especially in community-dwelling elderly.
  • Separate assessments for cognition and function are necessary.
