Area of Science:

  • Neurology
  • Pulmonology
  • Cognitive Science

Background:

  • Chronic obstructive pulmonary disease (COPD) is a progressive lung disease.
  • Cognitive impairment is increasingly recognized as a comorbidity in COPD patients.
  • Understanding the relationship between COPD and cognitive function is crucial for patient care.

Purpose of the Study:

  • To characterize cognitive domain impairments in COPD patients.
  • To clarify the relationship between COPD and cognitive dysfunction.
  • To determine the prevalence of cognitive impairment in COPD.

Main Methods:

  • Systematic review of literature.
  • Databases searched: PubMed, Scopus, ScienceDirect.
  • Inclusion criteria: studies on cognitive impairment in COPD patients.

Main Results:

  • Significant relationship established between COPD and cognitive impairment.
  • Memory and attention are the most affected cognitive domains.
  • Prevalence of visuospatial and intermediate visual memory impairment at 26.9% and 19.2% respectively.
  • Cognitive impairment correlates with COPD severity and comorbidities.

Conclusions:

  • COPD patients exhibit considerable impairment in memory and attention.
  • Cognitive deficits are associated with disease severity and comorbidities.
  • Further research needed on cognitive domains across different COPD stages.
