Abstract

We conducted a systematic review of 23 original studies published from 2010 to 2022, which participated a total of 168 thousand people, including 48 thousand patients with chronic obstructive pulmonary disease (COPD) aged 45 to 93 years.Results. The prevalence of cognitive impairment (CI) in patients with COPD varies from 6 to 63%. COPD patients have a higher risk of developing mild CI (HR from 1.1 to 1.9; OR from 1.4 to 2.4) and dementia (HR from 1.3 to 1.9; OR = 1.2). The risk of cognitive dysfunction increases along with a decrease in the values of forced expiratory volume in one second as a percentage of its expected value (FEV1%) (OR = 1.34), arterial oxygen partial pressure (PaO2) (OR = 5.45), oxygen saturation (SaO2) and an increase in the level of arterial carbon dioxide partial pressure (PaCO2). There is a significant direct relationship between FEV1% and Mini-Mental State Examination (MMSE) (p < 0.0001) and an inverse relationship between COPD severity and MMSE (p < 0.0001). The MMSE score is correlated with FEV1% (r = 0.46, p < 0.01) and PaO2 (r = 0.43, p < 0.05).Conclusion. The available data confirm the association of COPD with an increased risk of occurrence and progression of CI. It is discussed that this is due to the unfavorable course of concomitant vascular and neurodegenerative diseases against the background of chronic hypoxia.
