Description
Summary:Introduction COPD has multiple extrapulmonary manifestations and the latest studies have focused on cognitive dysfunction effects on sleep quality. The purpose of this study is to assess if there is a relationship between sleep quality and cognitive decline in COPD patients with severe airflow limitation. Methods We performed an observational study to determine if there is a link between cognitive function and sleep quality. The included patients were divided into two groups: a group with COPD patients and control group. We evaluated lung volumes, cognitive function, sleep quality and disease impact on the quality of life. Results Most of the COPD patients presented mild cognitive impairment (MCI) (95.7%), compared with only 24.1% in the control group (Pearson chi‐square χ2(1) = 42.560, p
