Key result
Dyspnea severity was strongly negatively correlated with cognitive status in patients with COPD (r=-0.705, p<0.001), with 58.7% of patients exhibiting cognitive impairment.
Why the study?
The study was conducted to examine the effect of dyspnea on cognitive status in patients with chronic obstructive pulmonary disease.
Cross-Sectional (n=315)
Yes
In patients with COPD, higher levels of dyspnea are strongly associated with worse cognitive status, suggesting a need for dyspnea management to preserve cognitive function.
Should not yet change COPD practice; leaves open whether dyspnea reduction improves cognition.
Aim: The aim of this study is to examine the effect of the dyspnea on cognitive status in patients with chronic obstructive pulmonary diseases (COPD). Material and Methods: The universe of this descriptive study consist of 315 COPD patients. Data were collected with a Questionare, Medical Research Council Scale (MRCS) and Standardize Mini Mental State Examination (SMMT-E). In the analyses of the data, descriptive statistics, independent t-test, oneway analysis of variance and regression and Tamhane T2 analysis were employed. Results: The mean age of the patients patricipating the study was 54.06 (11.41) years. 38% of the patients were determined to experienced moderate dyspnea (2.20±0.95). The patients’ cognitive status mean scores were found low (21.38±5.74) and 58.7% had cognitive impairment. It was determined in multiple regression analysis that severe dyspnea level, inadequacy in dyspnea management, associating dyspnea with breathlessness, feeling of low mood and fear of death, use of oxygen tube and bipod at home were associated with cognitive status. Moreover, it was found that 31% of the variance in the cognitive level of the patients was explained by the independent variables related to dyspnea (R2 = 0.581; adjusted R2= 0.311). It was found that there was a strong positive correlation between dyspnea and cognition status (r=-0.705, p=0.000). Conclusion: It was determined that dyspnea effects to SMMT-E and therefore it could be advised to taking measures to reduce dyspnea COPD patients.

ŞANLITÜRK et al. (2023) conducted a cross-sectional in Chronic Obstructive Pulmonary Disease (COPD) (n=315). Dyspnea vs. Lower levels of dyspnea was evaluated on Cognitive status (SMMSE-U score) (r=-0.705, p=<0.001). Dyspnea severity was strongly negatively correlated with cognitive status in patients with COPD (r=-0.705, p<0.001), with 58.7% of patients exhibiting cognitive impairment.
