Outcomes included anxiety (Hospital Anxiety and Depression Scale (HADS)-A), depression (HADS-D and Patient-Health Questionnaire (PHQ)-9) and cognitive function (Montreal Cognitive Assessment (MoCA)).All outcomes showed statistically and clinically significant improvements after 12 weeks independent of treatment group. However, greater improvements in HADS-A and MoCA were seen in patients who exhibited greater increases in physical activity and exercise capacity, respectively, whereas greater improvements in HADS-D and PHQ-9 were seen in patients who exhibited increases in either physical activity or exercise capacity.The results indicate that SMBM with/without bronchodilators or ExT was associated with improved psychological and cognitive functioning. Anxiety reduced with increased physical activity, cognitive function improved with increased exercise capacity, and depression reduced with increases in either physical activity or exercise capacity. Interventions that increase daily physical activity or exercise capacity may improve psychological and cognitive outcomes in COPD.Behavioural modification adjunct to bronchodilator therapy and exercise training to increase exercise capacity and physical activity can also be beneficial for improving anxiety, cognitive function and depression in patients with COPD http://bit.ly/33ZufNM ER -
