The Relationships Among Pulmonary Function, Aerobic Fitness, and Cognitive Functioning in Older COPD Patients

Abstract: In an older COPD sample, age, aerobic fitness, and pulmonary function are predictive of cognitive performance on various tasks. In particular, age and aerobic fitness are predictive of speed of processing, which is a cognitive variable that may itself underlie performance on a majority of cognitive tasks.

“…They may experience age-related declines in blood flow, disease-related declines in arterial oxygen content, and both age-and disease-related declines in physical activity. 24 Our results are partly in agreement with these findings. On the other hand, another study investigating the relationship between aerobic fitness and cognition in a sample of subjects with COPD found that no significant relationships between exercise levels attained and any of the cognitive variables.…”

“…In a study in an older COPD population, the 6-min walk test and pulmonary function tests were predictive of cognitive performance on various tasks. 24 According to the authors, older individuals who have COPD may be affected in 3 ways that are relevant to cognitive functioning. They may experience age-related declines in blood flow, disease-related declines in arterial oxygen content, and both age-and disease-related declines in physical activity.…”

“…Ayrıca yaşlı KOAH'lı olgularda kognitif fonksiyonların yaşla ilişkili olarak kan akımında azalma, eğitim durumu, hastalıkla ilişkili olarak arteryel oksijen içeriğinde azalma ve hem hastalık hem de yaş ile ilişkili olarak fiziksel aktivitede azalmayla etkilenebileceği belirtilmiştir (18)(19)(20) hasta grubumuzun da hipoksisi olmayan 50 yaş ve üs-tü hastalardan oluştuğu göz önüne alınırsa kognitif fonksiyonlardaki bu azalmada yaş ve KOAH nedeniyle ortaya çıkan sistemik inflamasyon, oksidatif hasar ve fiziksel aktivitedeki kısıtlanmanın rolü olduğu düşünü-lebilir. Ancak hasta ve kontrol grubu arasında yaş ortalamaları ve eğitim düzeyi açısından anlamlı farklılığın bulunmaması ve hasta grubunda SMMT sonuçlarının daha düşük olması KOAH'ın yaştan bağımsız olarak da kognitif fonksiyonlar üzerindeki olumsuz etkisini gös-termektedir.…”
