Abstract

Chronic Obstructive Pulmonary Disease (COPD) is a public health problem which is increasing worldwide. Comorbidities usually occur in patients with COPD because COPD affects the physiological functions in a systemic manner. It has been reported that the ratio of cognitive impairment in COPD patients is higher than that of age-matched populations. Cognitive impairment thus has been proposed as a clinical manifestation in patients with COPD. Understanding all aspects of COPD and the effects of cognitive impairment on health outcomes for COPD patients therefore is essential for developing a holistic treatment.
