Cognitive Assessment in Patient of Chronic Obstructive Pulmonary Disease

Backgrounds Chronic obstructive pulmonary disease (COPD) is a complex, multisystem disorder. Traditional measures of disease severity, such as airflow limitation, are poor markers of relevant patient outcomes, largely because they do not reflect the multisystem nature of the disease. Identification, understanding, and assessment of all relevant co-morbidities in COPD are needed to better characterize the full clinical spectrum of the disease. Cognitive impairment is one such co-morbidity with an emerging clinical relevance. In present case control study we aimed to do Cognitive Assessment in Patient of Chronic Obstructive Pulmonary Disease compared to a matched referral control group without any disease. Among patients with established COPD, we evaluated the impact of disease severity and impairment of respiratory physiology on cognitive impairment. Staging of COPD was done according to Global Initiative for chronic obstructive Lung Disease (GOLD). Cognitive impairment was defined as a Mini mental State Exam (MMSE) score of less than24 points.
