Introduction: The association of cognition, anxiety and depression with respiratory conditions, are nowadays of key interest in research. Understanding the correlation between the psychiatric symptoms and lung diseases will improve the quality of life for patients.

Aims and Objectives: The study aims to establish possible links between psychiatric pathologies and pulmonary obstructive diseases.

Methods: After obtaining ethical approval, we enrolled 52 subjects (20-86 years old) whom expressed written consent, with a history of obstructive lung disease, admitted at Leamna Pulmonology Hospital (October 2022-February 2023). We used the Mini Mental State Examination, Montreal Cognitive Assessment, Hamilton Anxiety-Depression Scale to evaluate cognitive, depression and anxiety levels.

Results: We found 19 (36.5%) with a history asthma (6 had severe asthma) and 33 (63.5%) with COPD (22 classified GOLD D). Of all, 10 (19.2%) patients had psychiatric history and medication. Patients without knowledge of inhaling medication performed poorly in the psychiatric questionnaires. Even though they had distinctive characteristics, the gravity of the psychiatrics pathology was inversely proportional with level of education and directly proportional with the severity of the respiratory pathology in all patients. Surprisingly, patients with a higher hospitalization rate were less likely to have severe depression or anxiety.

Conclusions: The COPD group performed poorly in the applied questioners compared to the Asthma group. Some subjects that had significant changes in psychiatric questioners, were not known with depressive, anxiety or cognitive disorders and needed psychiatric referrals.
