Clinical Trial Summary

Research on the impact of lung diseases on neuropsychological functioning has revealed impaired cognitive processing in patients with a variety of pulmonary disorders. While the mechanisms responsible for the association of pulmonary diseases and neurocognitive functioning remain unclear, some researchers have attributed it to reduced oxygenation of the brain. Early detection and accurate management of comorbidity have benefits in reducing ILD morbidity and mortality.

Description:

Research on the impact of lung diseases on neuropsychological functioning has revealed impaired cognitive processing in patients with a variety of pulmonary disorders. While the mechanisms responsible for the association of pulmonary diseases and neurocognitive functioning remain unclear, some researchers have attributed it to reduced oxygenation of the brain. Interstitial Lung Disease (ILD) is an "umbrella" term as it comprises a variety of pulmonary diseases which affect the interstitium (the tissue and space around the air sacs of the lungs). It may be caused by a variety of factors (namely, inhaled substances, medications, infection, connective tissue disease, malignancy or idiopathic reasons) and has a clear negative impact on patients' quality of life, leading to symptoms such as fatigue, dyspnea and coughing. Physical sequelae include reduced lung volumes due to tissue thickening, sometimes caused by inflammation. A further consequence is reduced breathing efficiency, resulting in reduced blood oxygen levels and compromised exercise capacity. Additionally, the fibrosis of the parenchyma impedes the level of gas exchange. A number of studies have reported mood effects in ILD, suggesting, however, that the diagnosis of depression may be obscured, due to the fatigue and apathy that is often a consequence of ILD. Early detection and accurate management of Neuropsychiatric comorbidities have benefits in reducing ILD morbidity and mortality.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cognitive impairment	a 30-point test used to assess cognitive function; includes tests of orientation, attention, memory, language, and visual-spatial skills. MMSE score 24-30: no cognitive impairment, 19-23: mild cognitive impairment, 10-18: moderate cognitive impairment, = 9: severe cognitive impairment	1 MONTH
Primary	Anxiety level	consists of 14 items and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where a score = 17 indicates mild anxiety, 18-24 mild to moderate severity, and more than 24 moderate to severe anxiety	1 MONTH
Primary	Depression level	The original HAM-D has 21 items, but scoring is based only on the first 17. Scores less than or equal to 7 indicates normal response, 8-13 mild depression, 14-18 Moderate, 19-22 severe, and more than 22 very severe depression	1 MONTH
