Introduction: Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease with a prevalence that increases with the aging of the subject. It presents a high prevalence of comorbidities, such as cognitive decline, which is gaining great clinical relevance in recent years. Factors such as pulmonary function, hypoxemia, hypercapnia or exacerbations contribute to the decline of cognitive functions. The nutritional status has been added to these factors as contributing to cognitive function decline when presenting in COPD. Objective: To evidence the relationship between cognitive decline, nutritional status and the clinical profile of patients admitted because of an acute exacerbation of COPD (AECOPD). Methods: 110 subjects hospitalized because of COPD, divided in two groups according to their nutritional status and assessment of cognitive decline at admittance, nutritional status and clinical profile. Results: Significant differences between groups concerning nutritional status in anthropometric variables (sex and IMC), functional ability (Barthel index and Daily Life Activities Scale), quality of life (Euroqol- 5D y SGRQ), sleep quality (Pittsburgh), mood (HAD) and cognitive decline (MoCa attention, MoCa abstraction). (p<0.05). Conclusion: Cognitive function is affected in COPD patients with an altered nutritional status when compared to those with a normal nutritional status. The nutritional decline is a factor contributing to the impairment of cognitive functions in this kind of patients, particularly a decline in attention and abstraction ability.
