[COPD and cognitive impairment].

Patients with chronic respiratory failure, especially COPD, suffer from a multi-systemic disease with organic, behavioral and social consequences that impact largely beyond the respiratory system. Cognitive impairment is associated with decreased quality of life and increased mortality in the general population, but remains underestimated and poorly studied in chronic respiratory diseases despite their increased prevalence. However, there is growing interest in research on the association between cognitive impairment and chronic respiratory diseases. Different risk factors, some modifiable, could contribute to the early development of cognitive disorders in this population. Patients with cognitive impairment need appropriate care to promote adherence to the therapeutic project. Respiratory rehabilitation, as a multimodal intervention, seems to have a positive effect on cognitive functions.
