Translating the Interplay of Cognition and Physical Performance in COPD and Interstitial Lung Disease: Meeting Report and Literature Review

Dmitry Rozenberg et al. Chest. 2024 Oct.

Abstract

Topic importance: Cognitive and physical limitations are common in individuals with chronic lung diseases, but their interactions with physical function and activities of daily living are not well characterized. Understanding these interactions and potential contributors may provide insights on disability and enable more tailored rehabilitation strategies.

Review findings: This review summarizes a 2-day meeting of patient partners, clinicians, researchers, and lung associations to discuss the interplay between cognitive and physical function in people with chronic lung diseases. This report covers four areas: (1) cognitive-physical limitations in patients with chronic lung diseases; (2) cognitive assessments; (3) strategies to optimize cognition and motor control; and (4) future research directions. Cognitive and physical impairments have multiple effects on quality of life and daily function. Meeting participants acknowledged the need for a standardized cognitive assessment to complement physical assessments in patients with chronic lung diseases. Dyspnea, fatigue, and age were recognized as important contributors to cognition that can affect motor control and daily physical function. Pulmonary rehabilitation was highlighted as a multidisciplinary strategy that may improve respiratory and limb motor control through neuroplasticity and has the potential to improve physical function and quality of life.

Summary: There was consensus that cognitive function and the cognitive interference of dyspnea in people with chronic lung diseases contribute to motor control impairments that can negatively affect daily function, which may be improved with pulmonary rehabilitation. The meeting generated several key research questions related to cognitive-physical interactions in individuals with chronic lung diseases.

Conceptual model of cognitive and motor control interactions affecting activities of daily living in people with chronic lung disease. Motor and cognitive skills can be considered as a hierarchy. Motor planning requires the selective integration of sensory neural input. Many activities of daily living require very complex cognition and motor control. The ability to perform activities of daily living may be improved through motor learning training strategies. This requires attention, motivation, and comprehension to learn a skilled task and then repetitive practice until the movement or complex action can be performed automatically. Factors such as dyspnea, fatigue, and pain may interfere with the ability to practice or move in a particular manner. Comorbidities can interfere with the desired motor action, whereas cognitive impairment could interfere with comprehension and retention.
