Breathlessness in older adults: What we know and what we still need to know

Abstract

Breathlessness is common among older adults, but it is often hidden as “normal aging “or considered narrowly as a symptom of cardio‐respiratory diseases. Studies on breathlessness in older adults are mostly focused on specific diseases, whereas older adults are characterized by multimorbidity and multi‐system age‐related impairments. This article aims to provide an overview of what is known so far on breathlessness in the general population of older adults and identify areas for further research. Research shows that breathlessness in older adults is a multifactorial geriatric condition, crossing the borders of system‐based impairments and diseases, and a valuable independent prognostic indicator for adverse outcomes. Further research needs to investigate (1) the multi‐factorial mechanisms of breathlessness in community‐dwelling older adults including the role of respiratory sarcopenia; (2) the influence of affective and cognitive changes of older age on the perception and report of breathlessness; (3) the best way to assess and use breathlessness for risk prediction of adverse outcomes in general geriatric assessments; and (4) the most appropriate multi‐modal rehabilitation interventions and their outcomes. Clinicians need to shift their approach to dyspnea from a disease symptom to a multifactorial geriatric condition that should be proactively searched for, as it identifies higher risk for adverse outcomes, and can be addressed with evidence‐based interventions that can improve the quality of life and may reduce the risk of adverse outcomes in older adults.

Age-related changes in the neural gating of respiratory sensations in humans

“…Moreover, previous studies have shown that higher age is associated with changed experiences of respiratory sensations such as breathlessness or dyspnoea [ 11 – 14 ]. For example, H egendörfer and D egryse [ 12 ] indicated that the prevalence of breathlessness ranged from 25% to 36% in older adults, and the prevalence increased with age. On the other hand, B attaglia et al .…”
