The double-sidedness of cough in the elderly

Ha-Kyeong Won et al. Respir Physiol Neurobiol. 2018 Nov.

Abstract

Cough is a physiological reflex to protect airways against aspiration, but also it is one of the most frequent problems that lead patients to seek medical care. Chronic cough is more prevalent in the elderly than younger subjects, and more challenging to manage due to frequent comorbidities and possible side effects from drug treatment. Meanwhile, cough reflex does not decrease with natural aging but is often impaired by pathologic conditions like stroke. The impairment in cough reflex may lead to fatal complication like aspiration pneumonia. In this paper, we reviewed epidemiology and clinical considerations for chronic cough in the elderly, and summarized aging-related changes in cough reflex and also possible ways to normalize cough reflex and prevent aspiration pneumonia.
