A cortical contribution to breathing is determined by the presence of a Bereitschaftspotential, a low amplitude negativity in the averaged electroencephalographic (EEG) signal, which begins ∼1 s before inspiration. It occurs in healthy individuals when external inspiratory loads to breathing are applied. In chronic obstructive pulmonary disease (COPD), changes in the lung, chest wall and respiratory muscles produce an internal inspiratory load. We hypothesized that there would be a cortical contribution to quiet breathing in COPD and that a cortical contribution to breathing with an inspiratory load would be linked to dyspnoea, a major symptom of COPD. EEG activity was analysed in 14 participants with COPD (aged 57-84 years), 16 healthy age-matched (57-87 years) and 15 young (18-26 years) controls during quiet breathing and inspiratory loading. The presence of Bereitschaftspotentials, from ensemble averages of EEG epochs at Cz and FCz, were assessed by blinded assessors. Dyspnoea was rated using the Borg scale. The incidence of a cortical contribution to quiet breathing was significantly greater in participants with COPD (6/14) compared to the young (0/15) (P = 0.004) but not the age-matched controls (6/16) (P = 0.765). A cortical contribution to inspiratory loading was associated with higher Borg ratings (P = 0.007), with no effect of group (P = 0.242). The data show that increased age, rather than COPD, is associated with a cortical contribution to quiet breathing. A cortical contribution to inspiratory loading is associated with more severe dyspnoea. We propose that cortical mechanisms may be engaged to defend ventilation with dyspnoea as a consequence.

“…Breathlessness is a multidimensional symptom with a sensory and an affective component. It is commonly associated with anxiety, fear and depression in patients with chronic breathlessness [8][9][10]. A study [11] found that patients experiencing breathlessness under mechanical ventilation were eight times more likely to report anxiety than patients not experiencing breathlessness.…”

]. Chronic breathlessness is a distinct clinical syndrome defined as "breathlessness that persists despite an optimal use of the therapeutic resources available to treat the underlying causative condition" [1, 2]. This is a frequent clinical condition encountered in chronic respiratory diseases, cardiac diseases, neuromuscular disorders, terminal cancers, whether respiratory or not, and in patients receiving mechanical ventilation for acute or chronic respiratory failure. The above definition includes not only chronic conditions, but also acute breathlessness that persists despite maximal pathophysiological treatment. The term "persistent" breathlessness has been proposed to encompass both acute and chronic situations [2]. Persistent or not, breathlessness is under-recognised by respiratory physicians, particularly in settings of advanced palliative care or intensive care, where verbal communication is difficult [3, 4], thereby leading to calls for greater awareness of this problem [5, 6]. CURROW et al. [7] have pointed to the need to assess and treat chronic breathlessness with opioids as outlined in specialist clinical guidelines and argued that failure to do so is a breach of human rights. In this editorial, I expand further on this issue in the hope of clarifying potential moral and human rights issues in proper clinical management of chronic breathlessness or breathlessness in general. As breathlessness is an intensely traumatic event, the issue of proper psychological care of patients is also briefly addressed.
