Patients with COPD demonstrate decrease in areas of the brain that process breathlessness, fear, and sensitivity to pain:Patients with COPD Causes demonstrated gray matter decreases in areas of the brain that process breathlessness, fear and sensitivity to pain. The study found patients regionally decreased gray matter volume in the anterior, mid, and posterior cingulate cortex, hippocampus, and amygdala.
Levels of degeneration in certain areas of the brain were also impacted by longer disease duration. Those individuals showed a greater fear of breathlessness and fear of physical activity, which can affect the course of the disease.Chronic Obstructive Pulmonary Disease (COPD Causes), a condition impacting nearly 24 million Americans, is often associated with disease-specific fears and avoidance of physical activity.
COPD Causes Little is known of the structural brain processes that occur in patients. A study published in the February issue of the journal CHEST found that patients demonstrated gray matter decreases in areas of the brain that process breathlessness, fear and sensitivity to pain.Researchers tested 30 stable outpatients with moderate-to-severe COPD and 30 control subjects with no history of the disease.
