OSA and COPD Overlap Syndrome: Signs, Symptoms, and Mortality

By: Kevin Asp
March 5th, 2020

Two common sleep/pulmonary diseases are obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD). These two conditions can occur simultaneously creating a condition known as Overlap Syndrome, which creates two fold the uncomfortable disordered breathing conditions, according to the American Sleep Apnea Association. It results in long-term chronic health issues that go beyond your lungs, like heart disease and diabetes, and their linked myriad complications.

Axonal Degeneration in Soft Palate Nerves May Contribute to Obstructive Sleep Apnea

Obstructive sleep apnea (OSA), the intermittent cessation of breathing during sleep, occurs when the upper airway tissues (e.g., tonsils, fatty tissue) repeatedly collapse into the upper airway and partially or fully block airflow. The collapsibility of the upper airway in people with OSA is believed to occur because the upper airway muscles relax excessively during sleep, which allows structures supported by the muscles to collapse into the upper airway. Some research indicates that altered neuronal activation may contribute to the reduced tone of the upper airway muscles. Much of this research has focused on innervation of dilator muscles such as the genioglossus muscle (which forms the bulk of the tongue). However, another structure that contributes to obstruction is the soft palate. In recent years, scientists have begun examining whether neuronal injury in the soft palate muscles could contribute to OSA.
