It is caused by improper signaling from the brainstem to respiratory muscles and is triggered by either hypoventilation or hyperventilation. In adults, this disorder may arise following a stroke, congestive heart failure, trauma, infection or the use of narcotic medications. It is more common in older males and may present as a co-morbid condition to obesity. Clinical signs include snoring, insomnia or hypersomnia, difficulty concentrating and fatigue.
