Question: what is the difference between sleep apnea and paroxysmal nocturnal dyspnea?
Answer: Paroxysmal nocturnal dyspnea vs. PND is a symptom that can be caused by a number of different respiratory and circulatory conditions. Sleep apnea, most commonly obstructive sleep apnea, on the other hand, is a medical condition on its own. Sleep apnea can cause PND, but not vice versa.
