In sleep disorders, obstructive sleep apnea is the most common condition that’s seen, but a significant number of people with obstructive sleep apnea will also have central sleep apnea. Central sleep apnea is thought to be a condition that’s associated with a number of different neurologic problems, as well as heart or kidney failure. During the night, people with central sleep apnea stop breathing when signals in the brain that tells the body to breathe don’t work properly. No effort is even made to inhale. In contrast, with obstructive sleep apnea, an effort is made to breathe in, but because of collapse in the upper airways, air can’t get into the lungs.
