Central sleep apnea has to do with the brain and is linked to brain stem stroke
Central sleep apnea, or CSA, has different root causes. In patients with CSA, the brain does not send the normal signals to the diaphragm in order to expand and contract. There is not as much snoring with CSA, and this particular type of sleep apnea is associated with brain stem stroke. This is because the brain stem is the part of the brain that is responsible for breathing.
