The second type of sleep apnea is central sleep apnea
. This variant of the disorder is a lot more severe and hard to cure. This is because the apnea episodes are caused by the central nervous system itself. To put it simply, central sleep aponea occurs when your brain's programming for involuntary breathing is askew. This occurs mostly in people with heart conditions, more specifically atrial fibrillation. This type of sleep apnea is associated with the breathing disorders periodic breathing and Cheyne-Stokes respiration. It's very important to trace this early so that one many get psychotherapy, which is so far the best cure for it.
