Death could occur from untreated OSA due to lack of oxygen to the body. There is increasing evidence that<unk>  may lead to liver function impairment, particularly fatty liver diseases (see steatosis). It has been revealed that people with OSA show tissue loss in brain regions that help store memory, thus linking OSA with memory loss. Using magnetic resonance imaging (MRI), the scientists discovered that people with<unk>  have mammillary bodies that are about 20% smaller, particularly on the left side. One of the key investigators hypothesized that repeated drops in oxygen lead to the brain injury. The immediate effects of central<unk>  on the body depend on how long the failure to breathe endures. At worst, central<unk>  may cause sudden death. Short of death, drops in blood oxygen may trigger seizures, even in the absence of epilepsy. In people with epilepsy, the hypoxia caused by<unk>  may trigger seizures that had previously been well controlled by medications. In other words, a seizure disorder may become unstable in the presence of<unk> . In adults with coronary artery disease, a severe drop in blood oxygen level can cause angina, arrhythmias, or heart attacks (myocardial infarction). Longstanding recurrent episodes of<unk> , over months and years, may cause an increase in carbon dioxide levels that can change the pH of the blood enough to cause a respiratory acidosis.
