Co-morbidities associated with obstructive sleep apnea.

There are many co-morbid conditions that are associated with obstructive sleep apnea (OSA). Though a causative relationship between OSA and some of the co-morbidities is well established or strongly associated, many risk factors of OSA (age, male gender and obesity) are also known risk factors especially for cardiovascular diseases. Other important co-morbid conditions associated with OSA are neurocognitive dysfunction and, erectile dysfunction. Recently there are reports that ocular manifestations are associated with OSA. It is expected that more co-morbidities will be reported in OSA as the research in this area progresses.
