Describe the symptoms.

I need to write a research paper in APA format on sleep apnea. The three forms of sleep apnea are Obstructive, Central, and mixed. I need you to do these for each of the three forms: Describe what it is. Describe the symptoms. Describe how to diagnose someone who has sleep apnea. And describe all of the different treatments to help people with sleep apnea. Do this for each of the three forms of sleep apnea.
