p seizures, sleep apnea patients have difficulty breathing while they sleep. Some sleep apnea patients become so relaxed it that their throat collapses and their airways close. As was the case with a man name John. John would relax and go into a deep sleep. His airway passage would close because his tongue had fallen to the back of his throat.

Sleep apnea also causes people to snore very loudly people at the highest risk for sleep apnea is obese men. Extrinsic sleep disorders are the opposite of intrinsic sleep disorders. Extrinsic sleep disorders are caused by factors outside the body (Dement 514). An example of an extrinsic sleep disorder is hypnotic dependent sleep disorder (Dement 515). This is the case with my uncle Allen. He cannot sleep without his pain pill. He takes it every night. He has even gone so far as to have many different doctors. So every one of them can prescribe him pain pills to help him sleep. This disorder is caused by a persons dependency on a sleeping aid. The person may feel they need a drug so often that they either need a higher dosage to sleep or they get to the point were they cant sleep without it, they are dependent. Sleep-onset association disorder is another type of an extrinsic sleep disorder (Dement 515). This disorder is characterized by the certain accommodations that need to be met in order to go to sleep. My mother-in-law is an example of a person with this disorder. She doesnt fall asleep watc...
