Diagnosis of a sleep disorder begins with a medical history and physical exam. If an underlying medical condition is suspected, further tests such as blood tests may need to be done. A sleep study , called a polysomnogram, may be recommended. A multiple sleep latency test measures the speed of falling asleep. An arterial blood gas test may also be performed to check levels of carbon dioxide and oxygen.
Sleep deprivation can lower a person's quality of life and increase the risk for accidents.
Sleep disorders are not contagious and pose no risk to others. Treatments vary depending upon the specific sleep disorder. Sleep disorder clinics often help people return to normal sleep patterns. Sometimes, sleep disorders go away by themselves. Other times, medicines can be used.
