Difference Between Sleep Apnea And Insomnia
Apnea: Obstrutive due to dynamic narrowing of upper airway (nose/throat/wind pipe) by a large tongue, jaw deformities, obesity. Pt usually snores. Central apnea there is no obstruction, usually no snoring . Conditions like heart-kidney failure, stroke, sedatives cause brainstem to decrease respiratory drive when sleeping. Need to treat the conditions. ...Read moreSee 4 more doctor answers
Sleep apnea has two causes. It may be 'central' or 'obstructive'. Central apnea occurs as a disorder in the way the brain controls breathing. Obstructive sleep apnea is much more common and involves an anatomical blockage of the airway. Usually, the tongue blocks the airway, preventing the passage of air between the a sleep study is needed to diagnose particular ...Read more
Overlap: Nocturnal hypoxia is a drop in oxygen in the blood when sleeping. It's associated with sleep apnea, but also with hypoxic chronic bronchitis pulmonary hypertension and emphysema. Sleep apnea can be due to airway obstruction or of central origin. It causes reduced oxygen, often dangerously, and arousal from sleep, leading to daytime fatigue. ...Read moreSee 1 more doctor answer
Obstruction vs CO2: Central apnea is caused by the brain's inability to respond to elevated co2 (carbon dioxide) levels in the blood. Obstructive sleep apnea is caused by the collapse of the airway when the muscles of the throat, tongue, and possibly the palate when they are flaccid/paralyzed during the deeper stages of sleep. Osa responds well to CPAP and dental devices. Central may not. ...Read moreSee 1 more doctor answer
Different problems: Sleep apnea is a breathing-related sleep disorder involving brief periods that a person stops breathing while sleeping. This triggers an alarm system in the brain to wake the person up so he/she will start breathing again. Nocturnal panic attacks are discrete periods involving extreme anxiety associated with physiological changes in heart rate, breathing, sweating, etc. That occur at night. ...Read moreSee 1 more doctor answer
2 different condtion: sleep apnea is when there is a cessation of airflow with sleep and breathing. The most common type of sleep apnea is obstructive sleep apnea when the upper airway gets blocked. Nocturnal hypoxia is a general term for low oxygen with sleep. Sleep apnea can cause nocturnal hypoxia, though many other conditions can cause nocturnal hypoxia without sleep apnea such as copd or heart disease. ...Read more

Sleep paralysis: Normally a person cannot move much during REM sleep. Some people with narcolepsy spontaneously enter this state of paralysis while they are awake- this is called sleep paralysis. A memorable, lucid dream is not associated with narcolepsy, but there may be physiological paralysis during the dream. ...Read more
Unrelated: Obstructive sleep apnea is more of a physical problem. There is an obstruction in the airway during sleep (excess weight, collapsed tongue, enlarged tonsils, small pharynx, etc. Central sleep apnea is where the brain does not control breathing properly during sleep. Neither is related to PTSD. PTSD and sleep apnea can co-exist, but one does not cause the other or increase risk of the other. ...Read more
Closely: The symptoms of narcolepsy are those of parts of rem sleep intruding into wakefulness.

Unfortunately even well treated sleep apnea can result in daytime somnolence. There are medications which may help this. ...Read moreSee 3 more doctor answers
Initial study and CP: A sleep study is initially done to see if the patient has sleep apnea. If the patient has obstructive sleep apnea the patient is advised to have a study with CPAP to assess the best pressure to treat it with. The pressures are adjusted to eliminate the apneas (stop breathing) and to improve the patient's oyxgen saturation to keep it at or above 88%. ...Read more
Many causes: There are many reasons for problems with both sleep onset and maintenance. Illnesses such as alcohol abuse, depression, bipolar disorder and anxiety can be the cause. Metabolic illnesses such as hyperthyroidism are also a possibilities. In addition stimulants such as cocaine, amphetamines, decongestants, caffeine and nicotine can contribute to this. ...Read moreSee 1 more doctor answer
Apnea: Apnea is defined as a stopping of breathing- it can be caused by many different factors. Holding one's breath is a form of apnea. Medications can cause it as well. Sleep apnea is cessation of breathing while asleep and can be caused by airway obstructions ( tonsils, adenoids, deviated septum, enlarged uvula, sleeping on ones back allowing the jaw and tongue to drop back and block the airway.). ...Read moreSee 1 more doctor answer
This is the cessation of breathing for 10 seconds or more. Most apnea is obstructive being caused by collapse or obstruction of the airway leading to lack of air flow. However, it can be a central process, where the respiratory center of the brain fails to signal the respiratory respiratory system to initiate a breath. Lastly, some apnea is mixed central ...Read more
