    Idiopathic hypersomnia

    Sleep patterns change with age, anxiety levels and many other factors. Normally, younger people have more concentrated periods of deep sleep compared to older people.

    Idiopathic hypersomnia is sleeping too much () without an obvious cause. It is different from narcolepsy, because idiopathic hypersomnia does not involve suddenly falling asleep or losing muscle control due to strong emotions (cataplexy).

    CPAP is an airway treatment of using slight positive pressure during inhalation to increase the volume of inspired air and to decrease the work of breathing.

    CPAP stands for “continuous positive airway pressure.” CPAP is a treatment that delivers slightly pressurized air during the breathing cycle. This keeps the windpipe open during sleep and prevents episodes of blocked breathing in persons with and other breathing problems. It is ...

    Obstructive sleep apnea

    Massively enlarged tonsils can cause episodes of cessation of breathing known as obstructive sleep apnea.  Cessation of breathing can last 10 seconds or longer, causing extremely low levels of oxygen in the blood.

    Obstructive sleep apnea is a condition in which the flow of air pauses or decreases during breathing while you are asleep because the airway has become narrowed, blocked, or floppy. A pause in breathing is called an apnea episode. A decrease in airflow during breathing is called a hypopnea episode. ...

    Polysomnography

    During a sleep study the sleep cycles and stages of sleep are monitored. Electrodes are placed to monitor continuous recordings of brain waves, electrical activity of muscles, eye movement, respiratory rate, blood pressure, blood oxygen saturation, and heart rhythm. Direct observation of the person during sleep may also be used. The test is performed for people who suffer from insomnia, excessive daytime sleepiness, obstructive sleep apnea, breathing difficulties during sleep, or behavior disturbances during sleep.
